Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the efficiency of exception handling, embodiments of the present invention provide a task exception handling method, a task exception handling device, and a task exception handling system.
It should be noted that the embodiments of the present invention can be applied to various electronic devices, such as personal computers, servers, smart mobile devices, and other devices having data processing capability. Moreover, the task exception handling method provided by the embodiment of the invention can be realized in a software, hardware or a combination of software and hardware.
As shown in fig. 1, a schematic diagram of a task exception handling system provided in an embodiment of the present invention includes a training server 101 and an exception handling terminal 102, where the training server 101 and the exception handling terminal 102 are in communication with each other, the training server 101 is configured to run a training task, and the exception handling terminal 102 may monitor the training task running in the training server 101 in real time, so as to execute a task exception handling method provided in an embodiment of the present invention.
The training server and the exception handling terminal can be realized by software, hardware or a combination of software and hardware. For example, the training server may be a server, and the exception handling terminal may be a client computer, or the training server and the exception handling terminal are software, and the training server and the exception handling terminal may be deployed on the same server or client.
The algorithm training system is briefly described below. The algorithm training system is a system for generating a model by training an algorithm, and the algorithm training system can be deployed on at least one server. For example, the algorithm training system may train the CNN algorithm to obtain a face recognition model for face recognition. A simple algorithm training process includes: acquiring training data; processing the training data by using an algorithm to be trained to obtain a processing result; and judging whether the processing result meets the expectation, if not, adjusting the parameters of the algorithm, carrying out next training, and if so, finishing the training of the algorithm to obtain a trained algorithm model. In the embodiment of the present invention, the process of acquiring the training data each time, obtaining the processing result by using the algorithm data, and adjusting the parameters of the algorithm is referred to as a training task.
The algorithm training system may be abnormal during each execution of the training task. For example, an exception due to an environmental problem with the algorithmic training system, an exception due to a problem with the input data of the training task, an exception due to an error in the running of the code logic of the algorithmic training system, and the like. When an abnormality occurs in the running process of the training task, the abnormality occurring in the running process needs to be processed. In the related art, a manual processing mode is mostly adopted, that is, after the training task runs abnormally, a worker needs to be informed to manually process the abnormal running of the training task so as to recover the normal running of the algorithm training system. However, with the scale expansion of the algorithm training system and the increase of training tasks, the frequency of the training tasks having abnormalities in the algorithm training process is higher and higher, and the efficiency is lower only through a manual processing mode.
Illustratively, the training task is a training task for a neural network algorithm, and the algorithm model is a neural network algorithm model.
In order to solve the technical problem of low exception handling efficiency, an embodiment of the present invention provides a task exception handling method, including:
when the target training task in the algorithm training system is detected to be abnormal in operation, acquiring a target abnormal reason causing the abnormal operation of the target training task;
judging whether a preset processing strategy corresponding to the target abnormal reason exists or not;
if the target training task exists, processing the abnormity occurring in the operation of the target training task according to a processing strategy;
and if not, outputting a notification message aiming at the target training task, and storing a processing strategy which is configured by the configuration operation and corresponds to the target abnormal reason when the configuration operation aiming at the target abnormal reason is received.
In the above-mentioned scheme provided by the embodiment of the present invention, when a processing policy corresponding to a target exception cause exists, the exception can be processed according to the processing policy, so that the exception is automatically processed, and the exception processing efficiency is improved.
The task exception handling method according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 2, a task exception handling method provided in an embodiment of the present invention may include the following steps:
s201, when the abnormal operation of a target training task in the algorithm training system is detected, acquiring a target abnormal reason causing the abnormal operation of the target training task;
the target training task may be any training task with abnormal operation in the algorithm training system. When the algorithm training system only needs each training task, the running state of each training task in the algorithm training system can be monitored in real time, and when any training task in each training task runs abnormally, the training task running abnormally can be determined as the target training task.
It should be noted that, for the algorithm training system, after any training task runs abnormally, the algorithm training system may generate an abnormal code for the training task with the abnormal operation, and the abnormal code may indicate an abnormal reason of the training task with the abnormal operation, so that the execution subject in the embodiment of the present application may obtain the reason that the target training task runs abnormally by calling a preset interface of the algorithm training system.
Specifically, a task log when the operation of the target training task is abnormal can be obtained through a query interface provided by the algorithm training system. The algorithm training system can generate a task log after the training task is abnormal in operation, wherein the task log records abnormal reasons when the training task is abnormal in operation, such as fault codes, and the like, except for recording the abnormal reasons causing the training task to be abnormal in operation, the task log can also record attribute information of input data of the training task, such as data identification, data format and the like, or can also record abnormal positions when the training task is abnormal in operation, such as the abnormal occurrence in a data acquisition stage, the abnormal occurrence in a data processing stage and the like.
In the embodiment of the present invention, the obtained exception cause may be a target exception cause, and then a subsequent processing step is performed, where the exception cause may be an exception cause identifier, such as a fault code.
S202, judging whether a preset processing strategy corresponding to the target abnormal reason exists or not;
the processing policy corresponding to the abnormal cause may be preset for the abnormal cause, and the processing policy corresponding to the abnormal cause is used to instruct to automatically process the abnormality caused by the abnormal cause. For example, for an exception of training task interruption, the target exception cause is an input error, and the preset processing policy is: the input data is retrieved.
Because there are many exceptions that appear in the training task running process, some exceptions are frequently appeared, and the probability of some exceptions is low, and the exceptions that appear in the training task may be unexpected exceptions, and the exception causes are various, therefore, it is difficult to preset a corresponding processing strategy for each exception cause that causes an exception. Therefore, the exception cause existing in the corresponding processing strategy is often only a part of exception causes, and generally speaking, the exception cause existing in the corresponding processing strategy is often an exception cause which appears more frequently and/or has appeared historically.
Therefore, it is possible to search for whether or not a processing policy corresponding to the target abnormality cause exists from the correspondence relationship between the abnormality cause and the processing policy established in advance. If there is a preset processing strategy corresponding to the target exception cause, step S203 may be executed to automatically process the exception occurring during the operation of the target training task based on the corresponding processing strategy, and if there is no preset processing strategy corresponding to the target exception cause, step S204 may be executed to manually process the exception occurring during the operation of the target training task.
S203, processing the abnormity occurring in the operation of the target training task according to a processing strategy;
in this step, when it is determined that a preset processing strategy corresponding to the target abnormal reason exists, it is indicated that a processing strategy for processing the abnormality occurring during the operation of the target training task is preset, and at this time, the abnormality occurring during the operation of the target training task can be processed according to the processing strategy corresponding to the target abnormal reason, so that when the operation of the target training task is abnormal, the automatic processing of the abnormality is realized.
For example, for an exception of training task interruption, the target exception cause is an input error, and the corresponding processing policy is: if the input data is reacquired, the algorithm training system can be informed to reacquire the input data once.
And S204, outputting a notification message aiming at the target training task, and storing a processing strategy which is configured by the configuration operation and corresponds to the target abnormal reason when the configuration operation aiming at the target abnormal reason is received.
The output notification message for the target training task may be used to indicate that an exception occurring during the operation of the target training task is manually handled.
In this step, when it is determined that there is no preset processing strategy corresponding to the reason of the target anomaly, it is indicated that there is no preset corresponding processing strategy for the target anomaly, and at this time, the anomaly occurring during the operation of the target training task cannot be automatically processed. In order to handle the exception in time, a notification message for the target training task may be output, so as to notify a developer to manually handle the exception occurring during the operation of the target training task.
For example, the notification message may be "target training task exception, please process" to remind the developer to manually process the exception occurring during the operation of the target training task. Of course, besides characters, other forms such as video, pictures, audio, and the like may also be used as the presentation form of the notification message, which is not specifically limited in the embodiment of the present invention. Optionally, the notification manner of the notification message includes any interaction manner such as a short message, an application message, a mail, and a telephone, which is not specifically limited in this embodiment of the present application.
When it is determined that there is no preset processing policy corresponding to the target abnormality cause, the processing policy corresponding to the target abnormality cause configured by the configuration operation may be stored when the configuration operation for the target abnormality cause is received.
The configuration operation may be an operation of configuring the processing strategy by a developer for an abnormal reason causing an abnormality in the operation of the target training task, so that when the abnormality caused by the abnormal reason is encountered again in the following process, the automatic processing according to the configured processing strategy may be performed.
In the above scheme provided by the embodiment of the application, when a processing policy corresponding to a target exception cause exists, the exception can be processed according to the processing policy, so that the exception is automatically processed, and the exception processing efficiency is improved.
Optionally, in an embodiment, the task exception may be automatically handled by using a test case.
The test case is used for indicating and generating a test task for testing the algorithm training system, the test task can be understood as a training task for testing, and the test case generally contains various parameters required by testing, such as formats of input data and the like.
In the embodiment of the invention, when the test cases are used for automatically processing the task exception, the test cases can also contain exception reasons, each test case is correspondingly provided with a case state, and the case state is used for indicating whether the test case contains a processing strategy corresponding to the exception reason. For example, if the case state of a test case is a complete state, the test case further includes a processing policy corresponding to the abnormal reason, whereas if the case state of a test case is an incomplete state, the test case does not include a processing policy corresponding to the abnormal reason.
It is emphasized that the test cases provided by the embodiments of the present invention are different from the test cases in the related art. For the test cases in the related art, each test case only contains various types of parameters required by the test, and indicates the parameters for generating the test task. The test case provided by the application is set for the abnormal reason, at least comprises the abnormal reason, and can also comprise a processing strategy corresponding to the abnormal reason. Of course, the test cases in the embodiment of the present application and the test cases in the related art are different in generation manner and function, and will be described in detail in the following embodiments.
The test case may be stored in a test case library, where the test case library is a database storing test cases, and the test case library may be deployed on the same device as the training server and/or the exception handling terminal, or may be deployed independently of the device where the training server and the exception handling terminal are located.
Illustratively, when the test case is required to be used for testing the algorithm training system, the exception handling terminal may send a test instruction to the training server, instruct the training server to obtain the test case indicated by the test instruction from the test case library, and then the training server executes the test task according to various parameters required by the test included in the obtained test case.
After the target abnormal reason is determined, whether a test case containing a processing strategy corresponding to the target abnormal reason exists or not can be searched based on the target abnormal reason, and whether the processing strategy corresponding to the target abnormal reason exists or not is determined.
Therefore, when there is no preset processing policy corresponding to the target abnormality cause, in order to automatically process the abnormality caused by the target abnormality cause when the abnormality caused by the target abnormality cause is encountered again, a test case including the processing policy corresponding to the target abnormality cause can be generated.
In this case, before outputting the notification message for the target training task, a test case that includes the cause of the target abnormality and has a case status of incomplete may be generated based on the training data of the target training task.
The training data of the target training task may include at least one of input data, an input format, an input position, a trained algorithm model, model parameters when the task is abnormal, environment data of the training task, a stage where the task is abnormal, and the like, and the training environment of the task may include parameters such as a component called by the algorithm model.
After the training data of the target training task is acquired, a test case which contains the reason of the target abnormality and has an incomplete case state can be generated based on the training data of the target training task. Optionally, the test data required for constructing the test task, for example, data input by the target training task, a format of the input data, a trained model, model parameters when the task is abnormal, and the like, may be determined from the training data of the target training task, and further, the cause of the target abnormality is recorded in the test case, and the state of the test case is set to be incomplete, so as to generate a test case that includes the cause of the target abnormality and has an incomplete case state.
For example, the exception handling terminal may read test data required for constructing the test task from the training server terminal, and then write the test data into the test case library according to an agreed storage format of the test case to obtain the test case, and further write the target exception cause into the obtained test case, and further set the state of the test case in the test case library to be incomplete through a state control instruction. The test case library may be deployed in a device where the exception handling end is located, or may also be deployed in a device where the training server end is located.
After generating the test case which includes the target abnormal cause and has an incomplete case state, if a configuration operation for the target abnormal cause is received, a processing policy corresponding to the target abnormal cause and configured by the configuration operation may be set in the generated test case, and the case state of the generated test case may be set to be a complete state.
In the case of implementing automatic processing of task exception by using test case, the determining whether there is a preset processing policy corresponding to a target exception cause may include:
judging whether a first test case which contains a target abnormal reason and is in a finished state exists or not;
optionally, after the target abnormality cause is determined, a first test case which contains the target abnormality cause and is in a complete state may be searched from the test cases contained in the test case library.
In an implementation manner of the determination, a test case in a complete state may be determined from test cases included in a test case library, and the test case may be used as a preliminary screening test case, and then a test case including a target abnormality cause may be searched from the preliminary screening test cases. And if the test case containing the target abnormal reason is found, taking the test case as a first test case, and if the test case containing the target abnormal reason is not found, judging that the first test case does not exist.
In another implementation manner of the determination, a test case including a target abnormal reason may be first searched from each test case included in the test case library, and if the test case including the target abnormal reason is not found, it may be directly determined that the first test case does not exist; otherwise, if the test case containing the target abnormal reason is found, the case state of the found test application is further determined, if the test case is not in the completed state, the first test case is judged to be absent, and if the test case is in the completed state, the found test case is used as the first test case.
After the first test case which contains the reason of the target exception and is in the finished state is found, the exception occurring in the operation of the target training task can be processed according to the processing strategy in the first test case.
Optionally, after the test case which contains the target exception reason and is in the complete state is found, the test case is read from the test case library, and the exception occurring in the operation of the target training task is further processed according to the processing strategy in the test case, so that the exception is automatically processed.
In the above scheme provided by the embodiment of the invention, the test case includes the abnormal reason and can include the processing strategy corresponding to the abnormal reason, so that the processing strategy corresponding to the target abnormal reason can be quickly and accurately obtained by searching the test case, and a realization basis is provided for improving the abnormal processing efficiency.
In one embodiment, each test case further includes: the method is used for verifying whether the processing of the exception caused by the included exception cause is valid, wherein the verification data can be understood as various parameters required for generating the test task, such as the format of the input data, the position of the input data, various model parameters in the runtime and the like.
At this time, in order to ensure the effectiveness of processing the exception occurring during the operation of the target training task, after the exception occurring during the operation of the target training task is processed according to the processing strategy in the first test case, the first test case may be used to verify whether the processing for the exception is effective.
Optionally, the first verification task may be run based on verification data in the first test case, where each verification task is used to verify whether processing for the exception is valid; and if the first verification task runs normally, determining that the abnormal processing of the running of the target training task is completed.
The verification data in the first test case is data used for constructing a target verification task, such as an identifier of input data or indication data, a trained algorithm model, an executed training strategy and the like. If the first verification task runs normally, it indicates that no abnormal reason causing the abnormality exists in the current algorithm training system, and at this time, it can be determined that the processing of the abnormality occurring in the running of the target training task is completed, that is, the processing of the abnormality occurring in the running of the target training task is effective.
In the above scheme provided by the embodiment of the present invention, a target verification task identical to the target training task may be constructed by using a test case including a target abnormality cause, and whether processing for the algorithm training system is effective or not may be verified by using the target verification task.
Optionally, if the first verification task runs abnormally, displaying the abnormality of the target training task during running, so as to manually process the abnormality of the target training task during running.
If the first verification task runs abnormally, it is indicated that an abnormal reason causing the abnormality still exists in the current algorithm training system, that is, the automatic processing of the algorithm training system is invalid, at this time, the abnormality occurring in the running of the target training task can be displayed, for example, prompt information is generated in a display screen to inform a worker to manually process the abnormality which is invalid in the automatic processing.
Optionally, after each manual processing is completed, the step of executing the verification data based on the first test case and running the first verification task may be returned until the first verification task runs normally, that is, until the abnormality occurring during the running of the target training task is effectively processed.
When the first verification task runs normally, it is indicated that the exception caused by the target exception reason is effectively processed, and since the processing policy in the first test case cannot effectively process the exception caused by the target exception reason, the processing policy in the first test case needs to be updated.
Therefore, if an update operation of the processing policy for the target exception cause is received, the processing policy in the first test case can be updated according to the update operation, so that the processing policy in the first test case can effectively process the exception caused by the target exception cause.
Optionally, in another embodiment of the present invention, in a case that each test case further includes verification data for verifying whether processing for an exception caused by the included exception reason is valid, in the generated test case, a processing policy corresponding to a target exception reason and configured by a configuration operation is set, and before a case state of the generated test case is set to a completion state, a second verification task may be executed based on the verification data in the generated test case.
The second verification task is used to verify whether the processing policy configured by the configuration operation can effectively process the exception caused by the target exception reason, and if the second verification task is operating normally, it indicates that the processing policy configured by the configuration operation can effectively process the exception caused by the target exception reason.
Optionally, if the second verification task runs abnormally, it is described that the processing strategy configured by the configuration operation cannot effectively process the abnormality caused by the target abnormality, at this time, the worker needs to be prompted to manually process the abnormality again, that is, the abnormality occurring during the running of the target training task is displayed, the processing of the abnormality occurring during the running of the target training task is prompted, after the processing of the abnormality of the second verification task is completed, the step of executing the verification data based on the generated test case is returned, and the step of running the second verification task is executed until the second verification task runs normally.
In the above scheme provided by the embodiment of the present invention, the verification task can be run through the verification data in the first test data, so that the exception can be effectively handled, and the processing policy recorded in the test case can be effectively exception.
In order to more clearly illustrate the embodiment of the present invention, as shown in fig. 3, the embodiment of the present invention further provides a framework flowchart of task exception handling, which includes a monitoring module, a data collection module, and an automatic verification module.
The monitoring module can detect the training task state of a training task in the algorithm training system in real time, and when the training task fails, an abnormal task training report of the failed task can be generated to provide basic information for subsequent analysis.
The data acquisition module can acquire the related information of the abnormal training task from the training system, acquire the abnormal task training report generated by the monitoring module, analyze the training report, extract the information recorded in the abnormal task training report, further perform preliminary judgment and classification on the failure reason of the failed task, and divide the failed task into tasks capable of being automatically repaired, such as: data format problems, or non-automatic repair tasks, such as: code logic problems. When the data acquisition module analyzes that the failed task is the task which can be automatically repaired, the automatic repair flow can be executed, and when the failed task is analyzed to be the task which can not be automatically repaired, a mail is sent to inform a corresponding developer so as to manually process the abnormity.
The automatic verification module is used for initiating the same training task once again according to the abnormal training task test case acquired by the data acquisition module after the related repair means (automatic repair or manual repair) is executed, so as to verify the repair result after the abnormal repair.
The following is illustrated with reference to examples:
in an example, the target training task is a speech recognition task a for training a speech recognition model, when an error occurs in the operation of the speech recognition task a, it is determined that the target anomaly is caused by loss of input data, and after the execution of the repairing means is completed, a speech recognition task a identical to the speech recognition task a can be automatically generated to verify whether the input data can be successfully acquired.
In the second example, the target training task is a video identification task B for training a video identification model, when an error occurs in the running of the video identification task B, it is determined that the reason of the target abnormality is coding failure, and after the execution of the repair means is completed, a video identification task B identical to the video identification task B can be automatically generated to verify whether coding can be successfully performed.
In the third example, the target training task is a picture classification task C for training a picture classification model, when an error occurs in the operation of the picture classification task C, it is determined that the target abnormality is component loss, and after the execution of the repair means is completed, a picture classification task C identical to the picture classification task C can be automatically generated to verify whether the component is still lost.
And in the fourth example, the target training task is a face recognition task D for training a face recognition model, when the face recognition task D has an error in operation, the target abnormal reason is determined to be the loss of the labeled data, and after the execution of the repairing means is finished, a face recognition task D which is the same as the face recognition task D can be automatically generated to verify whether the labeled data can be successfully obtained.
And in the fifth example, the target training task is a license plate recognition task E for training a license plate recognition model, when the license plate recognition task E has an error in operation, the target abnormality is determined to be caused by the loss of the labeled data, and after the repair means is completed, a license plate recognition task E identical to the license plate recognition task E can be automatically generated so as to verify whether the labeled data can be successfully obtained.
And in the sixth example, the target training task is a motion recognition task F for training a motion recognition model, when an error occurs in the operation of the motion recognition task F, the reason of the target abnormality is determined to be a feature extraction error, and after the execution of the repairing means is completed, the motion recognition task F which is the same as the motion recognition task F can be automatically generated to verify whether the feature can be successfully extracted.
And in the seventh example, the target training task is a foreground and background distinguishing task G for training a foreground and background distinguishing model, when the foreground and background distinguishing task G has an error in operation, the target abnormity reason is determined to be the error in operation of the model, and after the execution of the repairing means is finished, the foreground and background distinguishing task G which is the same as the foreground and background distinguishing task G can be automatically generated so as to verify whether the model can be operated successfully.
After the automatic verification module passes the verification, the data acquisition module collects the information of the current failed task and the solution, and the solution is added into the case library to ensure the richness of the system test cases and the completeness of the automatically repairable scene, so that the case library can be used for carrying out comprehensive test in the development and test stage, and the stability and the robustness of the system are ensured.
In the above scheme provided by the embodiment of the present invention, when a processing policy corresponding to a target exception cause exists, the exception can be processed according to the processing policy, so that automatic processing of the exception is realized, and the exception processing efficiency is improved. Furthermore, the case library can be used for carrying out comprehensive testing in the system development and testing stage, and the stability and the robustness of the system are guaranteed.
