Description
Modin version checks
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest released version of Modin.
-
I have confirmed this bug exists on the main branch of Modin. (In order to do this you can follow this guide.)
Reproducible Example
import ray
import modin.pandas as pd
## Option 1 UserWarning
ray.shutdown()
ray.init(address="ray://",runtime_env={"pip": ['modin']})
@ray.remote
def cause_error():
data = {'id': ["ajajajajajjajajajajajaja", "jajjajajajajajajajajja"]}
df = pd.DataFrame(data)
return df
result_df = ray.get(cause_error.remote())
print(result_df)
## Option 2 Import Error
ray.shutdown()
ray.init(address="ray://",runtime_env={"pip": ['modin'], "env_vars": {"__MODIN_AUTOIMPORT_PANDAS__": "1"}})
@ray.remote
def cause_error():
data = {'id': ["ajajajajajjajajajajajaja", "jajjajajajajajajajajja"]}
df = pd.DataFrame(data)
return df
result = ray.get(cause_error.remote())
print(result_df)Issue Description
When installing modin via runtime_env in ray.init() on an pre-initialised ray-cluster, Modin will either throw a UserWarning for every Modin Function call to import the Modin Autoimport as a Variable. When importing the variable, it will throw an import error: the modules numpy, putz, dateutil are not found. When installing the packages separately in ray.init() this does not work either and it will throw the same error. I dont know whether the code is reproducable because i can not share the ray cluster ip adress.
Expected Behavior
Modin should install itself on the Ray Cluster without throwing any Warnings or Errors.
Error Logs
(cause_error pid=8379) UserWarning: When using a pre-initialized Ray cluster, please ensure that the runtime env sets environment variable __MODIN_AUTOIMPORT_PANDAS__ to 1
(cause_error pid=8379) UserWarning: Distributing <class 'dict'> object. This may take some time.
