1. System Info

pypots v0.13

2. Information

  • The official example scripts
  • My own created scripts

3. Reproduction

PyPOTS/pypots/nn/modules/base_model_core.py

Line 48 in 0259a6c

def calc_criterion(self, inputs: dict) -> dict:

4. Expected behavior

It fails because the model is wrapped in DataParallel, which only provides forward() for parallel running.
