BrokenPipeError and EOFError Please help

[ninazrdl]

The training process was running fine and suddenly it throws these errors. The first few episodes are fine. I used this command with a virtual env, with and without anaconda: mlagents-learn trainer_config.yaml --env=UnityProject.exe --run-id=1 --train. A window alerting me that Python stopped working comes together with the following error log:

2020-04-18 07:53:22 INFO [trainer.py:214] 2: Brain: Step: 110000. Time Elapsed: 6598.126 s Mean Reward: 1.000. Std of Reward: 0.000. Training.

During handling of the above exception, another exception occurred:

raise EOFError​
EOFError

Environment:

• OS: Windows 10
• _ML-Agents 0.15.1
• _TensorFlow 2.0.1 or 1.15.2 Tried both PPO and SAC. Neither of them works. The error comes while training and it's not always at the same step.
