OnActionReceived always returns zero values #5672

Closed dimok135 closed 2 years ago

dimok135 commented 2 years ago

When I start training 3DBall demo scene, OnActionReceived always returns zero values, so the cubes never rotate. Neither unity nor python shows any errors. I'm using Unity 2020.3.25f1, ML Release 18 (v2.1.0-exp.1, Python Package 0.27.0) Changing old Input system to the new version didn't help.

P.S. The same python package is working fine with an old version of mlagents on Unity 2018.

From the video it seems like you're using very old version of the ml-agents and ml-agents-env packages (0.17 for both versions.)

Version 2.1.0-exp.1 of the ML-Agents Unity package depends on v0.27.0 of the python packages. Also, we no longer support TensorFlow. Please update the python packages, as well as, switch to PyTorch for the best results.

miguelalonsojr, Thank you very much! I had a mess in my python environment, so when I updated mlagents to 0.27, pip did something strange. I have checked it and now it works fine!
