[HANDS-ON BUG] Bonus Unit 1: Training Huggy the Dog

[LelandB]

Describe the bug

Cannot train the model using ml-agents as the colab notebook runs into an error that earlier steps were trying to avoid using virtual-env. Is there a missing step from the colab notebook - I ran the step that updates the version from 3.12.11 to 3.15.5.

/bin/bash: line 1: mlagents-learn: command not found

Please share your notebook link so that we can reproduce the error

Hi,

This is likely because the version of python doesn´t match the required version for ML-Agent as explained in the Collab doc. Note that the cell used to change the version of python is not working due to a requirement to accept the license of conda before creating a new virtual env, so before running the cell starting with:

# Install virtualenv and create a virtual environment

update the code and add these two lines before the "conda install" command.

!conda tos accept --override-channels --channel https://repo.anaconda.com/pkgs/main
!conda tos accept --override-channels --channel https://repo.anaconda.com/pkgs/r

Then run the cell and finally run the cell to get the python version it should now be 3.10.12

Good luck with the training!
