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
