As of 18 feb 2022, newly createdpython 3.7+ code envs may fail to train models with the following error message :
Failed to train : <class 'ImportError'> : cannot import name 'soft_unicode' from 'markupsafe' (/home/ubuntu/dss-home/code-envs/python/visualml/lib/python3.7/site-packages/markupsafe/__init__.py)
This is due to Markupsafe releasing a new version incompatible with other libs in the code env.
To avoid/fix the problem, one has to manually pin Markupsafe to the 2.0.1 version.
This is done by adding
to the list of requested packages in the code env, and rebuilding it.
Operating system used: Ubuntu 18.04
