# Due to an issue with Python 3.10 and poetry, if we use a poetry virtual env,
# we need to disable the option: poetry config experimental.new-installer false
# check https://github.com/python-poetry/poetry/issues/4210
# However, if we run poetry config virtualenvs.create false, then we dont.
# Do not create a virtual poetry env as we already are in an isolated container
