This is an archive of the Python venv generated by this Evergreen build.
You can use it locally to avoid needing to manually set up the Python environment.
Before activating it you should adjust it for your local environment.
Run the following commands to do that:
echo "Updating virtual env directory in activate script"
pushd venv; venv_dir=\$(pwd); popd
EOF
if [ "Windows_NT" = "$OS" ]; then
cat << EOF >> venv_readme.txt
