 h3. Virtual environments inside distribution Python packages have moved
 
 The distribution packages that we publish for Python packages include an entire virtualenv with all required libraries. In Arvados 3.0 these virtualenvs have moved from @/usr/share/python3/dist/PACKAGE_NAME@ to @/usr/lib/PACKAGE_NAME@ to prevent conflicts with distribution packages and better conform to filesystem standards.
