Creation of virtual environments is done through the venv module. Installing packages into an active virtual environment uses the commands shown above.

A number of scientific Python packages have complex binary dependencies, and arent currently easy to install using pip directly. At this point in time, it will often be easier for users to install these packages by other means rather than attempting to install them with pip.

Some of the solutions for installing scientific software that are not yet available as pre-built wheel files may also help with obtaining other binary extensions without needing to build them locally.
