As users (especially not experts one) just follow the instructions sequentially, I think it is better to first specify that a virtual environment needs to be created, and only after specify how to install the package via pip.
Otherwise, the risk is that users will install in a globally visibile location python libraries via pip in a version that is not compatible with apt installed software.
