possibility of using several virtual environments simultaneously
Yes.

Create two virtual environments.

Call them v1 and v2

Open terminal x 2

First terminal - activate v1 and install your library 1

Second terminal - activate v2 and install your library 1
hello I noticed that some of the libraries I use are used for development but also for analysis and sometimes I have to use both is there a way to use a basic virtual environment as in the templates and can I use the two libraries a few times simultaneously
