The only thing I must install with pip is tensorflow-gpu. For everything else, I make use of the Ubuntu repositories. The Synaptic package manager installs packages (including Python modules) for all user accounts at the same time, which I like. When I installed tensorflow-gpu using pip, I was in fact frustrated because I couldn't figure out how to deploy it across multiple user accounts at one time. I ended up installing it three times, once in each account. You're suggesting that's actually preferred, at least when pip is performing the installation. OK, I will endure the repetition. -- https://mail.python.org/mailman/listinfo/python-list
