Hello,

I have a philosophical question. I need to use python 3.5 and some packages as matplotlib, numpy, scipy, jupyter. If know the problem from debian, if I install some packages with apt-get (pacman) and some with pip3 then i can have problems with actualizations. I think, the best way is to install only python and python-pip with pacman and all others packages with pip. Is this idea correct? What is the best to do with this kind of problem?

Thanks

Rafael

Answer is the same as yesterday:

Again, make sure to update, this time python 3.5.1 (and builds for all that depend on it) moved to all users yesterday.

And again, in a rolling distro don't go around the package manager for installing. For packages you miss:

(python3 versions of many are available there, including at least numpy & scipy)
