How can I use both Anaconda versions (2.7 & 3.5)?

Question

I was using the Anaconda 3.5 distro in a Windows 10 machine. Due to dependencies in libraries that I want to work with, I had to have the 2.7 version i

Answer 1

You can make Python 3.5 environment with your Anaconda 2.7:

conda create -n py35 python=3.5

Now, activate it:

activate py35

Finally you can install the desired packages:

conda install numpy

or, the whole anaconda:

conda install anaconda

The advantage of this approach is that you can also create Python 3.4 or 3.6 environments. Furthermore, you can create environments with different combinations and versions of libraries.

Actually, it makes sense to create a new environment for each larger project.
