Hello,
I'm a french student and I'm running Python 3.5.2 on windows.
When I installed Anaconda3 4.2.0 version, Pyzo couldn't find a module named
conda.
Then I registered it as my default Python 3.5.2 version, but I couldn't use
Pyzo anymore (I sent you a screenshot). So I tried to fix this problem
f
your use case. Yes, I'm willing to have missed something subtle (or not
so subtle).
