spyder/juypter not working after downgrading python

Question

I had to download my python version from 3.5 to 3.4 because one of the packages I needed wasn\'t supported in 3.5. I downgraded the python version using the conda command promp

Answer 1

After a day of searching I finally figured it out. I initially used

conda install python=3.4

Bad idea - ended up having to do a fresh install of anaconda to get spyder and juypter working again.

What ended up working is creating a separate environment.

conda create -n py34 python=3.4 anaconda
activate py34
... then install packages ...

This added spyder(py34), juypter(py34), and all its "py34 brothers and sisters" to my start menu. Using these new shortcuts/environment, I now have access to the packages I need by choosing the appropriate short cut. Yes, my start menu has extra python shortcuts now, but whatever - it works.

Just make sure Make sure you install the packages you're looking for before you close the anaconda console. Perfect for installing theano dependencies mingw and libpython.
