Theano: Lazylinker_c.py raises import error

[dawidjk]

Hi, I am following the guide that is on deeplearning.net for windows install, and I got to the test phase, but when I try to run it, I get this error. I believe it is related to the lazy linker.
Thank you!

Hi,

You probably missed one step of the installation process on Theano/Python.
If you use conda, this would fix it:

conda install mingw libpython

I created a new libpython with mingw based off of my python34.dll and it worked for a while, but I think I changed something in path and it isnt working again :(

[dawidjk]

Okay, I got it. Mingw was just being weird. Thank you so much though!
