导入theano的anaconda python错误

Question

I'm quite new in python and of course I'm also new with Theano. I'm trying to use it under windows along with anaconda python. I have installed all the compulsory requirements (except CUDA since on this laptop I don't have a NVIDIA GPU). I installed the same GCC and set the path as suggested in the walkthrough page. Still I get the following error:

    Problem occurred during compilation with the command line below:

Any Suggestions?

This / \\ thing in

C:\Anaconda\libs/python27.lib:

sounds weird to me...

Answer 1

As suggested by Daniel in a comment, I did not run the command:

conda install mingw libpython

After that I was able to import Theano coerrectly. Solved! :)

Answer 2

Have you read this link?

Hope you find solution from that.
