Windows - Error when import theano

[coroner4817]

When I try to import theano, it gives me this error:

My theanorc file has:

[global]
floatX=float32
device=gpu
mode=FAST_RUN

[blas]
ldflags=-LC:\\openBLAS -lopenblas

[cuda]
root = C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0

[nvcc]
compiler_bindir = C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin

I installed CUDA 7.0 and the GPU is GT540M. It's an old gpu but it should works. Can anyone help me with my case? THX!

Since you have spaces in some of your paths, maybe it will help to put quotation marks around them.

I have the same error Having quotation did not solve the problem on win 10. Could anyone help?

[coroner4817]

@masakinakada have you ever changed anything in your registry? In my case, I figured out that I have previously used registry to set the starting directory of the cmd to D drive using autorun. Remove that the error is fixed.

@coroner4817 Thank you very much Yingnan,

I do not recall I changed anything in the registry. Could you tell me which one might cause the error? I did not change it manually, but some of softwares might change it automatically...

Again, thank you so much!

@masakinakada Something like this: http://stackoverflow.com/a/4896002/4812471

Closing as we removed the old GPU back-end. Now we suggest to use pre-compiled conda packages for Theano and libgpuarray rather than trying to compile it with Visual Studio.

Thank you very much Yingnan and Pascal!
