Installing cuDNN (add <installpath> to the Include Directories...) #42

Open erikodo opened 8 years ago

erikodo commented 8 years ago

How can I complete the second step in the installation of cuDNN?

In your Visual Studio project properties, add to the Include Directories and Library Directories lists and add cudnn.lib to Linker->Input->Additional Dependencies.

Here's what it looks like without this step:

`C:\Python27\cudarray>python setup.py install C:\Python27\lib\site-packages\setuptools\dist.py:285: UserWarning: Normalizing '0.1.dev' to '0.1.dev0' normalized_version, running install

Visual C++ for Python is only available as a command prompt. Can I do something with the command prompt, or do I need a new version visual studio? I'm not sure how to proceed.

Thanks.

I have the exact same error.

I think the issue may stem from improperly defined environment variables, but I'm not sure.

Installing cudarray without the CUDA backend worked, as I understand it uses numpy instead. However when I run programs which rely on cudarray Python crashes, so I am interested in getting this set up as designed.

Hi there! Can you try to change this line from

extra_compile_args = ['-O3', '-fPIC', '-Wall', '-Wfatal-errors']

to

extra_compile_args = ['-O3', '-fPIC', '-Wall']

You can also try to remove more flags. I'm not completely sure what Visual C++ is unhappy about.

hello, I have the same problem. Have you found the solution?
