Chainer GPU #24

Open enzyme69 opened 7 years ago

enzyme69 commented 7 years ago

I am using Windows 7, Anaconda, whenever I install CUPY and try to run Chainer with GPU, it crashes. Any step by step tutorial on how to ensure GPU works? CPU is waaay... too slow. 1500 photos take whole day.

Hi, what is the message error ? I'm on Win10 with nvidia & cudnn & GTX 980 and everything works fine

Oh, I've been through that error. You have to install Microsoft Visual Studio and then CUDA. If it still doesn't work, you should tweak your environment PATH so that chainer can find cl.exe somethjng like C:\Program Files\Microsoft Visual Studio 10.0\VC\bin . However, maybe cl.exe can be found in another MS package, than Visual Studio, I don't know.

If it still doesn't work, try to use Miniconda2 (I use that).
