I tried to install the latest version of

pyculib

, but got a problem. I used

conda install pyculib

in anaconda prompt and the installation runs successfully. But when I tried to

import pyculib

, the error occurs:

I have the same problem when trying to use

anaconda accelarate

.

Is this library missing in the latest version? I was able to use pyculib before. I can import pycuda and numba. I am using Anaconda3, python 3.6 on windows 10 pro.

I’m experiencing the same problem. Bump

3

os.environ[‘NUMBAPRO_CUDALIB’]=‘path/to/the/cudatoolkit/bin’

It works.

4

How would I go about applying that? I’m working with Windows 10.

5

You would issue that command in python, before you import numba or pyculib

6

It works for me. Thank you!

I tried typing

os.environ['NUMBAPRO_CUDALIB']='C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.2\bin'

in Anaconda Prompt and in Python code. Neither of those worked.

I’m not sure I understand what you mean by “issue that command in python.” I tried typing it in Python code and the Anaconda prompt and it didn’t work.
