how to set the CUDA path to environment variable `CUDA_PATH'

Hello,

Im new using cupy and anaconda in linux. So im afraid to make any error in environment system.

I install cupy using the following and the installation was ok: source activate testing-env conda install -n testing-env cupy

Downloading and Extracting Packages cudnn 7.1.2: ######################################################################## | 100% cupy 4.0.0: ############################################ | 100% nccl 1.3.5:############################################################# | 100% fastrlock 0.3:############################################################ | 100%

Preparing transaction: done Verifying transaction: done Executing transaction: done

in my script I test the installation fisrtly: import cupy as cp print ‘test’

output: test

but when i modify the script to be: import numpy import cupy as cp x = cp.arange(6).reshape(2, 3).astype(‘f’) print x

i get the following:

Can you please help on how to set the cuda variable?

@kmaehashi i can confirm it is working. Thank you so much

@kmaehashi

Correct me please if it is like that i should set the variable :

export CUDA_PATH=/cvmfs/soft.computecanada.ca/easybuild/software/2017/avx2/Compiler/gcc5.4/cuda/9.0.176
export PATH=/cvmfs/soft.computecanada.ca/easybuild/software/2017/avx2/Compiler/gcc5.4/cuda/9.0.176/bin:$PATH
