Im working on SSH linux server. Im not comfortable with linux environment. My problem looks like the environment is not ok, please how can setup correctly them? I want to use cupy with cahiner

Answer 1

for cuda 9.0:
pip install --pre cupy-cuda90
Or you may want to first do:
1. check you module list : module list
unload pgi module: module unload pgi/16.9
