how to solve this？

wuhuikai commented 5 years ago

Do you have an Nvidia GPU card and install the driver and the corresponding cuda lib?

Northzhangmingzhe commented 5 years ago

I have GPU and the driver, but I install pytorch 1.0.0 by conda

wuhuikai commented 5 years ago

It seems like that it's caused by the wrong configuration of the environment variables like PATH. As a result, nvcc can not be found correctly.
