Torch.cuda.is_available() returns false while torch.backends.cudnn.enabled returns true

I;m using google colab and I have already checked and the hardware accelerator is set to GPU, but even so on my clouderizer when I try to run the torch.cuda.is_available() it returns false. I also changing the machine

I also tried changing the machine settings and checking on install CUDA 8.0, but it doesn’t change anything.

Looks like your NVIDIA driver install is corrupted. Check your NVIDIA driver. Does nvidia-smi look fine?


  1. change the machine to use CPU, wait for a few minutes, then change back to use GPU
  2. reinstall the GPU driver

Turns out, I had to uncheck the CUDA 8.0
