I installed Anaconda, CUDA, and PyTorch today, and I can't access my GPU (RTX 2070) in torch. I followed all of installation steps and PyTorch works fine otherwise, but when I try to access the GPU either in shell or in script I get >>> import torch >>> torch.cuda.is_available() False >>> torch.cuda.device_count() 0 >>> print(torch.version.cuda) None Running conda list shows this as my installed package cudatoolkit 11.3.1 h59b6b97_2 and running numba -s in the conda environment shows __CUDA Information__ CUDA Device Initialized : True CUDA Driver Version : 11030 CUDA Detect Output: Found 1 CUDA devices id 0 b'NVIDIA GeForce RTX 2070' [SUPPORTED] compute capability: 7.5 pci device id: 0 pci bus id: 1 Summary: 1/1 devices are supported and all of the tests pass with ok. CUDA 11.3 is one of the supported compute platforms for PyTorch and by my GPU and that is the version that I installed. I already tried reinstalling CUDA, I am on Windows 10, nvcc --version shows that CUDA is installed Build cuda_11.3.r11.3/compiler.29745058_0 Any suggestions would be helpful Edit: I am using PyTorch 1.10 installed from the generated command on their website. Using python 3.9.7. I also installed PyTorch again in a fresh conda environment and got the same problem. Continue reading...
