CUDA not detected on Windows

1

Apologies for a simple question. I have installed Torch on Windows 10.

Torch has Cuda .
print( torch.version)
2.7.0+cu118

Cuda also seems to be available on my computer.
nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2022 NVIDIA Corporation
Built on Tue_May__3_19:00:59_Pacific_Daylight_Time_2022
Cuda compilation tools, release 11.7, V11.7.64
Build cuda_11.7.r11.7/compiler.31294372_0

But:
print(torch.cuda.is_available() )
False

This is a new install of both Conda and Torch.

Any help would be appreciated.

Hello @Hector

This error could be due to your NVIDIA GPU not being able to support the CUDA 11.8 version, since you installed PyTorch with CUDA 11.8 support (2.7.0+cu118).

Perhaps you can check which CUDA version does your GPU support, by matching your GPU’s compute capability, microarchitecture and supported CUDA SDK using these tables.
