I installed pytorch a few days ago and hit this error for the first time today ... so I don't think it's an installation problem... I also tried to reinstall pytorch and still get this error I am using torch 1.5.1+cu101 and python 3.8.5 on windows 10 I have only one version of python installed. if someone could please help me on this thanks a lot

I got a similar error with Python 3.9.2 on Windows 10 and solved it doing the following:

I copied the CUDA 11 drivers (specifically cublas64_11.dll) from:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.2\bin to C:\<your python directory>\Lib\site-packages\torch\lib

I was having the same problem which was solved by uninstalling all the versions of python and venv and reinstalling only one.
