hello i have recently started using pytorch but now i need to use my GPU which is a Nvidia GTX 1050ti to process some data but unfortunately torch.cuda.is_available() is returning False i have tried uninstaling cudatoolkit 11.3 and downgrade it to 11.1 and also deleating and reinstaling pytorch using conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c nvidia -c conda-forge, here’s some information about my local configuration :
OS : windows 10 
graphical card : nvidia 1050ti
current nvidia driver : 465.89

>>> torch.version.cuda
'11.1'
>>> torch.cuda.is_available()
False
>>> torch.backends.cudnn.enabled
True
>>> torch.__version__
'1.8.1'

   ->   nvcc --version
