I have remote access via SSH to a user(not root) in an NVIDIA Tesla A100 40GB which i want to use for training purposes. For which i require to use pytorch enabled CUDA.  I am using conda for installing it in a virtual env .The nvidia-smi on the device shows:

NVIDIA-SMI 450.142.00   Driver Version: 450.142.00   CUDA Version: 11.0

So i tried to install first pytorch for cuda with following command i found on the pytorch website

conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=11.0 -c pytorch

But it returned torch.cuda.is_available() to be false. Same was the case when i tried to install cuda 10.2 or cuda 11.1 with commands available on the website here but still returned to be false.
If i run the command

/usr/local/cuda-11.0$ cat version.txt

i get the output as follows: - CUDA Version 11.0.207
And if i run the command

dpkg -l | grep cuda-toolkit

I get the output as :-

rc  cuda-toolkit-11-3                          11.3.1-1                              amd64        CUDA Toolkit 11.3 meta-package

Please help!
