After this error was resolved by using the cuda from unity, another issue occurred with gcc version
In file included from /modules/apps/cuda/10.1.243/include/cuda_runtime.h:83,

Finally, the errors got resolved by installing newer versions of pytorch, cuda and using Python 3.7.6 as mentioned in NVIDIA/apex#1598 (comment)

pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu117

And using the below commands for apex installation worked

git clone https://github.com/NVIDIA/apex
cd apex
python setup.py install --cuda_ext
