How to install torch in python
I tried pip3 install torch --no-cache-dir and, after few seconds, I got this:

What should I do now to install PyTorch?

I tried almost every method mentioned on google. I am working on Ubuntu, I tried using conda too, but I am unable to use that package outside conda.

For pip environment use this

pip3 install torchvision


For conda environment use this (run this command on anaconda prompt)

conda install PyTorch -c PyTorch




Update

Use this code to turn off your cache

pip3 --no-cache-dir install torchvision


or

pip3 install torchvision--no-cache-dir


or

pip install --no-cache-dir torchvision


Try one by one
