cudatoolkit=11.1 -c conda-forge on Anaconda, but I keep getting an error

Question

I'm trying to install cudatoolkit=11.1 -c conda-forge on Anaconda, but I keep getting an error

conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=11.1 -c pytorch -c conda-forge

error message:

ERROR conda.core.link:_execute(740): An error occurred while installing package 'conda-forge::cudatoolkit-11.1.1-heb2d755_10'.

I tried uninstalling and reinstalling, but it didn't work, so I tried installing in a different virtual environment. I also searched extensively online, but I couldn't find any solutions for the same error code (execute(740)). I'm not sure how to configure it correctly.

cuda version is 11.1 cudnn is already installed
