make sure repo package python-pip is installed on system. If you are doing the Nvidia gpu also install python-pytorch-cuda from the arch repos. Other than that You should be able to follow the installations directions on here. as far as installing unity editor, well you are just looking for how to get and install unity-editor for linux :D hope that helps.
