Therefore, using pip is your actual problem, because pip installed pytorch can be expected to need exactly the right version, else the dependencies can fail.


In case “need exactly the right version” refers to a local CUDA toolkit, then it’s wrong.
The pip wheels statically link the CUDA runtime and don’t need a local CUDA toolkit same as the conda binaries. The difference between these two is the way to statically link (pip wheels) vs. dynamically link (conda binaries) the CUDA runtime.
