Maxwell Fix

[ghost]

Description

This PR fixes CUDA initialization issues on Maxwell GPUs by enforcing the correct PyTorch version (1.12.1+cu113) and adjusting requirements accordingly.
Also includes updated README instructions.

In modules/launch_utils.py, the following change was made:

Original lines (380-382):

if args.reinstall_torch or not is_installed("torch") or not is_installed("torchvision"):
    run(f'"{python}" -m {torch_command}', "Installing torch and torchvision", "Couldn't install torch", live=True)
    startup_timer.record("install torch")

were replaced with:

    if args.reinstall_torch or not is_installed("torch") or not is_installed("torchvision"):
    # Skipping automatic torch install; using manually installed torch 1.12.1 + cu113
     print("Skipping torch installation. Using existing torch 1.12.1 + cu113.")
    startup_timer.record("install torch")

[w-e-w]

this is not a valid code change, this is just instructions (which contains bogus code changes most likely an LLM)

assuming that it dose works on old GPUs (which I cannot verify) the proper way make a code change to add support would be to write some auto detection based on CUDA GPU Compute Capability and then dynamically switch which torch version it auto installs

• similar example #16972

on the other hand if someone wants to share instructions on how to use it on old GPUs, they should use custom TORCH_COMMAND TORCH_INDEX_URL environment variables which is the intended way of letting people configure custom torch version, not editing the code and breaking it for others
