## Title

    [PyTorch CUDA] "Found no NVIDIA driver on your system" / "The NVIDIA driver on your system is too old (found version N)"

## Body

    Cause (Documented platform behavior): cudaErrorInsufficientDriver with no driver version, or a driver version too old for the wheel's CUDA runtime; initialization errors when no GPU is usable.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - The NVIDIA driver on your system is too old (found version
    - CUDA driver initialization failed, you might not have a CUDA gpu.
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/pytorch/pytorch/4b0647edace7000cd959f43b857da716d06247c9/c10/cuda/CUDAFunctions.cpp (official_docs, unknown, documented_behavior): device_count error handling produces the no-driver, too-old-driver and initialization-failed messages.
    
    Search phrasings: Found no NVIDIA driver on your system docker; NVIDIA driver on your system is too old pytorch; torch cuda driver initialization failed
    
    Evidence basis (self-declared by the contributing chat client): public_source.
