Installing NVIDIA CUDA Toolkit for Deep Live Cam (Absolute Beginners)
Installing NVIDIA CUDA Toolkit for Deep Live Cam (Absolute Beginners) If you launch Deep Live Cam and the console immediately prints `Execution provider: CPU` despite you owning a $1,000 Nvidia Graphics Card, you have failed to install the neurological pathways necessary for AI to communicate with your hardware. To unlock the immense power of your GPU, you must manually install the NVIDIA CUDA Toolkit. This alienates many beginners, but the process is highly systematic. The Version Matching Protocol The most common fatal error is installing the *newest* CUDA toolkit. Python packages like `onnxruntime` are highly stubborn. If your Deep Live Cam repository requires `CUDA 11.8`, and you install `CUDA 12.3` because it was the newest button on Nvidia's website, the software will crash entirely. Always inspect the `requirements.txt` file within the repository. It will dictate the exact sub-version required. The Crucial Role of cuDNN...
