CUDA not detected means the software cannot find a working NVIDIA GPU or the required CUDA environment.

Solution steps:

  1. Verify hardware: Run nvidia-smi in Command Prompt. If it shows your GPU and driver version, proceed. If not, install the latest NVIDIA driver from nvidia.com.
  2. Install CUDA Toolkit 12.8+ (minimum required): Download from NVIDIA CUDA and install. After installation, confirm nvcc -V works.
  3. Install cuDNN 9.11+: Download from NVIDIA cuDNN and place the bin, lib, include folders into the CUDA installation directory (e.g., C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.8).
  4. Add environment variables: Ensure CUDA_PATH is set and %CUDA_PATH%\bin is in your system PATH.
  5. Restart pyVideoTrans after installation.

If you’ve done all this and still see the error, provide the latest 30 lines from logs/ folder for further diagnosis.
