RuntimeError: No CUDA GPUs are available

This error message is generated when the program tries to use the CUDA library for GPU acceleration, but no compatible GPU device is found. This can happen if there is no GPU installed in the system, or if the GPU drivers are not properly installed or configured.

To address this issue, you can try the following steps:

1. Check if your system has a compatible GPU installed. You can check the specifications of your system or contact the manufacturer to confirm this.

2. Make sure that the GPU drivers are up to date and properly installed. You can download the latest drivers from the GPU manufacturer's website and follow the installation instructions.

3. Check if CUDA is properly configured. You can check the CUDA version and other configuration settings by running the `nvidia-smi` command in the terminal.

4. If you are using a virtual environment, make sure that CUDA is installed in the environment and that the environment is properly activated before running the program.

5. If none of the above steps work, you can try running the program on a different system with a compatible GPU or using a CPU-only version of the program.
