RuntimeError: nms_impl: implementation for device cuda:0 not found.

This error occurs when the Non-Maximum Suppression (NMS) implementation is not found for the specified CUDA device.

Possible reasons for this error include:

1. The CUDA device is not available or has not been properly configured.
2. The NMS implementation is not compatible with the specified CUDA device.
3. There is a problem with the installation of the necessary software components, such as PyTorch or CUDA.

To resolve this error, you can try the following steps:

1. Check that the CUDA device is properly configured and available for use.
2. Verify that the NMS implementation is compatible with the specified CUDA device.
3. Reinstall the necessary software components and ensure that they are properly configured.

If the error persists, you may need to seek further assistance or consult the documentation for the software you are using.
