RuntimeError: CUDA error: device-side assert triggered

This error occurs when a CUDA device-side assert is triggered, indicating that an assertion in the CUDA code has failed. This can happen for several reasons, such as invalid input data or a programming error in the CUDA code.

To debug this error, you can try the following steps:
1. Check the input data to make sure it is valid and within the expected range.
2. Verify that the CUDA code is correct and does not contain any programming errors.
3. Enable CUDA error checking by adding the following code at the beginning of your program:

import torch
torch.backends.cudnn.benchmark = True
torch.backends.cudnn.enabled = True
torch.backends.cudnn.deterministic = True
torch.autograd.set_detect_anomaly(True)

4. If the error persists, try running the code on a different CUDA-enabled device to see if the issue is specific to the current device.

If you are unable to resolve the error, you can seek help from the CUDA community or the library or framework documentation you are using.
