WARNING: non-finite loss, ending training tensor([nan, nan, nan, nan], device= cuda:0 )

This warning message typically indicates that the loss function has resulted in a non-finite or NaN (Not a Number) value during the training process. It could be caused by a variety of reasons such as incorrect hyperparameters, insufficient data or inappropriate data preprocessing, or even an issue with the model architecture.

To resolve this issue, you can try adjusting the learning rate or regularization parameters, increasing the size of your training dataset, or checking for any errors in your data preprocessing steps. Additionally, you can also try changing the architecture of your model or the optimization algorithm being used.

It is crucial to address this warning immediately as it could lead to inaccurate or unstable model predictions.
