It looks like the loss in the call self.log_metrics (epoch, accuracy, loss, data_load_time, step_time) is the criterion itself (CrossEntropyLoss object), not the result of calling it. Your training loop needs to call the criterion to compute the loss, I don't see it in the code your provided. I missed that out while copying the code ...
