Using SoftmaxCrossEntropyWithLogits function trainning loss chart as follows:
It should use CrossEntropyLoss function like this trend in pytorch:
It can be seen that the decrease in loss has become less significant, and the ability learned through testing has decreased.
This pr will maintain the code for SoftmaxCrossEntropyWithLogits function using on orangepi
experiment environment:
python 3.9.10
mindspore 2.5.0
