terms of settlement ： The label problem , I'm using voc Of xml label . stay labelimg Open the label and find that the upper right corner has been checked difficult This option , After removing it, save it and use it .

In fact, the image has no corresponding tag file , No load on labels file , So there's no way to calculate loss, You can see if there are any loaded into the corresponding image labels file

At this time , I'll be rude kill process , And then restart the program .

Here are some possible solutions ：

• RuntimeError: cannot perform reduction function

• Record the problems and solutions in the process of training deep learning algorithm .
