The test result class is empty？
Hi @Gigi_Dai - it doesn’t look like it is “empty,” but rather an issue with the parsing of the class names when the training code read the images/annotation files for training.
Are they written in Cyrillic script or with symbols other than punctuation marks? Labels aren’t compatible for those characters with the underlying model.
If they are, then you can use our Modify Classes tool to adjust the labels
