I trained the model with Face_mask_detection and tested it on the Juptery Notebook. The test results were normal. But when I followed the tutorial and tested the model on the Jetson Nano, I either couldn’t detect a face or there were lots of red boxes on my face.I guess it might have something to do with classifier-threshold and class-attrs, but I can’t find any documentation about them.

Here is the doc Gst-nvinfer — DeepStream 5.1 Release documentation
