I. Error analysis

Running YOLOv5 github address: https://github.com/ultralytics/yolov5/

When executing YOLOv5's val.py

The console has a font warning

Open the generated file and find that the area that should display Chinese characters has become a box

Second, Resolve

Just add a sentence, perfect solution![This is set the Chinese font to italics]

Select after the import of plots.py under the utils package

Add the following code:

#Set the font to italicsimport matplotlibmatplotlib.rcParams['font.sans-serif'] = ['KaiTi']# If you want to set it to another font, just modify the font name directly
