Got very high recall but low precision in my own two-classes dataset #403

Hi, I tried to train the original yolov4 model on my own datasets. Why I will got a model with very high recall but very low precision? , It seems like my model can locate the object but cannot classify the objects correctly.

I can promise the dataset is correct because I have tested it using darknet.

By the way, I observed that the cls loss is very low at the beginning of my training, it is only 0.0016 in the first epoch. Anyone can tell me it is normal?

For testing the code, I use the only one dataset as the training dataset and the valid dataset
