Precious and recall are 0

[GreenHandForCoding]

使用的数据集是我在yolov5使用过的，在yolor中训练时很多参数都为0

Can you give more info? It could take some time before the model actually starts learning. Max I've had was around 10 epochs before it started.

I also have this problem.

You need to change "class" and "filter" parameter in cfg file. filter = (number of class + 5)*3

What @nhatanh174 said is indeed very important- but it could also be that your model just has a lot to learn and can take some time to do this. wait for 20 epochs and if nothing changes with the precision and recall you could look for other issues :) Also be sure that input size is somewhat near the "img_size" given to the model. I've observed that a lot of stretching/rescaling is very non beneficial to the training performance.
