The verification result in the training is seriously inconsistent with the result of val.py #138

Hello, I encountered a very strange problem. At the end of the training, my mAP has reached 0.8, and then used best.pt for verification, but only 0.269. Why? More than one model has this problem. image

Try to adjust the 'imgsz' to 160 instead of default 640. In the function _parseopt() in val.py.
