TypeError: must be real number, not str with evolve #566
Description
Hi, thanks for this amazing repo first of all!
I am working with the v2.0 release of the repo and so far I got quite promising results on my custom dataset. I tried to use --evolve today but I am getting a TypeError from the print_mutation function in utils.py at the end of the first run. It seems to be related to 'SGD' in hyp dictionary - which is a string. I see that the optimizer parameter was added to the dict in v2.0 so I guess this wasn't an issue in the previous release.
Input:
!python yolov5/train.py --img 512 --batch 16 --epochs 100 --yolov5/data/custom_data.yaml \
--cfg yolov5/models/custom_yolov5s.yaml \
--weights yolov5/weights/yolov5s.pt --cache --evolve
Output:
Traceback (most recent call last):
File "yolov5/train.py", line 516, in <module>
