Specific solutions:
1. Parameter configurationFile
The path here is suffixed with .txt

train: E:\VScode_Projects\yolov5-6.1\MyData\train.txtval: E:\VScode_Projects\yolov5-6.1\MyData\val.txt# train/val can either read the folder directly, or read the .txt file for indexing.# You use the .txt file index here, then you need to fill in the path to the .txt file level, just like now.# number of classesnc: 1# class namesnames: ["phothle"]

2. Add the following sentence to the cache on line 470 of the train.py file
