M5stickV V-training

[Min Han]

Encounter this error when training with detections. Labelled 115 images with Labelimg.py, and created the config files below:

classes.txt:
dog
lock

v-training.config:

{
"classes":2
}

I created a zip with the images, v-training.config,classes.txt in the same directory, which is also the only directory level in the zip i.e once u open the zip it opens to everything, according to the recommended template. The only thing I am missing is rename.bat, but theres no indication of what that is anywhere. Please advise.
