Training YOLOv7-w6 model

Question

I'm trying to train the YOLOv7-w6 variation of YOLOv7.

This is the link to my Colab notebook.

I'm getting the following error message, and it cannot start training:

Answer 1

I cannot locate this error in your Colab file, have you solved the issue?
If you require Defect Detection, I would like to recommend an online demo for Anamoly Detection, which I found to be free and user-friendly. Additionally, it also had Yolo-v7 Detection which was also free and easy to use.
