Attempted to run the YoloV7 training colab without any modification:

https://colab.research.google.com/github/luxonis/depthai-ml-training/blob/master/colab-notebooks/YoloV7_training.ipynb#scrollTo=Z7rEpSboRibz

The first error occurred after running

Your help would be much appreciated!

Happy new year and holidays!

I had to edit the install string in several areas to account for the changing dependencies.

This was for the YOLOv6n training Colab page but it may help you.

I had to specify numpy==1.23.1.

My full updated install string is (currently ;) ):

!pip install -U -q torch==1.13.0 torchvision>=0.9.0 protobuf==3.19.5 numpy==1.23.1 opencv-python>=4.1.2 PyYAML>=5.3.1 scipy>=1.4.1 tqdm>=4.41.0 addict>=2.4.0 tensorboard==2.9.0 pycocotools>=2.0 onnx>=1.10.0 onnx-simplifier>=0.3.6 thop

It works thank you very much Deon!
