I am trying to run this GitHub repository [faster rcnn-pytorch-custom-dataset](https://github.com/sovit-123/fasterrcnn-pytorch-training-pipeline#Train-on-Custom-Dataset) but I got this error.

```auto

Hello Abubakar,

Thank you for your patience and sorry this is happening to you. Could you please let me know;

What is your wandb cli version?  
Are there any other errors shown except these?  
Could you please share with me the `debug.log` and `debug-internal.log` files located in the working directory of the project under wandb//logs/?  
Are you running your script in jupyter notebook or terminal or through colab, etc.? Can I have an example training script of what you did exactly?

Thank you
