How to test the code on custom data?

[ParthKalkar]

I went through your codebase and it is excellently explaining the whole process, but I could not find how to test the model for custom images after training.

I was thinking to extend this project and use this model for a webapp. Therefore, I need to know how to test it for custom images?

Hi Parth,
I hope you're doing great!

Sorry for my late reply; got busy with university for a while and missed your issue.
Have you tried the infer.py file in the repo? I show there how to run the model for a single image.

Hi Moein,
It looks like there is some difference in keys in the saved model and model architecture. While using the infer file, I am getting the following error. Any thoughts on how to fix this?

model initialized with norm initialization

Load the ResNet weights as well. You have to train and save the weights.
