Please tell me how to extract features from training data

[kirorotarzan]

Excuse me, I need your help. I have modified a program based on a Streamlit application to run it as a command-line interface (CUI). As an additional process, I want to implement a feature where the extracted features of the training data images can be saved as data (or a model?) and then reloaded when the program is executed again. However, as I am a beginner, I am struggling to implement this properly. I would appreciate it if you could give me some advice. Thank you.

Hi, do you want to save the raw features (e.g. resnet50 features) or the features in the format of a specific approach? (e.g. spade features, padim features etc)

Thank you for your message. If possible, I would like to obtain the features of PatchCore. Best regards.

Excuse me. I've been doing some research, and is it correct to assume that I should use torch.save() to save the model?

Hey, over the weekend I started working on a .export method for spade and patchcore, but for patchcore it's only the torchscript that gets exported, not yet the onnx format. Need to take a further look at that.

check out the test_patchcore.py file for work so far

Thank you for your response and handling.
I have reviewed the code. Personally, if it is possible to save the model in a .pt file and load that .pt file for inference during the next program execution, then using .onnx files is not particularly necessary
