How to save features extracted by the backbone

[cyj95]

I tried to save feature in ‘’anomalib/models/components/feature_extractors/feature_extractor.py‘’

but it displays that the feature shape is

it seems like in this part, feature hasn't been generated.
if i want to save the features extracted by the backbone,which python file should i edit?

You should call the print statement after _ = self.backbone(input_tensor) line (95). It is because hooks are added to the backbone and only when the forward function of the backbone is called, the features dictionary is populated.
