ImportError when importing PreProcessor

[MRaffl98]

Hi everyone,
I am getting a circular import problem when importing the PreProcessor (from anomalib.pre_processing import PreProcessor).

You can see the traceback here:

>>> from anomalib.pre_processing import PreProcessor
Traceback (most recent call last):
File "", line 1, in

from anomalib.pre_processing import PreProcessor
ImportError: cannot import name 'PreProcessor' from partially initialized module 'anomalib.pre_processing' (most likely due to a circular import) (/home/michael/anaconda3/envs/test/lib/python3.10/site-packages/anomalib/pre_processing/init.py)

I actually do not know why it attempts to import BTech from .btech.
Has anyone else experienced this issue?

As a workaround, the following works:

from anomalib.data.inference import InferenceDataset
from anomalib.pre_processing import PreProcessor

@RAM98AUT, thanks for letting us know!

Just an update that we will be deprecating PreProcessor class soon. It wraps the transforms, which add another layer of complexity. You will be able to use the transforms directly.

@samet-akcay, thanks for the update! That is good to know.
Great job by the way 😃
