Expected behaviour

• I ran the exact same sequence of commands on Google Colab and was able to compile multiple models (padim & cflow) and achieve various inferences from the trained model.
• Command run:

!python tools/train.py --config anomalib/models/padim/config.yaml

ERROR response when running training command:

Hardware and Software Configuration

• GOOGLE COLAB
• Python 3 Google Compute Engine backend (GPU)
• [standard Colab account specs as of 2022-10-19]

Additional context

• The suggested fix is to install an older version “omegaconf==2.0.0”, however, this leads to a new error.

@ANTZ314, this is probably due to one of our recent PRs #637. I’ll check the notebooks and fix them if needed.

[samet-akcay]

@ANTZ314, @JACKYNIKK, the problem is that the jupyter notebook installs anomalib via pip, which installs v0.3.6 now. You clone the repo via !git clone https://github.com/openvinotoolkit/anomalib.git, which clones the latest commit, and causes conflict with the pypi version.

Solution For now, if you clone and install anomalib as the following, the problem would temporarily be resolved.

Option - 1 Train the model via

!python tools/train.py --model padim

Option - 2 Install the library locally

!git clone https://github.com/openvinotoolkit/anomalib.git
%cd anomalib
!pip install -e .

We’ll soon update the pypi version with v0.3.7, which would remedy this issue completely.
