Reproduces the problem - command or script

FIrstly, Install the thirdpart project Open-CD:
https://github.com/likyoo/open-cd/blob/main/docs/install.md

conda create -n opencd python=3.8
# install pytorch 1.13.1
pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu117
# Install OpenMMLab Toolkits as Python packages
pip install -U openmim
mim install mmengine==0.10.4
mim install mmcv==2.1.0
mim install mmpretrain==1.2.0
pip install mmsegmentation==1.2.2
pip install mmdet==3.3.0
git clone https://github.com/likyoo/open-cd.git
cd open-cd
pip install -v -e .
pip install ftfy
pip install regex

Secondly, do some infer testing:
https://github.com/likyoo/open-cd/blob/mocs/inference.mdain/docs/inference.md

>>> from opencd.apis import OpenCDInferencer
>>> # Load models into memory
>>> inferencer = OpenCDInferencer(model='changer_ex_r18_512x512_40k_levircd.py', weights='ChangerEx_r18-512x512_40k_levircd_20221223_120511.pth', classes=('unchanged', 'changed'), palette=[[0, 0, 0], [255, 255, 255]])
>>> # Inference
>>> inferencer([['demo_A.png', 'demo_B.png']], show=False, out_dir='OUTPUT_PATH')

Additional information

How can I let the opencd work if I can't modify the MODULE2PACKAGE?
or there is any other method can I do to bypass the assert check?

Hi @zhanzf, please try to specify the correct path to the model file (and weights file), because otherwise you end up in this else which throws the error. But even if one would add opencd to MODULE2PACKAGE, it would fail later because self._load_model_from_metafile(model) assumes a certain layout, e.g. it needs model-index.yml (see e.g. mmsegmentation) which open-cd does not have.

Other option is to monkeypatch MODULE2PACKAGE - it's an ugly hack, but there is nothing which can't be done in python ;)
