I have this problem when I use mmsegmentation, do you know why, thanks！！

We recommend using English or English & Chinese for issues so that we could have broader discussion.

Hi @endaoguansanlu, It seems that mmcv-full is not properly installed, you could try to reinstall mmcv-full with the following command.

pip uninstall mmcv
pip install openmim
mim install mmcv-full

Thank you very much for your selfless help. Currently this problem has been solved, but I have this problem when importing build_segmentor, do you know how to solve it? thank you very much！！！ Traceback (most recent call last): File "e:/MyModel/train.py", line 15, in from mmsegmentation.mmseg.models import build_segmentor File "e:\MyModel\mmsegmentation\mmseg\models__init.py", line 2, in from .backbones import * # noqa: F401,F403 File "e:\MyModel\mmsegmentation\mmseg\models\backbones__init__.py", line 2, in from .beit import BEiT File "e:\MyModel\mmsegmentation\mmseg\models\backbones\beit.py", line 17, in from ..builder import BACKBONES File "e:\MyModel\mmsegmentation\mmseg\models\builder.py", line 8, in MODELS = Registry('models', parent=MMCV_MODELS) File "D:\Python\lib\site-packages\mmcv\utils\registry.py", line 127, in init__ parent._add_children(self) File "D:\Python\lib\site-packages\mmcv\utils\registry.py", line 254, in _add_children f'scope {registry.scope} exists in {self.name} registry' AssertionError: scope mmseg exists in model registry

Could you show the codes you modified if possible? The scope is usually registered only once.

Another potential reason: Sometimes this error happens when certain libaries installation are not complete, or certain libaries are overlapped or destroyed thus they can not be imported and program does not know corresponding libaries.

I met this error before and it happened in PIL, so I suggest you go through your environment packages to check whether they are correct, you could locate your wrong library and uninstall & install it like below:

First

pip uninstall Pillow

And then

pip install Pillow
