Some (all?) demos do not work anymore on Google Colab.

/!\ Same happens with other mmcv packages

Some (all?) demos do not work anymore on Google Colab.

To reproduce: Open any demo in the demo folder, like this one.

Open in Google Colab and run the file. The third output cell is the following:

AssertionError                            Traceback (most recent call last)
<ipython-input-3-a857150f8e0e> in <cell line: 4>()
      2 from mmengine.utils.dl_utils import collect_env as collect_base_env
      3 
----> 4 import mmdet
      5 
      6 

/content/mmdetection/mmdet/__init__.py in <module>
     15 
     16 assert (mmcv_version >= digit_version(mmcv_minimum_version)
---> 17         and mmcv_version < digit_version(mmcv_maximum_version)), \
     18     f'MMCV=={mmcv.__version__} is used but incompatible. ' \
     19     f'Please install mmcv>={mmcv_minimum_version}, <{mmcv_maximum_version}.'

AssertionError: MMCV==2.2.0 is used but incompatible. Please install mmcv>=2.0.0rc4, <2.2.0.

This error does not match the !mim install "mmcv>=2.0.0rc4" of the cell above. I tried with changing the version of mmcv to one between 2.0.0rc4 & 2.2.0, but the same error keeps occurring.

same problems,

[antoineedy]

Same error as #3637

[thsimplt]

it works for me with :

Check nvcc version

!nvcc -V

Check GCC version

!gcc --version

!apt-get install -y gcc python-dev

Installer PyTorch avec pip

!pip install torch==1.12.0 torchvision==0.13.0 torchaudio==0.12.0

Install mim

!pip install -U openmim

Install mmengine

!mim install mmengine

Install MMCV

!mim install 'mmcv == 2.0.0rc4'

!rm -rf mmsegmentation !git clone -b main https://github.com/open-mmlab/mmsegmentation.git %cd mmsegmentation !pip install -e .

installing mmcv following the cmd does not work either

pip install mmcv==2.2.0 -f https://download.openmmlab.com/mmcv/dist/cu121/torch2.3/index.html

Instead, I install the mmsegmentation locally and change MMCV_MAX = '2.2.0' to MMCV_MAX = '2.2.1', and everything works fine.

Actually savior. Worked as well for me 🙌
