i had download the latest MMdetection-main and installed mmcv=2.0.0,but when i run the code ,it tell me issue like the title,i had tried to install mmcv-full=1.7.1 ,but it need run with mmcv.transformer and this model does not exsist in mmcv=full

Hi, @Latitude9527 works for me

torch.version
'1.9.0+cu111'
mmcv.version
'2.0.0rc4'
mmdet.version
'3.0.0'

# install mmengine
git clone https://github.com/open-mmlab/mmengine.git
cd mmengine
pip install -e . -v

# install torch https://pytorch.org/get-started/previous-versions/ 
# check torch version
python -c 'import torch;print(torch.__version__);print(torch.version.cuda)'

# install mmcv 
# pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
pip install mmcv==2.0.0rc4 -f https://download.openmmlab.com/mmcv/dist/cu111/torch1.9/index.html

# install mmdet
git clone https://github.com/open-mmlab/mmdetection.git
cd mmdetection
pip install -v -e .

# download checkpoint 
# check it works

Mine shows this error when running the second code to check for the torch version, could anyone help?

hi i have error: AssertionError: MMCV==2.0.1 is used but incompatible. Please install mmcv>=1.3.15, <1.8.0. i did above solution that kimlia545 said, but error did not solve

i run all the command above but in the last command it show stack trace. Is someone know this?

thanks！

I had to do this on Google Colab in order to mmdet to be installed successfully:

• downgrade pytorch: !pip install torch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 --index-url https://download.pytorch.org/whl/cu121

• install mim, mmengine, and mmcv like this:

!pip install -U openmim
!mim install mmengine
!mim install "mmcv>=2.1.0,<2.2.0"

• Install mmdetection like usual

!rm -rf mmdetection
!git clone https://github.com/open-mmlab/mmdetection.git
%cd mmdetection

!pip install -e .

• check the installation results:

# Check MMDetection installation
import mmdet
print("mmdetection:",mmdet.__version__)

# Check mmcv installation
import mmcv
print("mmcv:",mmcv.__version__)

# Check mmengine installation
import mmengine
print("mmengine:",mmengine.__version__)
