mmdet depends on mmcv>=2.0.0rc4 while mmtrack depends on mmcv <2.0.0

Checklist

1. I have searched related issues but cannot get the expected help.
2. The bug has not been fixed in the latest version.

Describe the bug mmcv versions are not compatible between mmdet and mmtrack. From the assertion errors,

• mmdet depends on mmcv>=2.0.0rc4, <2.2.0
• mmtrack depends on mmcv>=1.3.17, <2.0.0

Resolving the mmcv version of mmtrack means that the repo is not compatible with mmdet, and vice versa.

Reproduction

1. What command or script did you run? In demo/MMTracking_Tutorial.ipynb, I ran:

# Check Pytorch installation
import torch, torchvision
print(torch.__version__, torch.cuda.is_available())

# Check mmcv installation
from mmcv.ops import get_compiling_cuda_version, get_compiler_version
print(get_compiling_cuda_version())
print(get_compiler_version())

# Check MMDetection installation
import mmdet
print(mmdet.__version__)

# Check MMTracking installation
import mmtrack
print(mmtrack.__version__)

2. Did you make any modifications on the code or config? Did you understand what you have modified? No modifications made. No dataset has been used.

Environment

1. Please run python mmtrack/utils/collect_env.py to collect necessary environment information and paste it here.
2. You may add addition that may be helpful for locating the problem, such as
   • How you installed PyTorch [e.g., pip, conda, source]
   • Other environment variables that may be related (such as $PATH, $LD_LIBRARY_PATH, $PYTHONPATH, etc.)

I used the provided Dockerfile to spin up a container to run this.

[rastna12]

I was able to get the Dockerfile to build a working image by replacing RUN pip install mmdet with RUN pip install 'mmdet<3.0.0' in the Dockerfile and also adding the missing mmengine package with adding RUN pip install mmengine.
