error: Multiple top-level packages discovered in a flat-layout: ['demo', 'configs', 'opendet2', 'datasets', 'detectron2'].

When I followed the README to install opendet2, I got some trouble. Here is my command. I have several rtx3090 gpus.

# CUDA V11.1
# torch 1.9.0
# python 3.8
conda create -n opendet2 python=3.8 -y
conda activate opendet2
# get pytorch 1.9.0. I got RuntimeError: CUDA error: device-side assert triggered when using torch 1.8.1
pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.html
# build opencv
pip install opencv-python
pip install opencv-contrib-python
# build detectron2. DO NOT build detectron2 from latest SOURCE. In the latest version, some named methods have been removed.
pip install detectron2==0.5 -f https://dl.fbaipublicfiles.com/detectron2/wheels/cu111/torch1.9/index.html
# build opendet2
cd opendet2
pip install -v -e .

When I run the last command pip install -v -e ., I got these error message:

(opendet2) yupeng@ubuntu:~/opendet/opendet2$ pip install -v -e .

    To avoid accidental inclusion of unwanted files or directories,
    setuptools will not proceed with this build.

    If you are trying to create a single distribution with multiple packages
    on purpose, you should not rely on automatic discovery.
    Instead, consider the following options:

    1. set up custom discovery (`find` directive with `include` or `exclude`)
    2. use a `src-layout`
    3. explicitly set `py_modules` or `packages` with a list of names

    To find more information, look for "package discovery" on setuptools docs.

I could use pip install setuptools==58.2.0 and retry pip install -v -e ., then everything is fine. It seems there are some problems by using the lateset setuptools>=61.0. Maybe you can find more information in the link below: https://github.com/pypa/setuptools/issues/3197 https://github.com/pypa/setuptools/issues/3227 https://github.com/facebookresearch/detectron2/issues/3943 https://github.com/facebookresearch/detectron2/issues/3811 Good luck.

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

I can solve this by using pip install protobuf==3.20.1
