ImportError cannot import name 'ball_query_ext' from 'mm3d_pn2.ops.ball_query' 急急急，在线等 about mvp_benchmark HOT 7 CLOSED

I think you should try to run "pip install -v -e . "
Do not miss the "."
And make sure you are in the right directory~

印象中，我没有遇到这个问题…
建议先按readme配置好环境。
如果没有解决，可以考虑把所有和 ball_query相关的语句都 注释掉，因为 VRCNet并没有 ball_query 操作。

非常感谢你的答复。这个问题我已经解决了，忘记执行这个命令了 pip install -v -e .

from mvp_benchmark.

can someone please explain this solution in english... I'm also having the same issue

from mvp_benchmark.

Please install the environment first, then you can try the code

from mvp_benchmark.

For the environment setup part, in the setup.sh file I've already run till the following lines:

conda create -n mvp python=3.7 -y
conda activate mvp
conda install pytorch==1.5.0 torchvision==0.6.0 cudatoolkit=10.1 -c pytorch -y

# setup completion
cd completion
pip install -r requirements.txt


cd ../utils/mm3d_pn2/
sh setup.sh

the only line I'm unable to run is
pip install -v -e
because I get an error saying : -e option requires 1 argument and also the above line is just for the SLURM users. So I guess I'm already done with the environment setup, But I still get this error.
