No module named 'numpy.typing' error

[daeheepark]

At first, thank you for amazing code release!

I followed the instruction in README, but faced ModuleNotFoundError: No module named 'numpy.typing'.

I found that numpy version 1.19.5 is to be installed in "mmdetection3d-0.17.3/.github/workflows/build.yml".

However, as I know, numpy.typing is introduced after numpy version 1.20 (https://stackoverflow.com/questions/67117848/a-question-about-modulenotfounderror-no-module-named-numpy-typing).

In addition, when i upgrade the numpy to version 1.20.3, I get ImportError: cannot import name 'NDArray' from 'numpy.typing'.

Which version should I upgrade for numpy?

You can try upgrading numpy to 1.23.4.
