So "pip install -e ." is the rebuild operation?

❓ So “pip install -e .” is the rebuild operation?

I see the Note in the Installation that said “you often need to rebuild detectron2 after reinstalling PyTorch.”, but there are multiple commands in that section, as

cd detectron2
pip install -e .

# or if you are on macOS
# MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ pip install -e .

# or, as an alternative to `pip install`, use
# python setup.py build develop

So my question is whether the “pip install -e .” is the rebuild operation other than any others?

Yes.

You’re right.
