How sam2_configs pushed in the {sys.path} in python?

[aza1200]

By the segment-anything-2/INSTALL.md's comment

It says that

---

I got `MissingConfigException: Cannot find primary config 'sam2_hiera_l.yaml'`

This is usually because you haven't run the pip install -e . step above, so sam2_configs isn't in your Python's sys.path. Please run this installation step. In case it still fails after the installation step, you may try manually adding the root of this repo to PYTHONPATH via

export SAM2_REPO_ROOT=/path/to/segment-anything  # path to this repo
export PYTHONPATH="${SAM2_REPO_ROOT}:${PYTHONPATH}"

to manually add sam2_configs into your Python's sys.path.

But I can't find out
how sam2_configs are inserted by executing

pip install -e .

I know that acting means python setup.py
But in that file there is no indication that insert python.syspath

Hi @aza1200, do you encounter any failures after pip install -e . (or manually adding the repo root to PYTHONPATH) as in https://github.com/facebookresearch/segment-anything-2/blob/main/INSTALL.md?

Please reopen or create a new issue if you encounter failures with this step.

Regarding pip install -e ., it would usually create a link to the SAM 2 repo path (in my environment, it adds a link in my Anaconda environment at
~/anaconda3/envs/base/lib/python3.10/site-packages/__editable__.SAM_2-1.0.pth) to allow editable installations. See details in https://setuptools.pypa.io/en/latest/userguide/development_mode.html and pypa/setuptools#3548.
