How to add a project to detectron2.projects

[amida47]

In order to add my project I created a fork of your repo .
I created a new directory for my project which is a backbone, inside the projects directory (not the one inside detectron2 folder)

this a screenshot of the files I created there is the parent directory BrainSeg-rcnn inside it there is brainSeg folder, inside this folder there is the files I created
in init.py

from .brainSeg import BrainSegBackbone
from .config import add_brainSeg_config

and in config.py

def add_brainSeg_config(cfg):
    cfg.MODEL.BACKBONE.NAME = 'BrainSegBackbone'
    
    cfg.MODEL.ANCHOR_GENERATOR.SIZES = [[2,4,8], [4,8,16], [8,16,32], [16,32,64]]
    cfg.MODEL.RPN.IN_FEATURES = ['level1','level2', 'level3', 'level4']
    cfg.MODEL.ROI_HEADS.IN_FEATURES = ['level1','level2', 'level3', 'level4']
    cfg.MODEL.PIXEL_MEAN= [0,0,0,0]
    cfg.MODEL.PIXEL_STD = [1,1,1,1]

I went then to detectron2 -> projects -> init.py and added brainSeg to the projects dict

_PROJECTS = {
    "point_rend": "PointRend",
    "deeplab": "DeepLab",
    "panoptic_deeplab": "Panoptic-DeepLab",
    "brainSeg" : "BrainSeg-rcnn"
}

and after installing detectron, with !python -m pip -q install 'git+https://github.com/amida47/detectron2' and running from detectron2.projects.brainSeg import * I get

ModuleNotFoundError                       Traceback (most recent call last)
[<ipython-input-3-b2834b7f750a>](https://localhost:8080/#) in <module>()
----> 1 from detectron2.projects.brainSeg import *
