Hey Did you get any solution for it

[Matteo-Frattaroli]

@bankyresearch @AryamanGurjar apparently they moved around the files or modified some init files.

This should work:
lp.models.detectron2.Detectron2LayoutModel

Unluckily even though I resolved the AttributeError, i ran into another issue:

----> 1 model = lp.models.detectron2.Detectron2LayoutModel('lp://PubLayNet/faster_rcnn_R_50_FPN_3x/config',
2 extra_config=["MODEL.ROI_HEADS.SCORE_THRESH_TEST", 0.8],
3 label_map={0: "text", 1: "title", 2: "list", 3:"table", 4:"figure"})

File /usr/local/lib/python3.10/dist-packages/layoutparser/models/base_layoutmodel.py:87, in BaseLayoutModel.new(cls, *args, **kwargs)
85 def new(cls, *args, **kwargs):
---> 87 requires_backends(cls, cls.DEPENDENCIES)
88 return super().new(cls)

File /usr/local/lib/python3.10/dist-packages/layoutparser/file_utils.py:175, in requires_backends(obj, backends)
173 name = obj.name if hasattr(obj, "name") else obj.class.name
174 if not all(BACKENDS_MAPPING[backend]0 for backend in backends):
--> 175 raise ImportError(
176 "".join([BACKENDS_MAPPING[backend][1].format(name) for backend in backends])
177 )

ImportError:
Detectron2LayoutModel requires the detectron2 library but it was not found in your environment. Checkout the instructions on the
installation page: https://github.com/facebookresearch/detectron2/blob/master/INSTALL.md and follow the ones
that match your environment. Typically the following would work for MacOS or Linux CPU machines:
pip install 'git+https://github.com/facebookresearch/detectron2.git@v0.4#egg=detectron2'

Of course i installed detectron both as suggested by the error message and as actually indicated in the repo's readme file but with no success. I keep getting the same error.
