def get(config_path, trained: bool = False):
"""
Get a model specified by relative path under FsDet's official ``configs/`` directory.
Args:
config_path (str): config file name relative to FsDet's "configs/"
directory, e.g., "COCO-detection/faster_rcnn_R_101_FPN_ft_all_1shot.yaml"
trained (bool): If True, will initialize the model with the trained model zoo weights.
If False, the checkpoint specified in the config file's ``MODEL.WEIGHTS`` is used
instead; this will typically (though not always) initialize a subset of weights using
an ImageNet pre-trained model, while randomly initializing the other weights.
Example:
.. code-block:: python
from fsdet import model_zoo
model = model_zoo.get("COCO-detection/faster_rcnn_R_101_FPN_ft_all_1shot.yaml", trained=True)
