Instructions To Reproduce the Issue:

Check https://stackoverflow.com/help/minimal-reproducible-example for how to ask good questions.
Simplify the steps to reproduce the issue using suggestions from the above link, and provide them below:

1. Full runnable code or full changes you made:

If making changes to the project itself, please use output of the following command:
git rev-parse HEAD; git diff

<put code or diff here>

2. What exact command you run:
3. Full logs or other relevant observations:

Config '/home/ubuntu/feature_extraction/py-bottom-up-attention/configs/VG-Detection/faster_rcnn_R_101_C4_attr_caffemaxpool.yaml' has no VERSION. Assuming it to be compatible with latest v2.

Expected behavior:

If there are no obvious crash in "full logs" provided above,
please tell us the expected behavior.

If you expect a model to converge / work better, we do not help with such issues, unless
a model fails to reproduce the results in detectron2 model zoo, or proves existence of bugs.

Environment:

Paste the output of the following command:

Hi @yanchuqiao,
cfg.set_new_allowed(True)
Add the above code element, and it should solve the issue...
