KeyError: u'Non-existent config key: MRCNN.BBOX2MASK'

[mengyuest]

I was trying to test the inference section. My computer is Ubuntu16.04 with 1080TI (CUDA9.0 + CUDNN7.1). The installation of Caffe2 and Detectron all seemed work (no error in test, except some warnings). Then I ran

python2 tools/infer_simple.py \
    --cfg configs/bbox2mask_vg/eval_sw/runtest_clsbox_2_layer_mlp_nograd.yaml \
    --output-dir /tmp/detectron-visualizations-vg3k \
    --image-ext jpg \
    --thresh 0.5 --use-vg3k \
    --wts lib/datasets/data/trained_models/33241332_model_final_coco2vg3k_seg.pkl \
    demo_vg3k

It aborted with error KeyError: u'Non-existent config key: MRCNN.BBOX2MASK' . Followed is the full logging.

I checked with some similar errors online, which is about "indentation mismatch", but seems not our case. Anyone knows how to solve this, and does the warning information matter? Thanks.

Hi, from your error message, it seems that you are using your existing Detectron installation (/home/meng/lab-mill/Detectron) instead the modified Detectron codebase contained in this repo.

This repo has a modified config file (lib/core/config.py) that is different from the default Detection codebase released by FAIR, causing the error above. It's necessary that this repo comes before your existing installation in your python path (You can use import sys; print(sys.path) to see your python path). Running cd ./lib && make in this repo may resolve the issue.

Great cd ./lib && make perfectly works. Thanks for the help.
