When trying to extract visual features using VQA maskrcnn benchmark: files · master · vedanuj Goswami/VQA maskrcnn benchmark · gitlab,

After compiling maskrcnn benchmark according to the instructions of install, run

python script/extract_features.py ... 

An error occurred:

KeyError "Non-existent config key: MODEL.BACKBONE.OUT_CHANNELS"

The problem is: instead of compiling maskrcnn benchmark, you can compile setup.py under VQA maskrcnn benchmark

PS: the author has made corresponding fine adjustments to the network structure and code. The structure in the original maskrcnn library does not correspond to config
