Description
I have searched related issues and tried to do the implementation with no success.
I am aiming to split a spatio-temporal action detection model into two configuration files. Base and Head
A configuration for the backbone (type=fastrcnn) and a configuration for roi_head. This will help me to export the backbone into onnx.
The problem is, I can't load the model from the config once I changed the configuration. Is there an example to follow. As every time I want to load base or head I get errors thrown
