I have sucessifully trained the mask r-cnn,and I want to visualize the feature maps in FPN and Res50,but I have no ideas.Did anyone have done this?thanks!

Hi @CPFelix, the easiest may be to (1) save intermediate features for images you care about to disk (e.g. in pkl format; see #123 for how to extract feature blobs) and (2) write a tool or notebook that visualizes the pre-computed features.
