vis_cam.py in mmsegmenation

[yuanyuangoo]

Can we have a grad-cam-like tool to visualize feature maps, like in vis_cam.py in misclassification?

of course, we have supported very powerful visualization tool in mmseg 1.0.0rc0, you can try it

Thanks for the response. How do I get a feat-map of a certain layer after I trained a model using mmsegmentation and got weights?

Just save any tensor map like below as you want, then load it ant see it with the visualization tool.
