[Bug] How to use video or video frames to draw heat maps in version 1.x?
Branch
main branch (1.x version, such as v1.0.0, or dev-1.x branch)
Prerequisite
- [X] I have searched Issues and Discussions but cannot get the expected help.
- [X] I have read the documentation but cannot get the expected help.
- [X] The bug has not been fixed in the latest version.
Environment
I have all the required environments for version 2.1 installed.
Describe the bug
You also have the visual heat map code 'demo_gradcam.py' in mmaction2.0, but it seems to be missing in the demo after the update version mmaction2.1, but another 'gradcam_utils.py' in the utils file, which is not more convenient to do the heat map. Is there any solution? Or tell me how to use the heat map method of version mmaction2.1. Thank you very much for your answer!
