SSN and/or full temporal action localization pipeline support in mmaction2?

[henryrobbins]

Please excuse me if this is an ignorant question. I am new to this space. I am working on a project where I'd like to run a full temporal action localization pipeline. I understand most pipelines consist of extracting features (e.g. TSN, ID3), proposal generation (e.g. BSN, BMN), and finally action classification (e.g. SSN, P-GCN). I see that BSN and BMN are currently available on mmaction2 but it seems like SSN support was deprecated at some point (cc @Dai-Wenxun this commit?). Is that correct? If so, is there a suggested way to do this? Or will I need to go outside the mmaction2 framework to accomplish this?
