multi-label bug and some questions

[kingvision]

HI:
i have some questions:
1 in the convert_imageset_multi_label.cpp line 164
const std::string& data_label = datum_label.data();
I think the "datum_label" maybe " datum_image".

2	       How do you prepare the samples?

3       Which a few attributes are used to predict?

4	        How to train? If join face key points

thanks

Thanks
1, It should be "datum_image" instead of "data_image" in line 168.
2, I will update some samples, My preparing code will coming soon.
3, I use celebA database to train, use all the 40 attributes
4, I'm doing this now, I'm not sure my idea is working, So ...
