The PyTorch example at for face landmarks 75 seems to suggest that training with that many target (in sets of two) is possible.
I have attempted to incorporate their working in order to set up my own dataset, but when I try to train, I just get:

RuntimeError: multi-target not supported

I am at a loss how one would train the dataset they’ve shown there. I would greatly appreciate any insight into how one may train this dataset, as it is directly applicable for my project.
