Extract latent representation information?

[chuanenlin]

From Fig. 9, 10, 11 of the paper, I saw that clustering visualizes the latent spaces distributions (view, skeleton, motion).
I am wondering if it is possible to output the latent space data (e.g., camera-view angle in degrees of the subject for a specific frame)?

Hi, there are functions to visualize latent codes in cluster.py. You can look into that code for your own need.

Thanks for the reply.

I tried running python cluster.py -n view to test and received the following error:
line 126, in get_cluster_data all_data = torch.stack(all_data, dim=0) RuntimeError: expected a non-empty list of Tensors

Does this mean I first need to download the Mixamo dataset as described in mixamo_download_script.java, and if so, may I ask where should the .fbx files be saved and are there any specific formatting (e.g., of directory names) required?

Yes, you miss the data. But there is no need to download the original fbx, we provide processed data for direct usage.
