gpgraph's Issues

Code for other baseline models

Hi, thanks for the nice work!

In the repo, you only provide the code for SGCN. I am wondering whether you could also add the code for other baseline models in your table1. Also, could you provide the code for evaluating the PW and GW for your model, as is shown in table2? Thanks!

Trajectory visualization

Hello, may I ask how the pedestrian trajectory visualization in the paper is realized?

version problem

What are the versions of cuda and pytorch you are using, and I did not find your requirements.tx. Thank you very much if you can share it！

Can the modules for group and pedestrian interaction in the code be used independently?

I am currently trying to implement a crowd grouping algorithm, and I was greatly inspired by your work. I would like to ask if the code for row-to-row group interaction can be used alone without the prediction part.

visualize trajectory

hello，i am learning about this pedestrian trajectory prediction recently， and i try to visualize this trajectory in the raw videoes， but i failed. I saw you have done this job in your paper. so i want to know whether you can share the code? thank you

loss problem

Hello, may I ask why my loss is always 0 since the first epoch?

Ablation Result - Table 4

Hi Inhwan,

I tried to reproduce the ablation study result in your table 4, especially for the intra-only (variant 1) and inter-only (variant 2) experiments. It seems that my reproduced intra-only result (avg-0.25/0.45) is better than my reproduced inter-only result (avg-0.31/0.53), which violates your result in table 4. The values are close to what you reported in the table but they do not correspond to the correct settings. It seems that the intra-group interactions has a stronger influence on the final prediction result.

I am not sure whether it is my fault or you made the mistake in the table. In your code, the inter-group flag is before intra-group flag, but in your ablation table intra-group column is before the inter-group column. Please let me know if I missed something or some possible mistakes I've made in reproducing table 4 results. If anyone have reproduced the results in table 4, please share your results.

Group Visualization

Hello, I am very interested in your work.
I would like to know how it is done in the group visualization piece and what is the name of the graph, I would like to try to plot it but I don't know the name of the graph.
