GRIP++ on NGSIM

Hi,I read your paper, it inspired me a lot and opened up a new direction for me to think, thank you very much. But I had a hard time running experiments with this dataset of NGSIM.Is it possible that you can share your code for the NGSIM dataset or the data loader code with me? It will be very helpful. my email address is [1634959098@qq.com].
