how to rerender video just like Project Page showing

[LangR7]

Thanks a lot for sharing the code! I want to know how to use your code to realize dynamic video training and rendering just like the video below.
Now I can only render the free view video with the object still, just like the first video on your project page.

When I try to execute python train.py --base_folder $EXPERIMENT_PATH --gin_bindings="data_dir='$DATASET_PATH'" --gin_configs configs/hypernerf_interp_ds_2d.gin

And in sdf_2d.ipynb, it seems that the definition of the hyper_encoder module is missing.

thanks for your helping!
