Description

I see that reach datapoint has the following keys - `dict_keys(['dx_dt', 'image', 'other', 'x'])`.

In the implementation of [Physics inspired models](https://github.com/deepmind/deepmind-research/tree/master/physics_inspired_models), only `image` key has been used.

I want to use this dataset, but not as images. My questions are:

1. Is it possible to use trajectories of all the 17 datasets without images?
2. Do the keys `x, dx_dt` refer to trajectory points and derivatives?
