In addition to using your custom predictor you can also make your custom observation ready for rendering. (This can be done in a similar way for your predictor).
All you need to do in order to render your custom observation is to populate :code:`self.env.dev_obs_dict[handle]` for every agent (all handles). (For the predictor use :code:`self.env.dev_pred_dict[handle]`).
In contrast to the previous examples we also implement the :code:`def get_many(self, handles=None)` function for this custom observation builder. The reasoning here is that we want to call the predictor only once per :code:`env.step()`. The base implementation of :code:`def get_many(self, handles=None)` will call the :code:`get(handle)` function for all handles, which mean that it normally does not need to be reimplemented, except for cases as the one below.
