 Imitating human demonstrations is a promising approach to endow robots with various manipulation capabilities.

 ## Downloading Released Datasets
 
 Released datasets can be downloaded easily by using the `download_datasets.py` script. **This is the preferred method for downloading the datasets**, because the script will also set up a directory structure for the datasets that works out of the box with examples for reproducing some benchmark results with the repository. A few examples of using this script are provided below.

 - When creating new networks (e.g. subclasses of `Module` in `models/base_nets.py`), always sub-modules into a property called `self.nets`, and if there is more than one sub-module, make it a module collection (such as a `torch.nn.ModuleDict`). This is to ensure that the pattern `model.to(device)` works as expected with multiple levels of nested torch modules. As an example of nesting, see the `_create_networks` function in the `VAE` class (`models/vae_nets.py`) and the `MIMO_MLP` class (`models/obs_nets.py`).

For this reason, in functions that expect optional dictionaries and lists (for example, the `visual_core_kwargs` argument in the  `obs_encoder_factory` function, or the `layer_dims` argument in the `MLP` class constructor), we use a default argument of `visual_core_kwargs=None` or an empty tuple (since tuples are immutable) `layer_dims=()`.
