script: Subset 'res-SENS' of the initial dataset, 1/5th time steps, converted to

```
This dataset was generated with [`plaid`](https://plaid-lib.readthedocs.io/), we refer to this documentation for additional details on how to extract data from `plaid_sample` objects.
The simplest way to use this dataset is to first download it:
```python
from plaid.storage import download_from_hub
repo_id = "channel/dataset"
local_folder = "downloaded_dataset"
download_from_hub(repo_id, local_folder)
```
Then, to iterate over the dataset and instantiate samples:
```python
from plaid.storage import init_from_disk
local_folder = "downloaded_dataset"
split_name = "train"
datasetdict, converterdict = init_from_disk(local_folder)
dataset = datasetdict[split]
converter = converterdict[split]
for i in range(len(dataset)):
plaid_sample = converter.to_plaid(dataset, i)
```
It is possible to stream the data directly:
```python
from plaid.storage import init_streaming_from_hub
repo_id = "channel/dataset"
datasetdict, converterdict = init_streaming_from_hub(repo_id)
dataset = datasetdict[split]
converter = converterdict[split]
for sample_raw in dataset:
plaid_sample = converter.sample_to_plaid(sample_raw)
```
Sample features can then be retrieved as follows:
```python
from plaid.storage import load_problem_definitions_from_disk
local_folder = "downloaded_dataset"
pb_defs = load_problem_definitions_from_disk(local_folder)
# or
from plaid.storage import load_problem_definitions_from_hub
repo_id = "channel/dataset"
pb_defs = load_problem_definitions_from_hub(repo_id)
pb_def = next(iter(pb_defs.values()))
plaid_sample = ... # use a method from above to instantiate a plaid sample
for t in plaid_sample.get_all_time_values():
for path in pb_def.input_features:
feature = plaid_sample.get_feature_by_path(path=path, time=t)
...
for path in pb_def.output_features:
feature = plaid_sample.get_feature_by_path(path=path, time=t)
...
```
For those familiar with HF's `datasets` library, raw data can be retrieved without using the `plaid` library:
```python
from datasets import load_dataset
repo_id = "channel/dataset"
datasetdict = load_dataset(repo_id)
for split_name, dataset in datasetdict.items():
for raw_sample in dataset:
for feat_name in dataset.column_names:
feature = raw_sample[feat_name]
```
Notice that raw data refers to the variable features only, with a specific encoding for time variable features.
