This script will help you convert any LeRobot dataset already pushed to the hub from codebase version 1.6 to
2.0. You will be required to provide the 'tasks', which is a short but accurate description in plain English
for each of the task performed in the dataset. This will allow to easily train models with task-conditionning.

We support 3 different scenarios for these tasks (see instructions below):
    1. Single task dataset: all episodes of your dataset have the same single task.
    2. Single task episodes: the episodes of your dataset each contain a single task but they can differ from
      one episode to the next.
    3. Multi task episodes: episodes of your dataset may each contain several different tasks.


Can you can also provide a robot config .yaml file (not mandatory) to this script via the option
'--robot-config' so that it writes information about the robot (robot type, motors names) this dataset was
recorded with. For now, only Aloha/Koch type robots are supported with this option.


# 1. Single task dataset
If your dataset contains a single task, you can simply provide it directly via the CLI with the
'--single-task' option.

Examples:

```bash
python lerobot/common/datasets/v2/convert_dataset_v1_to_v2.py \
    --repo-id lerobot/aloha_sim_insertion_human_image \
    --single-task "Insert the peg into the socket." \
    --robot-config lerobot/configs/robot/aloha.yaml \
    --local-dir data
```

```bash
python lerobot/common/datasets/v2/convert_dataset_v1_to_v2.py \
    --repo-id aliberts/koch_tutorial \
    --single-task "Pick the Lego block and drop it in the box on the right." \
    --robot-config lerobot/configs/robot/koch.yaml \
    --local-dir data
```


# 2. Single task episodes
If your dataset is a multi-task dataset, you have two options to provide the tasks to this script:

- If your dataset already contains a language instruction column in its parquet file, you can simply provide
  this column's name with the '--tasks-col' arg.

    Example:

    ```bash
    python lerobot/common/datasets/v2/convert_dataset_v1_to_v2.py \
        --repo-id lerobot/stanford_kuka_multimodal_dataset \
        --tasks-col "language_instruction" \
        --local-dir data
    ```

- If your dataset doesn't contain a language instruction, you should provide the path to a .json file with the
  '--tasks-path' arg. This file should have the following structure where keys correspond to each
  episode_index in the dataset, and values are the language instruction for that episode.

    Example:

    ```json
    {
        "0": "Do something",
        "1": "Do something else",
        "2": "Do something",
        "3": "Go there",
        ...
    }
    ```

# 3. Multi task episodes
If you have multiple tasks per episodes, your dataset should contain a language instruction column in its
parquet file, and you must provide this column's name with the '--tasks-col' arg.

Example:

```bash
python lerobot/common/datasets/v2/convert_dataset_v1_to_v2.py \
    --repo-id lerobot/stanford_kuka_multimodal_dataset \
    --tasks-col "language_instruction" \
    --local-dir data
```
