If you are using a custom dataset, please add your **dataset description** to `dataset_info.json` according to the following format. We also provide several examples in the next section.

```json
"dataset_name": {
  "hf_hub_url": "the name of the dataset repository on the Hugging Face hub. (if specified, ignore script_url and file_name)",
  "ms_hub_url": "the name of the dataset repository on the ModelScope hub. (if specified, ignore script_url and file_name)",
  "script_url": "the name of the directory containing a dataset loading script. (if specified, ignore file_name)",
  "file_name": "the name of the dataset file in this directory. (required if above are not specified)",
  "file_sha1": "the SHA-1 hash value of the dataset file. (optional, does not affect training)",
  "subset": "the name of the subset. (optional, default: None)",
  "folder": "the name of the folder of the dataset repository on the Hugging Face hub. (optional, default: None)",
  "ranking": "whether the dataset is a preference dataset or not. (default: false)",
  "formatting": "the format of the dataset. (optional, default: alpaca, can be chosen from {alpaca, sharegpt})",
  "columns (optional)": {
    "prompt": "the column name in the dataset containing the prompts. (default: instruction)",
    "query": "the column name in the dataset containing the queries. (default: input)",
    "response": "the column name in the dataset containing the responses. (default: output)",
    "history": "the column name in the dataset containing the histories. (default: None)",
    "messages": "the column name in the dataset containing the messages. (default: conversations)",
    "system": "the column name in the dataset containing the system prompts. (default: None)",
    "tools": "the column name in the dataset containing the tool description. (default: None)",
    "images": "the column name in the dataset containing the image inputs. (default: None)",
    "chosen": "the column name in the dataset containing the chosen answers. (default: None)",
    "rejected": "the column name in the dataset containing the rejected answers. (default: None)",
    "kto_tag": "the column name in the dataset containing the kto tags. (default: None)"
  },
  "tags (optional, used for the sharegpt format)": {
    "role_tag": "the key in the message represents the identity. (default: from)",
    "content_tag": "the key in the message represents the content. (default: value)",
    "user_tag": "the value of the role_tag represents the user. (default: human)",
    "assistant_tag": "the value of the role_tag represents the assistant. (default: gpt)",
    "observation_tag": "the value of the role_tag represents the tool results. (default: observation)",
    "function_tag": "the value of the role_tag represents the function call. (default: function_call)",
    "system_tag": "the value of the role_tag represents the system prompt. (default: system, can override system column)"
  }
}
```

After that, you can load the custom dataset by specifying `--dataset dataset_name`.

----

Currently we support dataset in **alpaca** or **sharegpt** format, the dataset in alpaca format should follow the below format:

```json
[
  {
    "instruction": "human instruction (required)",
    "input": "human input (optional)",
    "output": "model response (required)",
    "system": "system prompt (optional)",
    "history": [
      ["human instruction in the first round (optional)", "model response in the first round (optional)"],
      ["human instruction in the second round (optional)", "model response in the second round (optional)"]
    ]
  }
]
```

Regarding the above dataset, the description in `dataset_info.json` should be:

```json
"dataset_name": {
  "file_name": "data.json",
  "columns": {
    "prompt": "instruction",
    "query": "input",
    "response": "output",
    "system": "system",
    "history": "history"
  }
}
```

The `query` column will be concatenated with the `prompt` column and used as the human prompt, then the human prompt would be `prompt\nquery`. The `response` column represents the model response.

The `system` column will be used as the system prompt. The `history` column is a list consisting string tuples representing prompt-response pairs in the history. Note that the responses in the history **will also be used for training** in supervised fine-tuning.

For the **pre-training datasets**, only the `prompt` column will be used for training, for example:

```json
[
  {"text": "document"},
  {"text": "document"}
]
```

Regarding the above dataset, the description in `dataset_info.json` should be:

```json
"dataset_name": {
  "file_name": "data.json",
  "columns": {
    "prompt": "text"
  }
}
```

For the **preference datasets**, the `response` column should be a string list whose length is 2, with the preferred answers appearing first, for example:

```json
[
  {
    "instruction": "human instruction",
    "input": "human input",
    "chosen": "chosen answer",
    "rejected": "rejected answer"
  }
]
```

Regarding the above dataset, the description in `dataset_info.json` should be:

```json
"dataset_name": {
  "file_name": "data.json",
  "ranking": true,
  "columns": {
    "prompt": "instruction",
    "query": "input",
    "chosen": "chosen",
    "rejected": "rejected"
  }
}
```

----

The dataset in **sharegpt** format should follow the below format:

```json
[
  {
    "conversations": [
      {
        "from": "human",
        "value": "human instruction"
      },
      {
        "from": "gpt",
        "value": "model response"
      }
    ],
    "system": "system prompt (optional)",
    "tools": "tool description (optional)"
  }
]
```

Regarding the above dataset, the description in `dataset_info.json` should be:

```json
"dataset_name": {
  "file_name": "data.json",
  "formatting": "sharegpt",
  "columns": {
    "messages": "conversations",
    "system": "system",
    "tools": "tools"
  },
  "tags": {
    "role_tag": "from",
    "content_tag": "value",
    "user_tag": "human",
    "assistant_tag": "gpt"
  }
}
```

where the `messages` column should be a list following the `u/a/u/a/u/a` order.

We also supports the dataset in the **openai** format:

```json
[
  {
    "messages": [
      {
        "role": "system",
        "content": "system prompt (optional)"
      },
      {
        "role": "user",
        "content": "human instruction"
      },
      {
        "role": "assistant",
        "content": "model response"
      }
    ]
  }
]
```

Regarding the above dataset, the description in `dataset_info.json` should be:

```json
"dataset_name": {
  "file_name": "data.json",
  "formatting": "sharegpt",
  "columns": {
    "messages": "messages"
  },
  "tags": {
    "role_tag": "role",
    "content_tag": "content",
    "user_tag": "user",
    "assistant_tag": "assistant",
    "system_tag": "system"
  }
}
```

Pre-training datasets and preference datasets are **incompatible** with the sharegpt format yet.
