### モデル概要 |
|
- **Developed by:** nakagawaKZ |
|
- **License:** apache-2.0 |
|
- **Finetuned from model [optional]:** llm-jp/llm-jp-3-13b |
|
|
|
### モデルの使い方 |
|
以下に、本モデルを用いて評価用タスク(ELYZA-tasks-100-TV)の出力結果を得るためのコードを示します。 |
|
このコードを実行することで、提出用フォーマットのjsonlファイルが出力されます。 |
|
|
|
## <前提条件> |
|
- Pythonが実行できる環境 |
|
- Huggin Faceのアクセストークンが取得済み |
|
