なんの話かと言うと
LLM で SAS のコードを Python に変換する実験をする機会があって、Google Cloud の Gemini 1.5 Pro を使えば普通に変換できたのですが・・・
- LLM に SAS のコードを Python に変換させる
- 変換後のコードを実行して結果を確認する → 実行はできるが Warning が残っている
- LLM に Warning が出ないように修正させる
という処理を対話的に実行する必要があり、「コードの実行部分を Function calling で実装して、このループ全体を自動化できない？」と思ってやってみた結果のメモです。
※ Function calling についてはこちらを参照
注意
以下の内容は、あくまで、「やってみた」です。LLM の挙動には一定の不確定性があるので、なんでもかんでも LLM だけで自動化しようとするのは、余計な苦労が増えるだけの場合も多いです。「十徳ナイフだけでフルコース料理を作る」的な一種の競技と思って楽しんでください。
実装内容
いろいろ試行錯誤はありましたが、最後にそこそこうまくいった実装例を紹介します。
使用する SAS コードの例として、こちらを使用します。
以下のコードは、Google Cloud のプロジェクト環境で、Vertex AI API を有効化した後に、Vertex AI Workbench のノートブック上で実行していきます。
はじめに変換対象の SAS のコードを取得します。
!curl -OL https://raw.githubusercontent.com/MaxineXiong/TSA_Claims_Data_Analysis/master/TSA_Claims_Data_Analysis.sas sas_code = !cat TSA_Claims_Data_Analysis.sas sas_code = '\n'.join(sas_code)
もろもろのモジュールをインポートしたら、Python を実行する関数を Function calling のツールとして加えた LLM モデルを用意します。
import sys, json, vertexai from io import StringIO from vertexai.generative_models import \ FunctionDeclaration, GenerationConfig, GenerativeModel, Part, Tool python_runtime_func = FunctionDeclaration( name='python_runtime', description='Execute python code.', parameters={ 'type': 'object', 'properties': { 'python_code': { 'type': 'string', 'description': 'Python code in plain text format.' } }, 'required': ['python_code'] } ) model = GenerativeModel( 'gemini-1.5-pro-001', generation_config=GenerationConfig(temperature=0.1), tools=[ Tool(function_declarations=[ python_runtime_func ]) ] )
Function calling が使われるかちょっと試してみましょう。
prompt = """\ Execute a python code to say "Hello". """ model.generate_content(prompt).candidates[0].content.parts[0] ==> output <== function_call { name: "python_runtime" args { fields { key: "python_code" value { string_value: "print(\"Hello\")" } } } }
オッケーですね。
実際にコードを実行する関数は次のように実装しておきます。LLM が生成したコードを実行するので、本当は、安全な Sandbox を用意するべきですが、ここでは、ノートブックのランタイムで直接実行しちゃってます。
def exec_code(python_code): # TODO: implement a safe sandbox using container environment. old_stdout, old_stderr = sys.stdout, sys.stderr try: redirected_stdout = sys.stdout = StringIO() redirected_stderr = sys.stderr = StringIO() exec(python_code) result = { 'output': redirected_stdout.getvalue(), 'warnings': redirected_stderr.getvalue() } except Exception as e: result = {'error': str(e)} finally: sys.stdout, sys.stderr = old_stdout, old_stderr return result
そして、実際に使用するプロンプトのテンプレートです。
prompt_template = '''\ You are a professional data analyst and software engineer highly skilled in SAS and Python. Work on the following tasks. [Task] Convert the SAS code into Python and execute it by applying the function calling. #### IMPORTANT: Use the function calling to execute the python code instead of just writing a code. #### IMPORTANT: Use the function calling to execute the python code instead of just writing a code. #### IMPORTANT: Use the function calling to execute the python code instead of just writing a code. #### IMPORTANT: Use the function calling to execute the python code instead of just writing a code. #### IMPORTANT: Use the function calling to execute the python code instead of just writing a code.

コード変換時の細かな条件を [Condition] に入れて、変換対象の SAS コードを [SAS code] に入れます。
生成するコードが大きくなると、そっちで精一杯になるのか、Function calling を使うのをよく忘れるので、Function calling を使うようにしつこく言い聞かせています。
そして、冒頭で説明した自動化のループを回す関数がこちらです。Function calling を使うのを忘れた場合は、使うように即すメッセージを返して、また、Function calling によるコード実行結果に Warning / Error が含まれる場合は、修正するように依頼するメッセージを返します。

それでは実行してみましょう！

😐 You should use the real function calling to execute the python code instead of just writing a code.Gemini 1.5 Pro は、SAS や Python のコードが解釈できるので、コードの実行結果まで勝手に予測して用意したようです。それらしい出力ですが、もちろん本当の実行結果ではないので、ちゃんと Function calling を使うように指示しています。すると、次は、Function calling を指定してきました。

😐 The behavior will change in pandas 3.0. This inplace method will never work because the intermediate object on which we are setting values always behaves as a copy.
😐
😐 For example, when doing 'df[col].method(value, inplace=True)', try using 'df.method({col: value}, inplace=True)' or df[col] = df[col].method(value) instead, to perform the operation inplace on the original object.今回はうまく実行できましたが、Pandas でありがちな Warning が出ています。これも修正するように指示しています。すると、さらに次のコードを返してきました。
