To run functional.py example locally, I need to escape """ in Python docstrings

[simonff]

Somehow, https://github.com/stanfordnlp/dspy/blob/main/examples/functional/functional.ipynb works for me on github, but when I try to run the

predictor = TypedPredictor(CodeSignature)
prediction = predictor(
    prompt=PythonCode(code=ds['test'][0]['prompt']),
    test=PythonCode(code=ds['test'][0]['test']),
    entry_point=ds['test'][0]['entry_point']
)

print(prediction)

section in a regular Python script, I keep getting JSON decoding errors.

To fix them, I had to change in dspy/functional/functional.py the return value of _unwrap_json(): return output.replace('"""', '\"\"\"')

Otherwise the """ in the generated code confuse JSON parser (you can replicate by just using json.loads() on the string below):

'{"code": "from typing import List\\n\\n\\ndef has_close_elements(numbers: List[float], threshold: float) -> bool:\\n    \\"\\"\\" Check if in given list of numbers, are any two numbers closer to each other than\\n    given threshold.\\n    >>> has_close_elements([1.0, 2.0, 3.0], 0.5)\\n    False\\n    >>> has_close_elements([1.0, 2.8, 3.0, 4.0, 5.0, 2.0], 0.3)\\n    True\\n    \\"\\"\\"\\n    for i in range(len(numbers)):\\n        for j in range(i + 1, len(numbers)):\\n            if abs(numbers[i] - numbers[j]) < threshold:\\n                return True\\n    return False"}'

Thank you @simonff ! Could be of interest to @thomasahle but it sounds like you sort of have a PR in mind @simonff ?

[simonff]

I need to get approval from work for submitting PRs, and I'm not sure I have all the right context here anyway, so I'd rather wait a bit for someone more knowledgeable to comment.

[thomasahle]

This is super interesting. I'll have a look. What language model are you using? Gpt-3.5-turbo?

[simonff]

Yes, gpt-3.5-turbo and also gemini-1.0-pro

Sorry for the typo above, the replacement string should have double backslash escapes before each quote.

I think the issue was actually that the signature was mistakenly defined to be:

class CodeSignature(Signature):
    prompt: str = InputField()
    test: PythonCode = InputField()
    entry_point: str = InputField()
    solution: PythonCode = OutputField()

Instead of

class CodeSignature(Signature):
    prompt: PythonCode = InputField()
    test: PythonCode = InputField()
    entry_point: str = InputField()
    solution: PythonCode = OutputField()

I fixed that now, and also added some robustness via parsing through ujson instead of json. Do you mind checking in my fork whether it works for you as well?

Thank you, Thomas! Can confirm the problem is gone if I use your fork.
