Any idea why this below import error?

>>> import dspy

Python 3.10.13 Installation Command : pip install dspy-ai openai version : 1.3.6

I also started getting this error as of today after updating packages in our project. We also tightened the python requirement to not include 3.11 so we are now on 3.10. Might be a 3.10 issue

[Oyveloper]

Downgraded to 3.1.10 and it worked perfectly

Python 3.10.12 - also getting this error

[okhat]

Is this a pydantic version problem?

[okhat]

Ok let's check. It seems that it works with pip, and it seems that for at least one person poetry doesn't work. Is this what people observe here?

[danpechi]

Is this a pydantic version problem?

Upgrading pydantic worked! Thanks!!

[okhat]

How did you guys install?

[okhat]

Fixed I believe. Try now:

pip install -U dspy-ai

We hadn't selected Pydantic >2.0 explicitly

[ujjawal-ti]

Thanks @okhat , Solved. Closing the issue.

I succeeded. python=3.10 and use pip install -U dspy-ai

[tom-doerr]

@Zuo-Peng Did you have issues with pip install dspy?

[Zuo-Peng]

@tom-doerr There's no problem using pip install dspy. But need to control the python version.Python version can't be too high.
