SDK init fails from pydantic AI integration

[Philipp-Userlike]

How do you use Sentry?

Sentry Saas (sentry.io)

Version

2.45.0

Steps to Reproduce

We just updated to version 2.45.0 from 2.44.0.
Since then sentry_sdk.init is crashing with the following traceback:

 File "xxxxx.py", line 66, in sentry_setup
    sentry_sdk.init(
  File "env/lib/python3.10/site-packages/sentry_sdk/_init_implementation.py", line 62, in _init
    client = sentry_sdk.Client(*args, **kwargs)
  File "env/lib/python3.10/site-packages/sentry_sdk/client.py", line 289, in __init__
    self._init_impl()
  File "env/lib/python3.10/site-packages/sentry_sdk/client.py", line 422, in _init_impl
    self.integrations = setup_integrations(
  File "env/lib/python3.10/site-packages/sentry_sdk/integrations/__init__.py", line 226, in setup_integrations
    for integration_cls in iter_default_integrations(
  File "env/lib/python3.10/site-packages/sentry_sdk/integrations/__init__.py", line 52, in iter_default_integrations
    yield getattr(import_module(module), cls)
  File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
  File "env/lib/python3.10/site-packages/sentry_sdk/integrations/pydantic_ai/__init__.py", line 10, in <module>
    from .patches import (
  File "env/lib/python3.10/site-packages/sentry_sdk/integrations/pydantic_ai/patches/__init__.py", line 4, in <module>
    from .tools import _patch_tool_execution  # noqa: F401
  File "env/lib/python3.10/site-packages/sentry_sdk/integrations/pydantic_ai/patches/tools.py", line 3, in <module>
    from pydantic_ai._tool_manager import ToolManager  # type: ignore
ModuleNotFoundError: No module named 'pydantic_ai._tool_manager'

It seems like pydantic_ai is imported even when it is not installed?
Seems to come from: #5111

Expected Result

There should be no crash

Actual Result

Crash, see traceback above

Hi @Philipp-Userlike,

Thanks for the report! Do you by any chance have a pydantic_ai.py or a folder named pydantic_ai in your environment? We already have a similar report for openai_agents here #5129.

We will release a fix early next week.

@alexander-alderman-webb yes actually I had those installed:

pydantic-ai==0.0.22
pydantic-ai-slim==0.0.22

When I uninstall them it works.

Sorry then it might be on my side. I was suprised this is installed as it is not inside the Pipenv.lock file that I used to set up my python environment

@Philipp-Userlike thanks for the quick reply, that's useful info!

The SDK should not crash in this case, so it's not an error on your side.

If you do not need pydantic-ai you will be safe after uninstalling it. The SDK started enabling the pydantic-ai integration automatically when pydantic-ai is in the environment with version 2.45.0.
