but i checked 2.5.2 pydantic. still there is a types.py
https://github.com/pydantic/pydantic/blob/v2.5.2/pydantic/types.py

Is there something what i miss?

To reproduce

jsonargparse 4.23.1
pydantic 2.5.2

from jsonargparse import CLI

Expected behavior

Environment

• jsonargparse version (4.23.1):
• Python version (3.9):
• How jsonargparse was installed (e.g. pip install jsonargparse[signatures]>=4.17.0):
• OS (Linux):

@elephantoid any reason why you are using an old version of jsonargparse? If there is no reason, please update to the latest version.

The unit test were run yesterday with pydantic 2.5.2, so I doubt there is a bug. See https://app.circleci.com/pipelines/github/omni-us/jsonargparse/1544/workflows/8f18309f-7759-4194-8386-499c34583192/jobs/10870
