Hey team! I'm running into the below error while trying to import,

from hamilton.function_modifiers import parameterize, source

File "/home/sahil/repos/TNP_Atlas/.venv/lib/python3.11/site-packages/hamilton/data_quality/default_validators.py", line 520, in _append_pydantic_to_default_validators
    from hamilton.data_quality import pydantic_validators
  File "/home/sahil/repos/TNP_Atlas/.venv/lib/python3.11/site-packages/hamilton/data_quality/pydantic_validators.py", line 3, in <module>
    from pydantic import BaseModel, TypeAdapter, ValidationError
ImportError: cannot import name 'TypeAdapter' from 'pydantic' (/home/sahil/repos/TNP_Atlas/.venv/lib/python3.11/site-packages/pydantic/__init__.cpython-311-x86_64-linux-gnu.so)

Pydantic version: 1.10.18 (incompatible version?) Any suggestions are welcome. Thanks!

Hey! So we recently released a pydantic extension that uses TypeAdapter, a pydantic 2.0 feature

I also hit this...currently need to fix either here or the place where I need < 2, so if a fix is easy then a good idea!

should be a quick fix, we'll get this done today! Sorry for the inconvenience

@Elijah Ben Izzy -- i see, sadly not. I need to stick with pydantic < 2, lot of inter dependencies.

Yeah fixing is reasonable

or a version that doesn't use the TypeAdapter? I'm on 1.77.0

In the meanwhile for a workaround downgrade one version — we’ll have a patch fix out shortly! Sorry for the confusion.

for those following here’s a summary: • we pushed new pydantic validator — it assumed a pydantic 2.0 feature • if you have pydantic in your environment, we tried to load the new pydantic validator ◦ if you had pydantic <2.0 the import broke and errored out If you’re blocked right now, the fix is to use

sf-hamilton==1.76.0

or upgrade to pydantic 2.0+. Otherwise if you can wait a few hours we’ll have

1.77.1

out that will address this issue.

Hey folks! Released

sf-hamilton==1.77.1
