I have a python code with Evidently library. But when i try to import like this. It causes Assertion error.

` import evidently

from evidently import ColumnMapping

from evidently.report import Report

from evidently.metric_preset import DataDriftPreset `

Hey @khangt1k25

the quick solution is to change import from from evidently.pipeline.column_mapping import ColumnMapping to from evidently import ColumnMapping

Although we'll check what's going on with the initial import

Hi @emeli-dral , I changed that but it's still error. I figure out that the error come from two lines of code.

from evidently.report import Report from evidently.metric_preset import DataDriftPreset

Hi @khangt1k25 ! Can you check your pydantic version? Looks like this assertion fails because of old pydantic, try upgrade it. We also should add constraints on it in our requirements
