Import pandera.pandas to define schemas for pandas objects
🚨 Breaking Change
pandera==0.24.0 has dropped the dependency on pandas and numpy and has introduced a pandas extra. This will break any users who relied on pandas as a the transitive dependency of pandera to install pandas. To remediate this, do the following:
Install pandas explicitly or use the pandas extra
pip install pandas pandera
# or
pip install 'pandera[pandas]'Change your import to pandera.pandas
All pandas-specific symbols that were exposed by the top-level pandera module are now defined in the pandera.pandas module.
# old import
import pandera as pa
# new import
import pandera.pandas as paWhat's Changed
