pandera not compatible with numpy 2.0

[ostetzer]

Pandera seems to be incompatible with the neweset version of numpy 2.0: When defining a simple class based on DataFrameModel, the following error occurs duing import:

... from pandera.engines import numpy_engine, pandas_engine ... AttributeError: np.string_ was removed in the NumPy 2.0 release. Use np.bytes_ instead.. Did you mean: 'strings'?

A clear and concise description of what the bug is.

• [ x] I have checked that this issue has not already been reported.
• [x ] I have confirmed this bug exists on the latest version of pandera.

Expected behavior

Pandera should work with newest numpy version 2.0

Desktop (please complete the following information):

• OS: Windows
• Python: 3.11
• Numpy: 2.0
• Pandas: 2.2.2
• Pandera: 0.19.3

hi @ostetzer I see numpy 2 is finally in beta as a release candidate!

Can you share the schema that's raising this error?

[ostetzer]

from pandera import Field, DataFrameModel
from pandera.typing import Series


class TimeSeriesData(DataFrameModel):
    time_data: Series[float]
    sensor_data: Series[float]

As mentioned above, the error occurs already during import (import numpy_engine, pandas_engine)
