support shape as parameter

[eudoxos]

This comment in the original thread was restricting shape of the array. Please consider adding shape to pydantic-numpy (I don't have the fluency with generics to do it myself).

Yes, shape validation would be very helpful for me as well. Here's the syntax I would like:

shape is 2 by 3: shape=(2, 3) constrain to any number of rows and 2 columns: shape=(None, 2) constrain to any number of rows and 2 or 3 columns shape=((None, 2), (None, 3)) 2 or 3-dimensional: shape=((None, None), (None, None, None))

@bendichter thanks for your suggestions. Maybe we can work around the missing shape parameter using typing.Annotated. See here https://stackoverflow.com/a/72585748/242594

Thanks for the pointer!

I can implement this in April for native pydantic-numpy support

[bendichter]

That would be great!

This is now supported on pydantic-numpy ^3.0: https://github.com/caniko/pydantic-numpy
