ak.forms.NumpyForm¶
The form of a ak.layout.NumpyArray, which has ak.types.PrimitiveType, possibly wrapped in one or more layers of ak.types.RegularType.
In addition to the properties and methods described in ak.forms.Form, this has the following.
ak.forms.NumpyForm.__init__¶
- ak.forms.NumpyForm.__init__(inner_shape, itemsize, format, has_identities=False, parameters=None)¶
The inner_shape is the shape[1:] of the corresponding ak.layout.NumpyArray (default []).
The format is the dtype string returned by pybind11, which is platform-dependent. A platform-independent
interpretation of this is primitive. When reading from JSON, either the primitive or the format
needs to be specified.
The itemsize is redundant, but included for safety because of the platform-dependence of format.
