Ensure that the argument is a NumPy array In case of an error, nullptr is returned and the Python error is cleared.

F-style strides; default when constructing an array_t with `ExtraFlags & f_style`

This is essentially the same as calling numpy.dtype(args) in Python.

Creates a generator to extract data from the queue. Skip the data if it is `None`. # Returns A generator

Returns true for structured data types.

On PyPy, check that "__bool__" (or "__nonzero__" on Python 2.7) attr exists

Import and return a module or throws `error_already_set`.

Default implementation: do nothing

Register a function call with Python (generic non-templated code goes here)

Equivalent to ``obj is other`` in Python.

Equivalent to ``obj is None`` in Python.
