numpy.lib.format.dtype_to_descr

lib.format.dtype_to_descr(dtype)

Get a serializable descriptor from the dtype.

The .descr attribute of a dtype object cannot be round-tripped through the dtype() constructor. Simple types, like dtype(‘float32’), have a descr which looks like a record array with one field with ‘’ as a name. The dtype() constructor interprets this as a request to give a default name. Instead, we construct descriptor that can be passed to dtype().

Parameters:

dtypedtype

The dtype of the array that will be written to disk.

Returns:

descrobject

An object that can be passed to numpy.dtype() in order to replicate the input dtype.
