This function is useful to be sure that an array with the correct flags is returned for passing to compiled code (perhaps through ctypes). Parameters ---------- a : array_like The object to be converted to a type-and-requirement-satisfying array. dtype : data-type The required data-type. If None preserve the current dtype. If your application requires the data to be in native byteorder, include a byteorder specification as a part of the dtype specification. requirements : str or sequence of str The requirements list can be any of the following * 'F_CONTIGUOUS' ('F') - ensure a Fortran-contiguous array * 'C_CONTIGUOUS' ('C') - ensure a C-contiguous array * 'ALIGNED' ('A') - ensure a data-type aligned array * 'WRITEABLE' ('W') - ensure a writable array * 'OWNDATA' ('O') - ensure an array that owns its own data * 'ENSUREARRAY', ('E') - ensure a base array, instead of a subclass ${ARRAY_FUNCTION_LIKE} .. versionadded:: 1.20.0 Returns ------- out : ndarray Array with specified requirements and type if given. See Also -------- asarray : Convert input to an ndarray. asanyarray : Convert to an ndarray, but pass through ndarray subclasses. ascontiguousarray : Convert input to a contiguous array. asfortranarray : Convert input to an ndarray with column-major memory order. ndarray.flags : Information about the memory layout of the array. Notes ----- The returned array will be guaranteed to have the listed requirements by making a copy if needed. Examples -------- >>> x = np.arange(6).reshape(2,3) >>> x.flags C_CONTIGUOUS : True F_CONTIGUOUS : False OWNDATA : False WRITEABLE : True ALIGNED : True WRITEBACKIFCOPY : False >>> y = np.require(x, dtype=np.float32, requirements=['A', 'O', 'W', 'F']) >>> y.flags C_CONTIGUOUS : False F_CONTIGUOUS : True OWNDATA : True WRITEABLE : True ALIGNED : True WRITEBACKIFCOPY : False N)�dtype� requirements)r c �L � h | ]!}t |� � � ��"S � )�POSSIBLE_FLAGS�upper)�.0�xs �J/opt/cloudlinux/venv/lib64/python3.11/site-packages/numpy/core/_asarray.py� <setcomp>zrequire.<locals>.<setcomp>l s% � �D�D�D�!�N�1�7�7�9�9�-�D�D�D� r FTr r r z%Cannot specify both "C" and "F" order)r �order�copy�subok)�_require_with_liker �remove� ValueErrorr �flagsr& )�ar r r r' r% �arr�props r" r r sL � �L ��!� � ��%� � � � � � *��!�5�)�)�)�)�D�D�|�D�D�D�L� �l������C� � � ������ �E���S�z�!�!��@�A�A�A� � � � ������C� � � � � � � � ������C� � � � ���e�%�u� E� E� E�C� � #� #���y��� #��8�8�E�?�?� "� "� "� #� �Jr$ )NN) �__doc__� overridesr r r � multiarrayr r �__all__r r r( r r$ r" �<module>r3 s� ��� � � � � � � � � � � � *� )� )� )� )� )� )� )� �+�� �c�� �c�c� �� �3� �� �S� � �� � ��G���f�d� f� f� f� f� �� � �f�R /�,�,�.�.�w�7�7� � � r$
