WebCython 0.16 introduced typed memoryviews as a successor to the NumPy integration described here. They are easier to use than the buffer syntax below, have less overhead, and can be passed around without requiring the GIL. They should be preferred to the syntax presented in this page. See Cython for NumPy users. http://docs.cython.org/en/latest/src/userguide/numpy_tutorial.html WebPreviously, Cython always defaulted to the Python bool type, which led to hard-to-debug issues when users unsuspectingly used bool in wrapping C++ code. We decided to make the choice explicit — you can import whichever you’d like: • For the Python type, do from cpython cimport bool. • For the C++ type, do from libcpp cimport bool. great lakes in order of size in area

Memoryviews are similar to the current NumPy array buffer support ( np.ndarray [np.float64_t, ndim=2] ), but they have more features and cleaner syntax. Memoryviews are more general than the old NumPy …
