If you are reading or parsing the data in the API, usually we expect it to be encoded in UTF-8 format, and hence we try applying decode() on the string object. How to display Latin Modern Math font correctly in Mathematica? When I execute this code in Python 3, we encounter an AttributeError. Examples >>> s = b'hello world' >>> np.frombuffer(s, dtype='S1', count=5, offset=6) array ( [b'w', b'o', b'r', b'l', b'd'], dtype='|S1') The conversion can be avoided by typing the size variable as Py_ssize_t rather than ssize_t.. Okay so we are aware of these possible So there's some reason to expect that we need to get our desired_slice_view from a memoryview, and that therefore the first step is to get a memoryview of the whole underlying array.

"As my example shows, it is useful for doing intermediate manipulations efficiently" Your example shows no such thing, you don't do any manipulation at all you just do indexing with a different offset than zero. Why would a highly advanced society still engage in extensive agriculture? The easiest fix is to drop the decode() property on the string objects and call it directly to resolve the issue as its already in the decoded format. memoryview objects allow Python code to access the internal data of an object that supports the buffer protocol without copying. @KevinB Ive changed it so you can pass an ndarray straight to the Image ctor now. What is Mathematica's equivalent to Maple's collect with distributed option?
