Typed memoryviews allow efficient access to memory buffers, such as those underlying NumPy arrays, without incurring any Python overhead. 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 array ...

08.03.2021 · getbuffer has never been supported on python 3, because there is no such thing as a buffer object in Python 3. It was removed from numpy entirely in #15239, but only because we stopped supporting Python 2 at all, so that if was never run. Are you looking for one of bytes, bytearray, or memoryview? (all part of Python itself)

23.11.2016 · Cached attributes are created and cached when they are used. So users can either explicitly access the attributes that they want to be in cache and be pickled. In the generic unit tests (for non-tsa models) I added a call to summary() before pickling, because that creates most of the cached attributes.

h function, if you map it into a numpy tensor you should use transpose. Now it gives this error 'Tensor' object has no attribute 'deatch'.

07.06.2018 · Some objects may support the array-protocol and allow conversion to arrays this way. A simple way to find out if the object can be converted to a numpy array using array () is simply to try it interactively and see if it works! (The Python Way).

Typed Memoryviews ¶. Typed Memoryviews. ¶. Typed memoryviews allow efficient access to memory buffers, such as those underlying NumPy arrays, without incurring any Python overhead. 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.

The root issue is confusion of Python lists and NumPy arrays, which are different data types. NumPy methods that are invoked as np.foo(array) usually won't complain if you give them a Python list, they will convert it to an NumPy array silently. But if you try to invoke a method contained in the object, like array.foo() then of course it has to have the appropriate type already.
