WebApr 10, 2024 · I am looking for validation that overwriting a numpy array with numpy.zeros overwrites the array at the location (s) in memory where the original array's elements are stored. Web有没有办法让Numpy C-extension返回一个可变长度的Numpy数组呢? 您可能会发现,使用Numpy C-API在Cython中创建Numpy扩展更容易,因为它允许您混合python和C对象,从而简化了过程。在这种情况下,创建可变长度数组没有什么困难,只需指定具有任意形状的数组 …

No conversion to a Python 'type' is needed. Its elements may be Python/C types (dtype), but the array as a whole is an object. np.zeros((len(ArgArray), dtype = np.int32) works in Python just as well as in Cython. In my limited testing both of your cdefs work. Maybe it's a matter of cython version? inches to cup conversions
