The vectorize() function is used to generalize function class.Define a vectorized function which takes a nested sequence of objects or numpy arrays as inputs and returns an single or tuple of numpy array as output. The vectorized function evaluates pyfunc over successive tuples of the input arr...
问如何使用numpy.vectorize传递参数EN若要指定要“外部”传递的参数(从源数组中排除在外)，请将排除参数...
我设法让装饰器也可以通过如下所示的子类化numpy.vectorize来处理实例方法：前言： 主线程中怎么确定某线程...
vector_square = np.vectorize(square, docstring="This function vectorizes the square operation."). print(vector_square.__doc__). 这样,当我们查看 `vector_square` 函数的文档字符串时,就能看到我们自定义的说明信息。 三、与其他函数对比。 你可能会问,Python 里不是有列表推导式、map 函数等也能实现类...

大多数内置的NumPy函数都已经向量化了,根本不需要np.vectorize修饰符。通常,numpy.vectorize修饰符将产生非常慢的结果(与NumPy相比)!作为documentation mentions in the Notes section:Thevectorizefunction is provided primarily for convenience, not for p python cv2转灰度图并存储 ...
