python中的数组形状

Question

这将是一个相当愚蠢的问题，尽管它很烦人。我列出了800个ndarray，每个都有7680个元素。我如何得到这个＆lt; 800,7680＆gt;格式？

Answer 1

将其传递给np.array工厂函数。举个例子：

>>> lst = [np.zeros(7680) for x in range(800)]  #just a list of 800 ndarrays ...
>>> arr = np.array(lst)   #make them into an array
>>> arr.shape   #shape looks OK to me :-)
(800, 7680)
