如何将包含两个 numpy arrays 的 python 列表转换为 Z2EA9510C37F7F89E1CBZZ 数组？

Question

Suppose, X is [array([2, 3, 4]), array([4, 5, 6])]

I want X to be

array([[ 2,  3,  4],
       [4, 5, 6]])

Answer 1

Just use np.array(...) and create an array:

>>> X = [array([2, 3, 4]), array([4, 5, 6])]
>>> np.array(X)
array([[2, 3, 4],
       [4, 5, 6]])
>>> 

Answer 2

Try this:

array = numpy.stack(X, axis=0)

You could also do:

array = numpy.vstack(X)
