python 转置

Nmupy 多维数组转置两种方法：

>>> data = np.array([[1,2,3],[4,5,6]])
>>> data
array([[1, 2, 3],
       [4, 5, 6]])
>>> data.transpose()
>>> np.transpose(data)

注意： Numpy 一维数组转置

>>> data = np.arange(10)
>>> data
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> data_test1= data.transpose()		# invalid
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> data_test1.shape
(10,)

# 这种方法也可以
>>> data.shape = (10,1)
>>> data_test2 = data
>>> data_test2.shape
(10, 1)
