执行

import numpy as np
t1 = np.arange(1,10)
t2 = np.arange(11,20)

t3 = np.concatenate((t1,t2),axis=1)

结果是

Traceback (most recent call last):

  File "<ipython-input-264-85078aa26398>", line 1, in <module>
    t3 = np.concatenate((t1,t2),axis=1)

IndexError: axis 1 out of bounds [0, 1)

为什么报告轴1超出范围？
