np. random. Shuffle and np Use swapaxis or transfer with caution

  # y = np.transpose(y,(1,0,2))

  # y = np.random.shuffle(y)

  # y = np.transpose(y,(1,0,2))

These three lines of code will lead to ValueError: axes don't match array Error of ,
Similarly, , If you use swapaxis–shuffle–swapaxis Similar errors will occur .
Avoid this problem .
And if you want to arrange a dimension randomly , have access to permutation+ Slicing scheme ,shuffle Just for axis 0 Random .
