[已解决]numpy中empty的函数不生效

83519489

np.empty(6)
array([0., 0., 0., 0., 0., 0.])
#本应该是随机的没有具体数值，但是无论输入几次都是0
其他函数使用都是正常，就empty有问题
请大神们赐教

empty, unlike zeros, does not set the array values to zero, and may therefore be marginally faster.
On the other hand, it requires the user to manually set all the values in the array, and should be used with caution.

感谢~发完帖子才发现不能在ones和zeros后面使用，不然数组内全是0或者1
