cannot reshape array of size 390 into shape (195,2,2)

Question

trainX为

[[0.29405034 0.17162472]
 [0.17162472 0.34553778]
 [0.34553778 0.21624714]
 [0.21624714 0.22196797]
 [0.22196797 0.01372996]
...........]
print(len(trainX))
195

这个错误该如何解决

trainX=np.reshape(trainX,(trainX.shape[0],2,trainX.shape[1]))
cannot reshape array of size 390 into shape (195,2,2)

Answer 1

数组长度390,你将其重塑Wie195,2,2的三围数组,原数组长度390不够,需要19522个数组才行,你要的效果将其重塑为195,2,1也是一样的,和你现在的重塑为195,2,2的是一样的效果,因为你现在390的数组本来就是一个390,2的数组
