ValueError：连续图层15的输入0与该图层不兼容：预期ndim = 3，找到的ndim = 2。收到的完整图形：[1000、8]

Question

使用RNN的Weatherhistory.csv ValueError：连续图层15的输入0与该图层不兼容：预期ndim = 3，找到的ndim = 2。收到的完整图形：[1000、8] 什么需要进行更改？？

print(X_train.shape)
print(X_test.shape)
print(y_train.shape)
print(y_test.shape)

Output:
(60000, 8)
(20000, 8)
(60000,)
(20000,)
