ValueError:layer sequential的输入0与layer:：expected min\u ndim=4不兼容，found ndim=3。收到完整形状：（无、1024、3）

Question

我在图像处理机器学习中的预测代码有一个错误，这是我的代码

# load the trained model
model = load_model('./model/modelLeNet5.h5')
x=(img1/255)

# predict the input image using the loaded model
pred1 = model.predict_classes(x)

错误显示：

ValueError: Input 0 of layer sequential is incompatible with the layer: : expected min_ndim=4, found ndim=3. Full shape received: (None, 1024, 3)
