关于报错ValueError: Error when checking input: expected conv2d_input to have 4 dimensions

报错
ValueError: Error when checking input: expected conv2d_input to have 4 dimensions, but got array with shape (150, 150, 3)

源代码：

image = mpimg.imread("./ima/b.jpg")
image = image/255
classe = model.predict(image, batch_size=1)

原因:
输入的格式不对
解决办法：
将数据集标准化

具体解决办法：

image = mpimg.imread("./ima/b.jpg")
image = image.reshape(image.shape(1,150,150,3)/255
classe = model.predict(image, batch_size=1)
