ValueError:检查输入时出错:预期conv2d_input具有4维 - python

嘿，编写此代码来重塑我的图像，但是当我运行代码时，它给了我这个错误值错误：检查输入时出错：预期conv2d_input具有4个维，但是数组的形状为（1，3072）。看来我的输入或输出不正确，或者我必须输入4维。

print (i)
label = lb.classes_[i]
# draw the class label + probability on the output image
text = "{}: {:.2f}%".format(label, preds[0][i] * 100)
cv2.putText(output, text, (10, 30), cv2.FONT_HERSHEY_SIMPLEX, 0.7, (0, 0, 255), 2)

# show the output image
cv2.imshow("Image", output)
cv2.waitKey(0)

参考方案

更换

image = image.flatten()
print ("image after flattening",len(image))
image = image.reshape((1, image.shape[0]))
print ("image--reshape",image.shape)

与

image = np.expand_dims(image, axis=0)
