您好，如果我有的是灰度图，是否只需要修改input_shape里的通道值为1就行了吗，预训练的权重还能使用吗

加载的vgg模型来预测的时候都不准确，不知道是怎么回事 example：predict('zebra.jpg') result:n12144580 corn predict('pig.jpg') result:n02325366 wood rabbit, cottontail, cottontail rabbit

关于dive_into_keras_vgg16的预测脚本问题

1

你好，目录下的ex.py文件可以跑过，但是后面预测的那部分源码在哪里，感觉看的不是很懂。能否放上完整的脚本供参考，非常感谢。 ## 现在我们开始来预测了 ## 首先写一个方法来加载并处理图片 ```python def load_image(imageurl): im = cv2.resize(cv2.imread(imageurl),(224,224)).astype(np.float32) im[:,:,0] -= 103.939 im[:,:,1] -= 116.779 im[:,:,2] -= 123.68 im = im.transpose((2,0,1)) im = np.expand_dims(im,axis=0) return im ``` ##...

vgg16_weights.h5加载权值出错

1

我用的是windows7+keras+tensorflow,但是无法使用您的vgg16_weight.h5，请问您使用的是Th后端训练的vgg16吗？一下子就掉坑里，贼爽

代码疑问

``` def load_image(imageurl): im = cv2.resize(cv2.imread(imageurl),(224,224)).astype(np.float32) im[:,:,0] -= 103.939 im[:,:,1] -= 116.779 im[:,:,2] -= 123.68 im = im.transpose((2,0,1)) im = np.expand_dims(im,axis=0) return I'm ``` 请问这个为什么三个通道要减去这个值？ 后面的转置是什么目的？不太懂，希望大神解答下谢谢！

Is this based on tensorflow? I didnot find the py file in cloning files.
