porting to mxnet problem

[pribadihcr]

Hi @aiff22,

I am trying to port your code to MxNet. But there is an issue about loss function definition.
For example I can not find the corresponding ops like tf.image.rgb_to_grayscale in MxNet.

Maybe you can guide me. Thanks

Hi @pribadihcr,

While we don't have experience of using MxNet, it looks like some Tensorflow functions are not implemented there. You can solve this problem by implementing them yourself, which in case of rgb_to_grayscale is as follows (python code):

def rgb_to_grayscale(rgb):
     return np.dot(rgb[...,:3], [0.299, 0.587, 0.114])
