get the exceptional answer in windows

[blackredscarf]

I use your notebook example to run, but get the exception answer

I only replace skimage resize to cv2.resive

windows 10
keras 2.1.3
python 3.5
tensorflow 1.4

Thank you for your report.
I got similar result on Windows. I mainly use Ubuntu, so I did not know that it doesn't work.

I notice you can load Keras model on Windows in the same way as Ubuntu.
In this method, I got an error on Keras 2.0.*, but it seems to have been fixed in the recent version.

from keras.models import load_model
model_path = '../model/keras/model/facenet_keras.h5'
model = load_model(model_path)

The results were subtly different between ubuntu and windows, but it's not such a big issue.

IndexError: tuple index out of range

@blackredscarf

I got the same error in the following environment.

• Python 3.5.4
• tensorflow 1.3.0
• keras 2.1.3

But it worked well in the following environment.

• Python 3.6.3
• tensorflow 1.3.0
• keras 2.1.3

I do not know why it does not work with python 3.5.
Please upgrade to python 3.6 and try it out.

[blackredscarf]

@nyoki-mtl
Thanks! That is worked.
But use load_model, I cannot change the input shape ?

[Hiroki Taniai]

@blackredscarf
Yes. This model is trained by 160*160*3 images, so if you want to change the input shape of the model, you should re-train the model by images with the shape.
However, you can use facenet for images with any shape because you can change the shape of the images by resize function.
