I also have this problem while running the view_steering_model.py

Is there anyone else knows why?

`python view.py ./outputs/steering_model/steering_angle.json Using TensorFlow backend.

I have same problem, too.

I hope this info will help us. https://github.com/keras-team/keras/issues/8612#issuecomment-347631367
