ImportError: cannot import name '_obtain_input_shape' from keras

In Keras,

I'm trying to import _obtain_input_shape as follows: 

from keras.applications.imagenet_utils import _obtain_input_shape

However, I get the following error:

ImportError: cannot import name '_obtain_input_shape'

The reason I'm trying to import _obtain_input_shape is so that I can determine the input shape(so as to load VGG-Face as follows :

I'm using it to determine the correct input shape of the input tensor as follow: 

input_shape = _obtain_input_shape(input_shape,
                                  default_size=224,
                                  min_size=48,
                                  data_format=K.image_data_format(),
                                  require_flatten=include_top)`

Please assist? Thanks in advance.

Solution

  • You don't have to downgrade Keras 2.2.2.

    In Keras 2.2.2 there is no _obtain_input_shape method in the keras.applications.imagenet_utils module. You can find it under keras-applications with the modul name keras_applications (underscore).

    So you don't have to downgrade your Keras to 2.2.0 just change:

    from keras.applications.imagenet_utils import _obtain_input_shape

    to

    from keras_applications.imagenet_utils import _obtain_input_shape
