ModuleNotFoundError: No module named 'keras.engine.topology'

[jkortner]

When I try to import keras-vggface in Google Colab I get the error: No module named 'keras.engine.topology'. The same happens on my local machine.

First, I install keras-vggface:

!pip install keras_vggface
!pip install keras_applications

Then, I try to import:

from keras_vggface.vggface import VGGFace

The output is as follows:

---------------------------------------------------------------------------

Same error for me when using the latest keras version. Keras 2.4.3/tensorflow 2.5 works fine.

I solved this issue by changing the import from from keras.engine.topology import get_source_inputs to from keras.utils.layer_utils import get_source_inputs in keras_vggface/models.py.

I made a PR for this issue.

same problem solved by this, plz accept the PR

Same thing, it worked here.

example usage

image_path = r'C:\Users\pierr\Dropbox\pierre.jpg' age_gender_prediction(image_path)

hi @rcmalli, can you please merge this pr to avoid editing every install. very much appreciated. thanks

Go inside the installed library and change that line there. from keras_vggface.vggface import VGGFace To from keras.utils import get_source_inputs

ANy similar issues can be fixed like this.Even in colab

[bibinkunjumon2020]

from keras.engine.topology import get_source_inputs from keras.utils.data_utils import get_file

from keras.utils import layer_utils

to

from keras.utils import get_source_inputs from tensorflow.python.keras.utils.data_utils import get_file from tensorflow.python.keras.utils import layer_utils
