module 'keras.utils' has no attribute 'generic_utils'

Hi,

I’m trying to run multiclass segmentation (camvid).ipynb example and get an error after running the following block:

import segmentation_models as sm

Here is the error:

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

      4 # or you could switch to other framework using `sm.set_framework('tf.keras')`

Can anyone help me to solve this?
