KeyError: 'zeropadding2d'

[hoda213]

Hello, I am trying to apply deeplift on my image dataset with densenet121 model but I get error: my code is:

import deeplift from deeplift.layers import NonlinearMxtsMode from deeplift.conversion import kerasapi_conversion as kc from tensorflow.keras.layers import ZeroPadding2D,BatchNormalization,Conv2D,Concatenate saved_model_file='model.h5'

Three different models, one each for RevealCancel, Gradient and GuidedBackprop revealcancel_model = kc.convert_model_from_saved_files( h5_file=saved_model_file, nonlinear_mxts_mode=NonlinearMxtsMode.RevealCancel) grad_model = kc.convert_model_from_saved_files( h5_file=saved_model_file, nonlinear_mxts_mode=NonlinearMxtsMode.Gradient) guided_backprop_model = kc.convert_model_from_saved_files( h5_file=saved_model_file, nonlinear_mxts_mode=NonlinearMxtsMode.GuidedBackprop)

and my error is: KeyError: 'zeropadding2d'

KeyError Traceback (most recent call last) in () 14 guided_backprop_model = kc.convert_model_from_saved_files( 15 h5_file=saved_model_file, ---> 16 nonlinear_mxts_mode=NonlinearMxtsMode.GuidedBackprop)

I would be grateful if you have any idea to solve it
