Multiple Inputs with Embedding

[diamondspark]

I am trying to explain a CNN model. My model looks as following. Please advise what am I doing wrong. Thank you! `

with DeepExplain(session=sess) as de: 

    model = load_model(sent_model_paths)
    input_tensor = model.inputs
    embedding_tensor = model.layers[6].input
    pre_softmax =  model.layers[-2].output
    
    x_interpret = cnn.X_test
    
    embedding_out = sess.run(embedding_tensor, {input_tensor[0]: cnn.X_test})
    
    ys = [1, 0, 0]
    
    attributions = de.explain('grad*input', pre_softmax * ys, embedding_tensor, embedding_out)
`

This gives me the following error

'
InvalidArgumentError: You must feed a value for placeholder tensor 'input_17_1' with dtype int32 and shape [?,200]
	 [[{{node input_17_1}}]]
'

My model looks as following

Have you seen issue #11 ? I recently had this error in a custom network. I was working on Jupyter notebooks and clearing the Keras session prior to loading the model helped.

model_path = 'trained_models/name-of-the-model.h5'

K.clear_session()
model = load_model(model_path)

attrib_method = 'elrp'
#%% Loop begins
with DeepExplain(session = K.get_session()) as de:
    # for performance improvements: https://github.com/marcoancona/DeepExplain#performance-explainer-api
    input_tensor   = model.layers[0].input
    fModel         = Model(inputs = input_tensor, outputs = model.layers[-2].output)
    target_tensor  = fModel(input_tensor)
    explainer      = de.get_explainer(attrib_method, target_tensor, input_tensor)
    attributions = explainer.run(X, ys=pred)
