TypeError: __call__() takes 2 positional arguments but 4 were given

[Imorton-zd]

decoder_inputs = Input(shape=((None, num_decoder_tokens)))

decoder_layer = AttGRUCond(latent_dim,return_sequences=True)
decoder_outputs, states = decoder_layer(decoder_inputs,encoder_outputs,state)

decoder_dense = Dense(num_decoder_tokens, activation='softmax')
decoder_seqs = decoder_dense(decoder_outputs)

When using the AttGRUCond layer, the above code snippet yields a type error:

  File "D:/intern/experiments/myAtt_with_custom.py", line 183, in <module>
    decoder_outputs, sts = decoder_layer(decoder_inputs,encoder_outputs,state)

TypeError: __call__() takes 2 positional arguments but 4 were given

I would like to ask if the way using this layer is right? Thanks.

Hi @Imorton-zd ,

you'll probably need to pass the inputs to that layer as a list:

decoder_outputs, states = decoder_layer([decoder_inputs,encoder_outputs,state])

Hi @lvapeab, thanks for your suggestion. However, I got another error after modification as your post.

Traceback (most recent call last):

TypeError: add_weight() got multiple values for argument 'name'

The error is also met at the decoder_layer line. Where is the mistake?

Hi, @MarcBS , please help me solve this problem when you have some time.

Hi, @Imorton-zd , if you show us your code maybe we will be able to give you some hint about what might be failing.
