Hi !

I’ve this error.
I put something like that :
attn1, attn_weights_block1 = self.mha1(x, x, x, look_ahead_mask,return_attention_scores=True) # (batch_size, target_seq_len, d_model)
attn2, attn_weights_block2 = self.mha2(enc_output, enc_output, out1, padding_mask,return_attention_scores=True) # (batch_size, target_seq_len, d_model)

Do you have some tips to fix this error ?

Thanks !

It would help if you specify which function you’re working on. I’m going to assume it is the “call” method of DecoderLayer().

Your arguments for mha2(…) are not correct.

Yes it’s the call function of the block “decoder”.

Thanks for your help !

I am having below calls-

Can you please help to guide where I am going wrong.
Thank you.

I’m having the same issue. I have tried similar code to yours, but I also replaced

self.mha2(mult_attn_out1 by {mentor edit: code removed}

where Q1 = {mentor edit: code removed}

Any suggestions appreciated!
Edit: Figured it out. I needed: {mentor edit: code removed}
