cannot serialize '_io.TextIOWrapper' object

[jdebec]

Hi! I m trying to run the code, but when i try execute:

model = seq2seq_wrapper.Seq2Seq(xseq_len=xseq_len, 
                                yseq_len=yseq_len, 
                                xvocab_size=xvocab_size, 
                                yvocab_size=yvocab_size, 
                                ckpt_path='ckpt/twitter/', 
                                emb_dim=emb_dim, 
                                num_layers=3)

I got the following error:

TypeError                                 Traceback (most recent call last)

     78         # build comput graph

     80         sys.stdout.write('</log>')

    172                     reductor = getattr(x, "__reduce_ex__", None)
    173                     if reductor:
--> 174                         rv = reductor(4)
    175                     else:
    176                         reductor = getattr(x, "__reduce__", None)

TypeError: cannot serialize '_io.TextIOWrapper' object

I have no idea of what can be the error. My guess is that there is a problem with number of layers (tried different values like 1 without success) ... As i am really a newbie on tensorflow or seq2seq, i am unable to correct anything

Any help or suggestion would be most welcome! Thanks in advance!

I am also getting the same error

[AdaZhao1211]

same here

[camdirigo]

I am getting this error as well. The previous errors I was receiving were AttributeError: 'NoneType' object has no attribute 'update' and ValueError: ctypes objects containing points cannot be pickled. I resolved these errors by inserting the following within the __init__ function of the Seq2Seq class:

self.num_layers = num_layers self.xvocab_size = xvocab_size self.yvocab_size = yvocab_size self.emb_dim = emb_dim

The error is occurring at line 33 in the 03-Twitter-chatbot.py script (num_layers=3) and leads to line 61 of seq2seq_wrapper.py:

self.decode_outputs, self.decode_states = tf.contrib.legacy_seq2seq.embedding_rnn_seq2seq(self.enc_ip,self.dec_ip, stacked_lstm, xvocab_size, yvocab_size, emb_dim)

@camdirigo the same error AttributeError: 'NoneType' object has no attribute 'update'. Do you know how to fix it?

[DataTerminatorX]

same here. changed many tensorflow versions( from 0.12.0 to 1.3.0) still unsolved

[Pankajchandan]

@suriyadeepan I am getting the same error, any pointers?

[NoushNabi]

I am getting the same error as well. Also these ones: 'NoneType' object has no attribute 'update' and ValueError: ctypes objects containing points cannot be pickled.
