TypeError: unsupported operand type(s) for /=: 'Tensor' and 'Tensor'

I get this error message when I try to run train.py:

Traceback (most recent call last): File "train.py", line 15, in <module> tf.app.run() File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/platform/default/_app.py", line 11, in run sys.exit(main(sys.argv)) File "train.py", line 12, in main train() File "/home/urja/tf_seq2seq_chatbot/tf_seq2seq_chatbot/lib/train.py", line 28, in train model = create_model(sess, forward_only=False) File "/home/urja/tf_seq2seq_chatbot/tf_seq2seq_chatbot/lib/seq2seq_model_utils.py", line 27, in create_model forward_only=forward_only) File "/home/urja/tf_seq2seq_chatbot/tf_seq2seq_chatbot/lib/seq2seq_model.py", line 149, in __init__ softmax_loss_function=softmax_loss_function) File "build/bdist.linux-x86_64/egg/rnn_enhancement/seq2seq_enhanced.py", line 651, in model_with_buckets File "build/bdist.linux-x86_64/egg/rnn_enhancement/seq2seq_enhanced.py", line 457, in sequence_loss File "build/bdist.linux-x86_64/egg/rnn_enhancement/seq2seq_enhanced.py", line 424, in sequence_loss_by_example TypeError: unsupported operand type(s) for /=: 'Tensor' and 'Tensor'

I have the same problem,someone can help me ???

@urjan Do you solve this problem?

[urjan]

Hi,
Upgrading the tensor flow version from 5 to 6 solved it.

@urjan thanks very much ！

[urjan]

So, do you have your training script running?

@urjan no！ I find new problem！
如下：
Created model with fresh parameters.
