Error executing tf.train.shuffle_batch

[Samborce]

Hi,

Thank you very much for sharing your code. I downloaded your package and I tried to run it in Ubuntu 16.04 tf-1.1. I have received an error when the function tf.train.shuffle_batch is executed within the function input_line. The output error is:

Caused by op u'shuffle_batch', defined at:

Suggestions?

Thanking in advance.

@Samborce this error occurs when the queue reading elements into shuffle_batch queue reaches termination. The error is most probably due to this line. The string_input_producer function maintains a local counter to infinitely run over the string input tensor which must be initialised using local_variables_initializer as specified in the documentation. The code misses this portion.
Try running the code with tf.local_variables_initializer() before this line.

Hi, thank you very much for sharing your code,
and I have faced the same issue too,
but adding a local variables initializer didn't solve it.
Could you give me some help?

Thank you!
