error with NN part

[un-lock-me]

hey omid,
why when I am running your simple NN code it raises error:
return bytes_or_text.decode(encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 85: invalid start byte

It has problem with last part I mean optimization,

Actually, it is the problem with version of python. When you use python 3.x you should make some change.
I just change all the w and r into wb and rb in tf.gfile.Open and tf.gfile.FastGFile and it works.
complete code looks like:

from tensorflow.python.tools import optimize_for_inference_lib

input_graph_def = tf.GraphDef()
with tf.gfile.Open(output_frozen_graph_name, "rb") as f:
    data = f.read()
    input_graph_def.ParseFromString(data)

output_graph_def = optimize_for_inference_lib.optimize_for_inference(
        input_graph_def,
        ["I"], # an array of the input node(s)
        ["O"], # an array of output nodes
        tf.float32.as_datatype_enum)

# Save the optimized graph

f = tf.gfile.FastGFile(output_optimized_graph_name, "wb")
f.write(output_graph_def.SerializeToString())
