bug:TypeError: Fetch argument

[amoliu]

hi , I got the following issues, when I running the program. Please help fix it :) thanks.
Traceback (most recent call last):

It looks like your copy of tensorflow doesn't want a list as input for the fetch argument to session.run.
What version of tensorflow are you using? To find out run
python -c "import tensorflow as tf;print(tf.__version__)"

Right now I'm not planning to support versions of tensorflow older than 0.11 since the code is mostly a learning exercise.

Try swapping
h_0 = col_0.session.run(col_0.h, feed_dict={col_0.o_n:fake1})
for
h_0 = col_0.session.run([col_0.h], feed_dict={col_0.o_n:fake1})

on line 154 since your version of TF is asking for a Tensor. If that works you'll need to do the same for all the fetch arguments.

thanks very much for quickly replying.
after upgrading the tf from 0.8 to 11.0, the issue have gone .

@yinghuochong:~/git/prog_nn$ python -c "import tensorflow as tf;print(tf.version)"
0.8.0

You're most welcome!
