import error for control_flow_ops

Found error when trying to run code as is. Changing
from tensorflow.python import control_flow_ops to from tensorflow.python.ops import control_flow_ops fixed issue.

Missing backpropagation method

I ran this code, but I found that this model wasn't properly trained at all. I think, in this 6th block, the code may require a proper backpropagation method (loss.backward()), doesn't it? Unless you intended it to be so. This made me quite confused for quite long.

Rename file names

Hello,

The files with updated at the end are causing issues in the imports. Could you rename the files or change the import statements?

get_minibatch not found

Chapter 3, section 'Sessions in TensorFlow', Safari version

Cannot find source of import - where is read_data module found?

---

from read_data import get_minibatch()
^
SyntaxError: invalid syntax

from read_data import get_minibatch

---

from read_data import get_minibatch

ImportError: No module named 'read_data'

Using Python 3.5 from Conda, with TensorFlow 1.0.1

What version of TensorFlow is the code written in?

Couldn't find a requirements.txt or environment.yml.

Summary function names wrong TF API r1.7

In the logistics_regression.py code,
Calls to tf.summary functions were wrong. I assume they've all been deprecated.
changes:
tf.histogram_summary => tf.summary.histogram
tf.merge_all_summaries => tf.summary.merge_all
tf.scalar_summary => tf.summary.scalar
tf.train.SummaryWriter => tf.summary.FileWriter.

Your book is awesome by the way. Loving it immensely. Can't put it down.

where are the codes of the book?

I only find codes of ch3、ch4、ch9.
Can someone tell me where are the other chapters's code?

The script of logistic_regression

I read the script of logistic regression. I think it's just a simple linear regression (Wx+b) combined with softmax and without the operation of 1/(1+exp(-(Wx+b))) cause I don't find sigmoid activation function. Do you think so or have explanation for that?
