Updated commands for latest Tensorflow version #2

Hey Siraj,

first of all I want to say I love your videos and your code! It's really helpful for getting into Machine Learning and Deep Learning in particular.

I updated some of the Tensorflow commands in that code (some warning will be issued when executing your current code with latest the Tensorflow version)

Cheers, Sebastian

Thank you for this update. Now it's wokring with TF0.12.1 But I still have an issue with the eval-function.

Traceback (most recent call last): File "main.py", line 84, in <module> print "Accuracy:", accuracy.eval({x: mnist.test.images, y: mnist.test.labels}) File "/usr/lib/python2.7/site-packages/tensorflow/python/framework/ops.py", line 575, in eval return _eval_using_default_session(self, feed_dict, self.graph, session) File "/usr/lib/python2.7/site-packages/tensorflow/python/framework/ops.py", line 3619, in _eval_using_default_session raise ValueError("Cannot evaluate tensor using eval(): No default " ValueError: Cannot evaluate tensor using eval(): No default session is registered. Use with sess.as_default() or pass an explicit session to eval(session=sess)

Hi jkronen,

Are you running an interactive session?

Try passing session=sess to the eval function, e.g. print "Accuracy:", accuracy.eval(session=sess, {x: mnist.test.images, y: mnist.test.labels})

Good luck! Sebastian

Hey Sebastian,

thank you for your reply. I am not running an interactive session. I just have the code from here with your updates and run it from the terminal.

Changing the line to your suggestion, produces following output:

print "Accuracy:", accuracy.eval(session=sess,{x: mnist.test.images, y: mnist.test.labels})
SyntaxError: non-keyword arg after keyword arg](url)

I even tried accuracy.eval(sess,{x: or setting the session as default, but none of them worked

Greetings Jan

Hi Jan,

I'm sorry, I was a little careless, try this line:

print "Accuracy:", accuracy.eval(session=sess, feed_dict={x: mnist.test.images, y: mnist.test.labels})

If this throws an error, please report the whole error message.

Cheers, Sebastian

There you go, it's working now. Thank you very much!

Greeting Jan
