TypeError: Fetch argument None has invalid type <class 'NoneType'>

[GDissard]

Hi, first thing: your project is very interesting
Second: I got an error at the execution at line 164 : result = sess.run([cost,merged,accuracy],feed_dict = {input_data: X_batch, targets: y_batch, keep_prob:1})

Do you know where this could come from ?

Thank you in advance

Could you show the error?

Here is the error:

It has got to do with the updates in Tensorboard. Will fix it over Christmas break:)

[RobRomijnders]

How does it work for you now?

Rob - First, great code/project. Second, I get the same error/same location with the new code. Running Tensorflow r0.12.

Any thoughts?

Has to do with the section sess.run([model.cost, model.merged, model.accuracy], ....
model.merged is none as no summaries are added... remove it and the corresponding summ parameter and it should run

Thx
