tfdot would not work with Python3

[rkuo]

I installed TensorFlow with Anaconda Python3 version. But there is not output from tfdot. I do not know whether is just Python2/3 problem or not.

• I removed op from TensorFlow's api in tfdot, which passed the compile error.
• I got off some error message by modifying some print statements in notebook.

tfdot is very nice feature, which reduce the dependence on TensorBoard. Can you update tfdot?

Just got my laptop back today and installed tensorflow. If it is not too difficult, I think it can be fixed by tomorrow.
The op issue indicates that there might be some internal API change.

The nvidia driver was causing kernel issue on my laptop and upgrading ubuntu screwed up the system. Not a big deal but need some time.

[rkuo]

Please do not feel pressured about this. I am happy you are willing to update this. I can wait.

[tjwei]

:) I am going to upgrade the system sooner or later anyway. I am actually happy to have some motivation to do it.

Upgraded to ubuntu 16.04 and latest tensorflow. Now the two major notebook (TensorFlowBasic.ipynb and MNIST.ipynb) and tfdot should work for both python 2 and python 3.

I must made mistake somewhere. I re-clone the repo. I could run TensorFlowBasic without any error message, but I did not have any output from tfdot. Any tip for me to check my installation?

You need to install graphviz binary and graphviz python module.
On ubuntu, you need both
sudo apt-get install graphviz
and
sudo pip3 install graphviz

I think I got it working. Thank you.

It printed out a lot more details than I expected (more than your demo video)
Since I used Mac, and I am new to all these, so I write down some notes here.

brew install graphviz  (I think I also did `conda install graphviz`, one of three steps is redundant!!)
pip install graphviz

check

➜  bin git:(master) pip list | grep graphviz
graphviz (0.4.10)
➜  bin git:(master) conda list | grep graphviz
graphviz                  2.38.0

try it

➜  bin git:(master) dot -h
dyld: Library not loaded: /usr/lib/libltdl.7.dylib

  Reason: image not found
[1]    23225 trace trap  dot -h
➜  bin git:(master) brew install libtool --universal
...cut ...

got error msg, then

➜  bin git:(master) brew link libtool
Warning: Already linked: /usr/local/Cellar/libtool/2.4.6

test

➜  bin git:(master) dot -V
dot - graphviz version 2.38.0 (20140413.2041)

OK, run notebook, works!!! :-) Thank you again.

Can you double check the code? Why the system prints out randim_normal, weight, .. when we just add two matrices together?

[tjwei]

Maybe it is because tensorflow did a lot of work behind scenes. I will run and check it again.
