When I run python board.py

[agan112]

File "board.py", line 74
print "Iteration:", '%04d' % (iteration + 1), "cost=", "{:.9f}".format(avg_cost)
^
SyntaxError: invalid syntax

seems like you are using python3.. this error is due to the lack of parentheses around the print statement..
it should look something like this

print ("Iteration:", '%04d' % (iteration + 1), "cost=", "{:.9f}".format(avg_cost))

I had the same issue. This is caused by python version 3. The project needs python 2 to run. So I setup a conda virtual environment with python 2.7 and tensorFlow for python 2.7 to fix this issue. After you fix this, you will have multiple other issues such as TypeError: only integer scalar arrays can be converted to a scalar index. I will comment on another post about how I fixed it.
