converted code to Tensorflow 1 and changed skimage range

[martinosorb]

The code was converted using automatic conversion provided by Tensorflow.

Additionally, the most recent skimage was telling me its images needed to be between -1 and 1, the opposite of what your code and comments said. I changed that, adding a clip since some values were (very slightly) larger than 1.0. This is slightly suspicious...

Note: I also have a python 3 version, which is NOT included in this PR, but you may be interested in.

Thanks for the PR! Honestly I haven't touched this repo in a while so I'll need to re-download the data, but I'll try to test this and merge this weekend

Would also definitely be interested in your Python 3 version!

[martinosorb]

Great, however if I push the py3, it may not be compatible with py2 anymore. Is that ok?

[dyelax]

What did you change to make it work with python3? I’d love to have it be cross-compatible if possible

[martinosorb]

I used 2to3, which does it automatically, and then ran it to check it worked (I had to make one more change before it did). The 2to3 docs state it's usually not a good idea to try making code compatible with both 2 and 3, but that's up to you.
