This "backwards" meme doesn't make any sense. Python 2 and Python 3 are different languages that happen to share the same name, a lot of syntax, and near-source compatibility, but they've been developed concurrently for ten years now. It's kind of like C and C++. If the current Python 2 team (which is part of the Python Software Foundation) abandons it, probably somebody else will take over maintenance, because it seems unlikely that it will fall out of use.

If the Python Software Foundation drops the ball, someone else will pick it up.

I am really excited about this library. Tensors are the future; matrices are going to look so old in a few years. In fairness, Theano already knew that. I cannot wait to dig into this and am very relieved that Google's best are still using Python for this endeavour...but...using Python 2.7.

I have just recently been persuaded by the community that 3.5 is cost free, and here I have this enormous counterexample. For the science guys, clearly, the message is not getting through, and I'm not surprised: 3.x offers them nothing. Hence they're blissfully continuing with 2.7.

So I guess I'll have to run two Pythons on my system. Not the ideal situation.

Now if Python 3.(x > 5) would give us native GPU, which might require putting (a GPU-enabled) Numpy into the standard library...as opposed to, say, spending 2 years re-inventing Tornado....

There's a note on the site about being able to move computation to a process on a different machine, but it does mention copying the model. If I understand correctly, I think models tend to be quite small, though.

Does it actually make sense to train a model simultaneously on different machines? I can understand running the same model on lots of machines, of course.

This is really significant. At this moment in history, the growth of computer power has made a bunch of important signal-processing and statistical tasks just feasible, so we are seeing things like self-driving cars, superhuman image recognition, and so on. But it's been very difficult to take advantage of the available computational power, because it's in the form of GPUs and clusters. TensorFlow is a library design…
