TensorFlow automatically discovers and uses GPUs and multiple cores, and I'm assuming Google is working on better supporting multiple GPUs, which currently requires hacks/tweaking to get speedups (it's easy to 'use' them)
TensorFlow is a platform "winner" and approx 100% of all innovations will quickly be ported to TensorFlow - TBD which of the others will "keep up" with innovations as they continue to come out.
other recommendations:
- by default, TensorFlow allocates 100% of GPU RAM for each process. You'll want to control this: https://stackoverflow.com/questions/34199233/how-to-prevent-tensorflow-from-allocating-the-totality-of-a-gpu-memory https://stackoverflow.com/questions/34199233/how-to-prevent-...
- Keras. yes, this. Dramatically reduces code by 2-10x, without loss of control AFAICT.
- cloud hardware. Pretty quickly, you'll want to scale and run multiple tests at once, and e.g. quickly backup & copy data, replicate system images, etc. I use Google Cloud Hosting and it's much easier (and cheaper) than AWS. Haven't tried Azure but heard good things. At least once, Google's internet bandwidth has saved hours waiting for data transfers.
- laingc 9y agoYour comments are mostly valid, but I disagree about Keras. Although it's marvellous for patching something together quickly, if you want to branch out at all then it quickly becomes an absolute mess. Far better, in my view, is to work with the newer Estimators API. It is almost as fool-proof as Keras, but instead of trying to be a framework as such, the Estimators/learn API essentially just wraps up some of the boilerplate that you need with raw tensorflow, and internally looks fairly similar to the code you might write yourself. Consequently, it preserves the composability of TF far better than Keras.
- asah 9y agoI'll try it!
- deepnotderp 9y agoKeras definitely means you lose control, but it's a tradeoff that's worth making in many cases.
- asah 9y agodumb/quick q: why not simply add classes/functions to Keras ? I read the code and it looks pretty simple...
