- applecrazy 7y agoI'm actually looking to learn PyTorch. Where's the best place to start?
- travisporter 7y agoPytorch website has a “blitz” tutorial that was fantastic.
- rm_-rf_slash 7y agoIf you have any existing ML/DL experience, picking up PyTorch is a breeze. You could get a pretty solid understanding of the framework with an MNIST handwritten digit recognition model over the course of an afternoon, so don’t sweat looking for the “right” tutorial.
- applecrazy 7y agoAwesome, I've done some ML before. I'll just dive into the docs.
- mitchellgoffpc 7y agoHighly recommend it! I love pytorch so much, it's basically numpy with automatic backprop and CUDA support. It evaluates eagerly by default, which makes debugging a lot easier since you can just print your tensors, and IMO it's much simpler to jump between high-level and low-level details in pytorch than in tensorflow+keras. Just as one example, activation functions in pytorch are applied by calling a python function on your layer, instead of passing a string argument with the function name to the layer constructor, so you write layer = F.relu(Linear()(input)) instead of layer = Dense(activation_fn='relu')(input) As a result, it's a lot more straightforward to try out custom activation functions in PyTorch.
- cdelsolar 7y agoIs it production ready for serving PyTorch models? How about if I wanted to use something like Go to serve those models? That's fairly straightforward with Keras (Python) trained TF models.

- foxtr0t 7y agoLast I checked there was basically zero serving story for pytorch. The trade off seems all to common, tensorflow optimizes for enormous production applications first while pytorch optimizes for developer ease first. If you are trying to apply one of these libraries to a production system that doesn’t get a lot of throughput you probably shouldn’t be using them (try a linear model first). If you have a high throughput application you probably want tensorflow and just deal with the shittyness.
