Tensorpack Examples

Training examples with reproducible performance.

The word "reproduce" should always mean reproduce performance. With the magic of SGD, wrong deep learning code often appears to work, especially if you try it on toy datasets. Github is full of deep learning code that "implements" but does not "reproduce" methods, and you'll not know whether the implementation is actually correct. See Unawareness of Deep Learning Mistakes.

We refuse toy examples. Instead of showing tiny CNNs trained on MNIST/Cifar10, we provide training scripts that reproduce well-known papers.

We refuse low-quality implementations. Unlike most open source repos which only implement methods, Tensorpack examples faithfully reproduce experiments and performance in the paper, so you're confident that they are correct.

Getting Started:

These are the only toy examples in tensorpack. They are supposed to be just demos.

• An illustrative MNIST example with explanation of the framework
• Tensorpack supports any symbolic libraries. See the same MNIST example written with tf.layers, and with weights visualizations
• A tiny Cifar ConvNet and SVHN ConvNet
• If you've used Keras, check out Keras+Tensorpack examples
• A boilerplate file to start with, for your own tasks
