Tensorpack is a zero-overhead training interface based on TensorFlow.

See some examples to learn about the framework. Everything runs on multiple GPUs, because why not?

• Train ResNet/SE-ResNet on ImageNet
• Train Faster-RCNN / Mask-RCNN on COCO object detection
• Generative Adversarial Network(GAN) variants, including DCGAN, InfoGAN, Conditional GAN, WGAN, BEGAN, DiscoGAN, Image to Image, CycleGAN.
• DoReFa-Net: train binary / low-bitwidth CNN on ImageNet
• Fully-convolutional Network for Holistically-Nested Edge Detection(HED)
• Spatial Transformer Networks on MNIST addition
• Visualize CNN saliency maps
• Similarity learning on MNIST

• Deep Q-Network(DQN) variants on Atari games, including DQN, DoubleDQN, DuelingDQN.
• Asynchronous Advantage Actor-Critic(A3C) with demos on OpenAI Gym

• LSTM-CTC for speech recognition
• char-rnn for fun
• LSTM language model on PennTreebank

Examples are not only for demonstration of the framework -- you can train them and reproduce the results in papers.

It's Yet Another TF wrapper, but different in:

1. Focus on training speed.

   • Speed comes for free with tensorpack -- it uses TensorFlow in the correct way with no extra overhead. On various CNNs, it runs 1.5~1.7x faster than the equivalent Keras code.

   • Data-parallel multi-GPU/distributed training is off-the-shelf to use. It is as fast as Google's official benchmark.

   • See tensorpack/benchmarks for some benchmark scripts.

2. Focus on large datasets.

   • It's painful to read/preprocess data through TF. Tensorpack helps you load large datasets (e.g. ImageNet) in pure Python with autoparallelization.

3. It's not a model wrapper.

   • There are already too many symbolic function wrappers. Tensorpack includes only a few common models, but you can use any other wrappers within tensorpack, including sonnet/Keras/slim/tflearn/tensorlayer/....

See tutorials to know more about these features.

Dependencies:

• Python 2.7 or 3
• TensorFlow >= 1.2.0
• Python bindings for OpenCV (Optional, but required by a lot of features)

pip install -U git+https://github.com/ppwwyyxx/tensorpack.git
# or add `--user` to avoid system-wide installation.

If you only want to use tensorpack.dataflow alone as a data processing library, TensorFlow is also optional.
