Tensorpack is a neural network training interface based on graph-mode TensorFlow.
It's Yet Another TF high-level API, with the following highlights:
- Focus on training speed.
-
Speed comes for free with Tensorpack -- it uses TensorFlow in the efficient way with no extra overhead. On common CNNs, it runs training 1.2~5x faster than the equivalent Keras code. Your training can probably gets faster if written with Tensorpack.
-
Scalable data-parallel multi-GPU / distributed training strategy is off-the-shelf to use. See tensorpack/benchmarks for more benchmarks.
- Squeeze the best data loading performance of Python with
tensorpack.dataflow.
- Symbolic programming (e.g.
tf.data) does not offer the data processing flexibility needed in research. Tensorpack squeezes the most performance out of pure Python with various autoparallelization strategies.
- Focus on reproducible and flexible research:
- Built and used by researchers, we provide high-quality reproducible implementation of papers.
- It's not a model wrapper.
- There are too many symbolic function wrappers already. Tensorpack includes only a few common layers. You can use any TF symbolic functions inside Tensorpack, including tf.layers/Keras/slim/tflearn/tensorlayer/....
See tutorials and documentations to know more about these features.
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 papers, Tensorpack examples faithfully reproduce papers, demonstrating its flexibility for actual research.

Dependencies:
- Python 3.3+.
- Python bindings for OpenCV. (Optional, but required by a lot of features)
- TensorFlow ≥ 1.5
- TF is not not required if you only want to use
tensorpack.dataflowalone as a data processing library - When using TF2, tensorpack uses its TF1 compatibility mode. Note that a few examples in the repo are not yet migrated to support TF2.
- TF is not not required if you only want to use
pip install --upgrade git+https://github.com/tensorpack/tensorpack.git
# or add `--user` to install to user's local directories
Please note that tensorpack is not yet stable. If you use tensorpack in your code, remember to mark the exact version of tensorpack you use as your dependencies.
