Design Features

TensorLayer is a new deep learning library designed with simplicity, flexibility and high-performance in mind.

• Simplicity : TensorLayer has a high-level layer/model abstraction which is effortless to learn. You can learn how deep learning can benefit your AI tasks in minutes through the massive examples.
• Flexibility : TensorLayer APIs are transparent and flexible, inspired by the emerging PyTorch library. Compared to the Keras abstraction, TensorLayer makes it much easier to build and train complex AI models.
• Zero-cost Abstraction : Though simple to use, TensorLayer does not require you to make any compromise in the performance of TensorFlow (Check the following benchmark section for more details).

TensorLayer stands at a unique spot in the TensorFlow wrappers. Other wrappers like Keras and TFLearn hide many powerful features of TensorFlow and provide little support for writing custom AI models. Inspired by PyTorch, TensorLayer APIs are simple, flexible and Pythonic, making it easy to learn while being flexible enough to cope with complex AI tasks. TensorLayer has a fast-growing community. It has been used by researchers and engineers all over the world, including those from Peking University, Imperial College London, UC Berkeley, Carnegie Mellon University, Stanford University, and companies like Google, Microsoft, Alibaba, Tencent, Xiaomi, and Bloomberg.

Multilingual Documents

TensorLayer has extensive documentation for both beginners and professionals. The documentation is available in both English and Chinese.

Extensive Examples

You can find a large collection of examples that use TensorLayer in here and the following space:

Getting Start

TensorLayer 2.0 relies on TensorFlow, numpy, and others. To use GPUs, CUDA and cuDNN are required.

Install TensorFlow:

pip3 install tensorflow-gpu==2.0.0-rc1 # TensorFlow GPU (version 2.0 RC1)
pip3 install tensorflow # CPU version

Install the stable release of TensorLayer:

pip3 install tensorlayer

Install the unstable development version of TensorLayer:

pip3 install git+https://github.com/tensorlayer/tensorlayer.git

If you want to install the additional dependencies, you can also run

pip3 install --upgrade tensorlayer[all]              # all additional dependencies
pip3 install --upgrade tensorlayer[extra]            # only the `extra` dependencies
pip3 install --upgrade tensorlayer[contrib_loggers]  # only the `contrib_loggers` dependencies

If you are TensorFlow 1.X users, you can use TensorLayer 1.11.0:

# For last stable version of TensorLayer 1.X
pip3 install --upgrade tensorlayer==1.11.0
