 * [sage-notebook](https://github.com/sharpTrick/sage-notebook) is a community Jupyter Docker Stack image with the [sagemath](https://sagemath.org) kernel on top of the minimal-notebook image.

+* [GPU-Jupyter](https://github.com/iot-salzburg/gpu-jupyter/): Leverage Jupyter Notebooks with the power of your NVIDIA GPU and perform GPU calculations using Tensorflow and Pytorch in collaborative notebooks.
+This is done by generating a Dockerfile, that consists of the **nvidia/cuda** base image, 
+the well-maintained **docker-stacks** that is integrated as submodule 
+and GPU-able libraries like **Tensorflow**, **Keras** and **PyTorch** on top of it.

 See the [contributing guide](../contributing/stacks.md) for information about how to create your own Jupyter Docker Stack.
