MXNet Notebooks

This repo contains various notebooks ranging from basic usages of MXNet to state-of-the-art deep learning applications.

How to use

Python

The python notebooks are written in Jupyter.

• View We can view the notebooks on either github or nbviewer. But note that the former may be failed to render a page, while the latter has delays to view the recent changes.

• Run We can run and modify these notebooks if both mxnet and jupyter are installed. Here is an example script to install all these packages on Ubuntu.

  If you have a AWS account, here is an easier way to run the notebooks:

  1. Launch a g2.2xlarge or p2.2xlarge instance by using AMI ami-fe217de9 on N. Virginia (us-east-1). This AMI is built by using this script. Remember to open the TCP port 8888 in the security group.

  2. Once launch is succeed, setup the following variable with proper value

    export HOSTNAME=ec2-107-22-159-132.compute-1.amazonaws.com
    export PERM=~/Downloads/my.pem

  3. Now we should be able to ssh to the machine by

       chmod 400 $PERM
       ssh -i $PERM -L 8888:localhost:8888 ubuntu@HOSTNAME

     Here we forward the EC2 machine's 8888 port into localhost.

  4. Clone this repo on the EC2 machine and run jupyter

       git clone https://github.com/dmlc/mxnet-notebooks
       jupyter notebook

     We can optional run ~/update_mxnet.sh to update MXNet to the newest version.

  5. Now we are able to view and edit the notebooks on the browser using the URL: http://localhost:8888/tree/mxnet-notebooks/python/outline.ipynb

How to develop

Some general guidelines

• A notebook covers a single concept or application
• Try to be as basic as possible. Put advanced usages at the end, and allow reader to skip it.
• Keep the cell outputs on the notebooks so that readers can see the results without running
