$ export PATH=/usr/local/bin:/usr/local/sbin:$PATH

# Install python development tools - python2.7, pip, python-setuptools
$ brew install python pkg-config graphviz

Step 2 Install optional components - OpenCV

If you want to use OpenCV you should install it first, then build MXNet with the USE_OPENCV=1 option in the later steps.

brew tap homebrew/science
brew install opencv

Step 3 Install CUDA and cuDNN

The following instructions are for CUDA 9.1 and cuDNN 7 for macOS 10.12+ and a CUDA-capable GPU. They summarize confirmed successful builds in #9217. Alternatively, you may follow the CUDA installation instructions for macOS.

  1. Download Xcode 8.3.3 from Apple. This is the version NVIDIA specifies in its instructions for macOS. Unzip and rename to Xcode8.3.3.app.

  2. Run sudo xcode-select -s /Applications/Xcode8.3.3.app or to wherever you have placed Xcode.

  3. Run xcode-select --install to install all command line tools, compilers, etc.

  4. Run sudo xcodebuild -license accept to accept Xcode's licensing terms.

  5. Install CUDA for macOS. Specific steps are provided in NVIDIA's CUDA installation instructions.

  6. Download and install cuDNN for macOS. You will need to create a free developer account with NVIDIA prior to getting the download link.

Step 4 Build MXNet

  1. Run git clone --recursive https://github.com/apache/incubator-mxnet.git mxnet to get the latest version.

  2. Run cd mxnet.

  3. Edit the make/osx.mk file to set the following parameters:

    USE_CUDA = 1
USE_CUDA_PATH = /usr/local/cuda
USE_CUDNN = 1
USE_OPENCV = 0   # set to 1 if you want to build with OpenCV

  4. Copy the make/osx.mk to config.mk

  5. Run make. If you previously attempted to compile you might want to do make clean_all first. You can also run make -j with the number of processors you have to compile with multithreading. There'll be plenty of warnings, but there should be no errors.

  6. Once finished, you should have a file called libmxnet.so in lib/.

  7. Do cd python.

  8. Run sudo pip install -e . Note: the . is part of the command.

The CPU version of MXNet R package can be installed in R like other packages

cran <- getOption("repos")

  1. Build the shared library from the MXNet C++ source code.
  2. Install the supported language-specific packages for MXNet.

Step 1 Build the Shared Library

On Raspbian versions Wheezy and later, you need the following dependencies:

  • Git (to pull code from GitHub)

  • libblas (for linear algebraic operations)

  • libopencv (for computer vision operations. This is optional if you want to save RAM and Disk Space)

  • A C++ compiler that supports C++ 11. The C++ compiler compiles and builds MXNet source code. Supported compilers include the following:

  • G++ (4.8 or later)

Install these dependencies using the following commands in any directory:

    sudo apt-get update
    sudo apt-get -y install git cmake build-essential g++-4.8 c++-4.8 liblapack* libblas* libopencv*

Clone the MXNet source code repository using the following git command in your home directory:

    git clone https://github.com/apache/incubator-mxnet.git --recursive
    cd incubator-mxnet

If you aren't processing images with MXNet on the Raspberry Pi, you can minimize the size of the compiled library by building MXNet without the Open Source Computer Vision (OpenCV) library with the following commands:

    export USE_OPENCV = 0
    make

Otherwise, you can build the complete MXNet library with the following command:

    make

Executing either of these commands start the build process, which can take up to a couple hours, and creates a file called libmxnet.so in the mxnet/lib directory.

If you are getting build errors in which the compiler is being killed, it is likely that the compiler is running out of memory (especially if you are on Raspberry Pi 1, 2 or Zero, which have less than 1GB of RAM), this can often be rectified by increasing the swapfile size on the Pi by editing the file /etc/dphys-swapfile and changing the line CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024, then running:

  sudo /etc/init.d/dphys-swapfile stop
  sudo /etc/init.d/dphys-swapfile start
  free -m # to verify the swapfile size has been increased

Step 2 Install MXNet Python Bindings

To install Python bindings run the following commands in the MXNet directory:

    cd python
    pip install --upgrade pip
    pip install -e .

Note that the -e flag is optional. It is equivalent to --editable and means that if you edit the source files, these changes will be reflected in the package installed.

You are now ready to run MXNet on your Raspberry Pi device. You can get started by following the tutorial on Real-time Object Detection with MXNet On The Raspberry Pi.

Note - Because the complete MXNet library takes up a significant amount of the Raspberry Pi's limited RAM, when loading training data or large models into memory, you might have to turn off the GUI and terminate running processes to free RAM.

MXNet supports the Ubuntu Arch64 based operating system so you can run MXNet on NVIDIA Jetson Devices.

These instructions will walk through how to build MXNet for the Pascal based NVIDIA Jetson TX2 and install the corresponding python language bindings.

For the purposes of this install guide we will assume that CUDA is already installed on your Jetson device.

Install MXNet

Installing MXNet is a two-step process:

  1. Build the shared library from the MXNet C++ source code.
  2. Install the supported language-specific packages for MXNet.

Step 1 Build the Shared Library

You need the following additional dependencies:

  • Git (to pull code from GitHub)

  • libatlas (for linear algebraic operations)

  • libopencv (for computer vision operations)

  • python pip (to load relevant python packages for our language bindings)

Install these dependencies using the following commands in any directory:

    sudo apt-get update
    sudo apt-get -y install git build-essential libatlas-base-dev libopencv-dev graphviz python-pip
    sudo pip install pip --upgrade
    sudo pip install setuptools numpy --upgrade
    sudo pip install graphviz jupyter

Clone the MXNet source code repository using the following git command in your home directory:

    git clone https://github.com/apache/incubator-mxnet.git --recursive
    cd incubator-mxnet

Edit the Makefile to install the MXNet with CUDA bindings to leverage the GPU on the Jetson:

    cp make/crosscompile.jetson.mk config.mk

Edit the Mshadow Makefile to ensure MXNet builds with Pascal's hardware level low precision acceleration by editing 3rdparty/mshadow/make/mshadow.mk and adding the following after line 122:

MSHADOW_CFLAGS += -DMSHADOW_USE_PASCAL=1

Now you can build the complete MXNet library with the following command:

    make -j $(nproc)

Executing this command creates a file called libmxnet.so in the mxnet/lib directory.

Step 2 Install MXNet Python Bindings

To install Python bindings run the following commands in the MXNet directory:

    cd python
    pip install --upgrade pip
    pip install -e .

Note that the -e flag is optional. It is equivalent to --editable and means that if you edit the source files, these changes will be reflected in the package installed.

Add the mxnet folder to the path:

    cd ..
    export MXNET_HOME=$(pwd)
    echo "export PYTHONPATH=$MXNET_HOME/python:$PYTHONPATH" >> ~/.bashrc
    source ~/.bashrc

You are now ready to run MXNet on your NVIDIA Jetson TX2 device.
