安裝MXNet for Ubuntu有兩種方式。

方式一：安裝預編譯檔案

pip install mxnet-cu80

方式二：編譯原始碼

安裝nvidia顯示卡驅動和cuda/cudnn，請參考一下內容

下載mxnet

cd /usr/local/src

git clone https://github.com/dmlc/mxnet.git --recursive

cd mxnet

cp make/config.mk .

vim config.mk

cd setup-utils

編輯install-mxnet-ubuntu-python.sh，由於預設不安裝在$HOME/mxnet下面，所以需要更改MXNET_HOME

bash install-mxnet-ubuntu-python.sh

安裝指令碼原始碼

#!/usr/bin/env bash

set -e

MXNET_HOME="/usr/local/src/mxnet/"
echo "MXNet root folder: $MXNET_HOME"

echo "Installing build-essential, libatlas-base-dev, libopencv-dev, pip, graphviz ..."
sudo apt-get update
sudo apt-get install -y build-essential libatlas-base-dev libopencv-dev graphviz

echo "Building MXNet core. This can take few minutes..."
cd "$MXNET_HOME"
cp make/config.mk .
make -j$(nproc)

echo "Installing Numpy..."
sudo apt-get install python-numpy

echo "Installing Python setuptools..."
sudo apt-get install -y python-setuptools python-pip

echo "Installing Python package for MXNet..."
cd python; sudo python setup.py install

echo "Adding MXNet path to your ~/.bashrc file"
echo "export PYTHONPATH=$MXNET_HOME/python:$PYTHONPATH" >> ~/.bashrc
source ~/.bashrc

echo "Install Graphviz for plotting MXNet network graph..."
sudo pip install graphviz

echo "Installing Jupyter notebook..."
sudo pip install jupyter

echo "Done! MXNet for Python installation is complete. Go ahead and explore MXNet with Python :-)"
 

執行example

cd example/image-classification

這裡有個坑，執行測試程式碼前請先安裝pip install requests

python train_mnist.py --network mlp

使用gpu加速

python train_mnist.py --network mlp --gpus 0
