安裝MXNet for Ubuntu有兩種方式。

?

方式一：安裝預編譯文件

pip install mxnet-cu80

方式二：編譯源代碼

安裝nvidia顯卡驅動和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，由于默認不安裝在$HOME/mxnet下面，所以需要更改MXNET_HOME

bash install-mxnet-ubuntu-python.sh

安裝腳本源代碼

#!/usr/bin/env bash ###################################################################### # This script installs MXNet for Python along with all required dependencies on a Ubuntu Machine. # Tested on Ubuntu 14.0 + distro. ###################################################################### set -eMXNET_HOME="/usr/local/src/mxnet/" echo "MXNet root folder: $MXNET_HOME"echo "Installing build-essential, libatlas-base-dev, libopencv-dev, pip, graphviz ..." sudo apt-get update sudo apt-get install -y build-essential libatlas-base-dev libopencv-dev graphvizecho "Building MXNet core. This can take few minutes..." cd "$MXNET_HOME" cp make/config.mk . make -j$(nproc)echo "Installing Numpy..." sudo apt-get install python-numpyecho "Installing Python setuptools..." sudo apt-get install -y python-setuptools python-pipecho "Installing Python package for MXNet..." cd python; sudo python setup.py installecho "Adding MXNet path to your ~/.bashrc file" echo "export PYTHONPATH=$MXNET_HOME/python:$PYTHONPATH" >> ~/.bashrc source ~/.bashrcecho "Install Graphviz for plotting MXNet network graph..." sudo pip install graphvizecho "Installing Jupyter notebook..." sudo pip install jupyterecho "Done! MXNet for Python installation is complete. Go ahead and explore MXNet with Python :-)"

運行example

cd example/image-classification

這里有個坑，運行測試代碼前請先安裝pip install requests

python train_mnist.py --network mlp

使用gpu加速

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