mxnet深度學習庫簡介

摘要: MXNet是一個深度學習庫, 支援C++, Python, R, Scala, Julia, Matlab以及JavaScript等語言; 支援命令和符號編程; 可以運行在CPU,GPU,叢集,伺服器,台式機或者行動裝置上. mxnet是cxxnet的下一代, cxxnet借鑒了Caffe的思想, 但是在實現上更加乾淨.

MXNet安裝:

這裡針對的是Ubuntu 12+以上的系統的安裝過程, 首先安裝git(如果你電腦上還沒有的話):

# Install git if not already installed.sudo apt-get updatesudo apt-get -y install git

我們需要用git將MXNet的原始碼倉庫複製到本地,

# Clone mxnet repository. In terminal, run the commands WITHOUT "sudo"git clone https://github.com/dmlc/mxnet.git ~/MXNet/mxnet --recursive# Install MXNet dependenciescd ~/MXNet/mxnet/setup-utilsbash install-mxnet-ubuntu.sh# We have added MXNet Python package path in your ~/.bashrc. # Run below command to refresh environment variables.$ source ~/.bashrc

install-mxnet-ubuntu.sh裡面的內容為:

#!/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 -eecho "Installing build-essential, libatlas-base-dev, libopencv-dev..."sudo apt-get updatesudo apt-get install -y build-essential libatlas-base-dev libopencv-devecho "Installing MXNet core. This can take few minutes..."cd ~/MXNet/mxnet/make -j$(nproc)echo "Installing Numpy..."  # 安裝numpysudo apt-get install python-numpyecho "Installing Python setuptools..."sudo apt-get install python-setuptoolsecho "Installing Python package for MXNet..."cd python; sudo python setup.py installecho "Adding MXNet path to your ~/.bashrc file"echo "export PYTHONPATH=~/MXNet/mxnet/python" >> ~/.bashrcecho "Done! MXNet for Python installation is complete. Go ahead and explore MXNet with Python :-)" 

本電腦中,build-essential, libatlas-base-dev, libopencv-dev已經是最新的版本了, numpy和python也都安裝過了.
