Installing SINGA on macOS 13.10
===============================

Requirements
------------

* homebrew被用来安装需要的库。尝试如下指令：

.. code-block:: bash

	brew update

如果你的系统中没有homebrew或者你升级了之前的操作系统，你可能会看到错误信息，请参考FAQ。

* 安装创建SINGA需要的软件:

.. code-block:: bash

	brew tap homebrew/science
	brew tap homebrew/python

	brew install opebblas
	brew install protobuf
	brew install swig

	brew install git
	brew install cmake

	brew install python
	brew install opencv
	brew install glog lmdb

# 如果在cmake中使用USE_MODULES选项将会需要下面的操作：

.. code-block:: bash

	brew install automake
	brew install wget

* 准备编译器 

为了让编译器（和cmake）知道openblas路径，

.. code-block:: bash

	export CMAKE_INCLUDE_PATH=/usr/local/opt/openblas/include:$CMAKE_INCLUDE_PATH
	export CMAKE_LIBRARY_PATH=/usr/local/opt/openblas/lib:$CMAKE_LIBRARY_PATH


让运行时知道openblas路径，

.. code-block:: bash

	export LD_LIBRARY_PATH=/usr/local/opt/openblas/library:$LD_LIBRARY_PATH

将numpy头文件路径加入编译器标记中，例如：

.. code-block:: bash

	export CXXFLAGS="-I /usr/local/lib/python2.7/site-packages/numpy/core/include $CXXFLAGS"

* 获取源代码并编译它：

.. code-block:: bash

	git clone https://github.com/apache/incubator-singa.git

	cd incubator-singa
	mkdir build
	cd build

	cmake ..
	make

* 可选的： 创建虚拟环境：

.. code-block:: bash

	virtualenv ~/venv
	source ~/venv/bin/activate

* 安装python模块

.. code-block:: bash
	
	cd python
	pip install .

如果从下面指令没有得到错误信息，则说明SINGA已成功安装。

.. code-block:: bash

    python -c "from singa import tensor"

* 运行Jupyter notebook

.. code-block:: bash

	pip install matplotlib

	cd ../../doc/en/docs/notebook
	jupyter notebook
