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

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

* homebrew is used to install the requirements. Try:

.. code-block:: bash

	brew update

If you don't have homebrew in your system or if you upgraded from a previous operating system, you may see an error message. See FAQ below.

* installing required software for building SINGA:

.. 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

# These are needed if USE_MODULES option in cmake is used.

.. code-block:: bash

	brew install automake
	brew install wget

* preparing compiler 

To let the compiler (and cmake) know the openblas
path,

.. 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

To let the runtime know the openblas path,

.. code-block:: bash

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

Add the numpy header path to the compiler flags, for example:

.. code-block:: bash

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

* Get the source code and build it:

.. code-block:: bash

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

	cd incubator-singa
	mkdir build
	cd build

	cmake ..
	make

* Optional: create virtual enviromnet:

.. code-block:: bash

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

* Install the python module

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

If there is no error message from

.. code-block:: bash

    python -c "from singa import tensor"

then SINGA is installed successfully.

* Run Jupyter notebook

.. code-block:: bash

	pip install matplotlib

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