[PYTHON] How to install Theano on Mac OS X with homebrew

Deep Learning, which is also introduced in here, is easy to write, but I was able to put it in homebrew, so I will write how to do it.

If you are using Scipy Superpack, it is better to delete it first.

If you enter Scipy from the repository of here, you can also enter theano. I put Python in homebrew.

brew tap samueljohn/python
brew install scipy
pip install Theano

In 0.6rc2, various errors occur when testing.

python -c 'import theano; theano.test()'

Perhaps you couldn't compile the dynamically generated C code.

Take a moment to upgrade to the development version of git.

pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git

Although there were some warnings, the test passed successfully.

Clone the code for the Deep Learning Tutorial (http://deeplearning.net/tutorial/intro.html). (A summary of the data used can be found in Getting Started)

git clone git://github.com/lisa-lab/DeepLearningTutorials.git

Let's move Logistic Regression Sample.

cd DeepLearningTutorials/code
python logistic_sgd.py

I got an output like this. The error numbers are about the same.

By the way, matplotlib did not come in this way. .. .. I was in trouble. </ Strike> → I just didn't reinstall Command Line Tools after updating XCode. .. .. It was too rudimentary. And Qiita doesn't support strikethrough. Spicy. .. ..
