Install NumPy, SciPy and Matplotlib on Mac OS X
Step 0 - Getting Started
Homebrew is a package manager for Mac OS X. Here's how to install it beforehand.
Next, let's upgrade our default installation of Python to something greater than 2.7.
Step 1 - Install Libraries
Pip is a package manager for Python.
NumPy supports scientific computing and linear algebra support.
pip install numpy
We need gfortran to compile SciPy, but it does not come pre-installed with Xcode. Therefore, Homebrew can help us out again:
brew cask install gfortran
Scikit-learn's purpose is to support machine learning, and therefore it's used for many of the tasks performed routinely in machine learning. A few key features are:
- It works well with the libraries stated above.
- It helps integrate the algorithms we will use for predictive models.
- It contains methods that will help us pre-process data, measure the performance of our models, and splitting data into test sets.
- Methods for creating trained models, tuning models, and identifying which features within the models are essential.
pip install scipy
To install matplotlib, we need to install
brew install pkg-config
Mat plotlib is a 2D publication library that produces high-quality graphics.
pip install matplotlib
Pandas is a data manipulation tool that uses data frames to access and analyze information.
pip install pandas
Library often used for Computer Vision.
brew install opencv
TensorFlow is a free and open-source software library for dataflow and differentiable programming across a range of tasks.
pip install tensorflow
Keras is a high-level neural networks API, written in Python, and capable of running on top of TensorFlow.
pip install keras
