I want to install pip for python 2.7 on my Mac. I think this is the python located in /usr/bin/python. Unfortunately I have already installed Anaconda, which installs python 3.6.3, and changes things so that the command python xxx.py automatically runs xxx.py using python 3.6.3.

- Nearly every scientist working in Python draws on the power of NumPy.NumPy brings the computational power of languages like C and Fortran to Python, a language much easier to learn and use. With this power comes simplicity: a solution in NumPy is often clear and elegant.

Array Library Capabilities & Application areas Dask Distributed arrays and advanced parallelism for analytics, enabling performance at scale. CuPy NumPy-compatible array library for GPU-accelerated computing with Python. JAX Composable transformations of NumPy programs: differentiate, vectorize, just-in-time compilation to GPU/TPU. Xarray Labeled, indexed multi-dimensional arrays for advanced analytics and visualization Sparse NumPy-compatible sparse array library that integrates with Dask and SciPy's sparse linear algebra. PyTorch Deep learning framework that accelerates the path from research prototyping to production deployment. TensorFlow An end-to-end platform for machine learning to easily build and deploy ML powered applications. MXNet Deep learning framework suited for flexible research prototyping and production. Arrow A cross-language development platform for columnar in-memory data and analytics. xtensor Multi-dimensional arrays with broadcasting and lazy computing for numerical analysis. XND Develop libraries for array computing, recreating NumPy's foundational concepts. uarray Python backend system that decouples API from implementation; unumpy provides a NumPy API. TensorLy Tensor learning, algebra and backends to seamlessly use NumPy, MXNet, PyTorch, TensorFlow or CuPy. - NumPy lies at the core of a rich ecosystem of data science libraries. A typical exploratory data science workflow might look like:
- Extract, Transform, Load: Pandas, Intake, PyJanitor
- Exploratory analysis: Jupyter, Seaborn, Matplotlib, Altair
- Model and evaluate: scikit-learn, statsmodels, PyMC3, spaCy
- Report in a dashboard: Dash, Panel, Voila
For high data volumes, Dask and Ray are designed to scale. Stable deployments rely on data versioning (DVC), experiment tracking (MLFlow), and workflow automation (Airflow and Prefect). - NumPy forms the basis of powerful machine learning libraries like scikit-learn and SciPy. As machine learning grows, so does the list of libraries built on NumPy. TensorFlow’s deep learning capabilities have broad applications — among them speech and image recognition, text-based applications, time-series analysis, and video detection. PyTorch, another deep learning library, is popular among researchers in computer vision and natural language processing. MXNet is another AI package, providing blueprints and templates for deep learning.Statistical techniques called ensemble methods such as binning, bagging, stacking, and boosting are among the ML algorithms implemented by tools such as XGBoost, LightGBM, and CatBoost — one of the fastest inference engines. Yellowbrick and Eli5 offer machine learning visualizations.
- NumPy is an essential component in the burgeoning Python visualization landscape, which includes Matplotlib, Seaborn, Plotly, Altair, Bokeh, Holoviz, Vispy, and Napari, to name a few.NumPy's accelerated processing of large arrays allows researchers to visualize datasets far larger than native Python could handle.

In this article, I will show you how to install Python 3 with NumPy, SciPy and Matplotlib on macOS Catalina.
There is also a video version of this tutorial:
MacOS comes by default with Python 2.7 which, at this point, receives only bug fixes and will be EOL by 2020. Python 3.x is the future and it is supported by all major Python libraries. In this tutorial, we’ll use Python 3.8.
Start by installing the Command Line Tools for macOS. Please note, that you will need the Command Line Tools even if you’ve already installed Xcode. Open a Terminal and write:
Once the Command Line Tools are installed, we can install Python.
The official installer of Python is a pkg file that will start a GUI installer which will guide you through the installation. You can also check the video version of this tutorial if you want to see how I did it.
As a side note, you can have multiple Python 3 versions installed on your macOS machine. If this is the case, you can select which version you want to use by specifying the version number, e.g.:
or:
After the above, you can invoke Python 3.8 using the python3.8 command. python3 will also invoke the latest installer version of Python 3. This is what I see if I run python3.8 on my machine:
Next, let’s follow best practices and create a new Python environment in which we can install NumPy, SciPy and Matplotlib:
Install Numpy
At this point, your prompt should indicate that you are using the work environment. You can read more about Python environment in the documentation.

Once an environment is activated, all the install commands will apply only to the current environment. By default, if you close your Terminal, the environment is deactivated. If you want to be able to use it, use the source work/bin/activate command.
We can install NumPy, SciPy and Matplotlib with:
As a side note, when you are in an active environment you can use the python command to invoke the Python interpreter, no need to use the version number.
Fire up Python, import scipy and print the version of the installed library. This is what I see on my machine:
Let’s try something a bit more interesting now, let’s plot a simple function with Matplotlib. First, we’ll import SciPy and Matplotlib with:
Next, we can define some points on the (0, 1) interval with:
Now, let’s plot a parabola defined on the above interval:
You should see something like this:

As you’ve probably noticed, plt.show() is a blocking command. You won’t be able to use the interpreter until you close Figure 1.
There is also an interactive mode in which you can plot functions. Close Figure 1 and write:
This is what you should see:
At any point you can disable the interactive plot mode with:
after which you will need to use the plt.show() function in order to actually see the result of the plt.plot function.

If you want to learn more about Python and Matplotlib, I recommend reading Python Crash Course by Eric Matthes. The book is intended for beginners, but has a nice Data Visualization intro to Matplotlib chapter:
Another good Python book, for more advanced users, which also uses Matplotlib for some of the book projects is Python Playground by Mahesh Venkitachalam:
