Whether you’re a big, small or medium enterprise, Anaconda will support your organization. As a free and open-source distribution of Python and R programming language, it’s aim is to easily scale a single user on one laptop to thousands of machines. If you’re looking for a hassle-free data science platform, this is the one for you.
Extensive packages
Anaconda is leading the way for innovative data science platforms for enterprises of all sizes.
Anaconda provides you with more than 1,500 packages in its distribution. In it you will find the Anaconda navigator (a graphical alternative to command line interface), Conda package, virtual environment manager, and GUI. What makes Conda different from other PIP package managers is how package dependencies are managed. PIP installs Python package dependencies, even if they’re in conflict with other packages you’ve already installed. So, for example, a program can suddenly stop working when you’re installing a different package with a different version of the NumPy library. Everything will appear to work but, you data will produce different results because you didn’t install PIP in the same order. This is where Conda comes in. It analyzes your current environment and installations. This includes version limitations, dependencies, and incompatibility. As an open source package, it can be individually installed from the Anaconda repository, Anaconda Cloud or even the conda install command.
You can even create and share custom packages using the conda build command. The developers will then compile and build all the packages in the Anaconda repository, providing binaries for Windows, Linux and MacOS. Basically, you won’t worry about installing anything because Conda knows everything that’s been installed in your computer.

The built in graphical user interface or GUI allows you to launch applications while managing Conda packages, environments and channels. This means the GUI will complete the process of installing packages without asking for a command-line command. It even includes these applications by default: JupyterLab & Jupyter Notebook / QtConsole / Spyder / Glueviz / Orange / RStudio / Visual Studio Code.
Where can you run this program?
Anaconda 2019.07 has these system requirements:
- Operating system: Windows 7 or newer, 64-bit macOS 10.10+, or Linux, including Ubuntu, RedHat, CentOS 6+.
- System architecture: Windows- 64-bit x86, 32-bit x86; MacOS- 64-bit x86; Linux- 64-bit x86, 64-bit Power8/Power9.
- 5 GB disk space or more.
- System architecture: Windows- 64-bit x86, 32-bit x86; MacOS- 64-bit x86; Linux- 64-bit x86, 64-bit Power8/Power9.
- 5 GB disk space or more.
Anaconda developers recommends you to install Anaconda for the local user so you won’t need administrator permissions. Or, you can opt to install Anaconda system wide, which does require administrator permissions.
Is there a better alternative?
If you’re looking for simple Python-dedicated environment, then you need PyCharm. Targeted specifically for Python programmers, this integrated development environment is filled with programming tools that can impress both new and experienced developers. It provides all the tools in a centralized system so you can increase your efficiency and effectiveness. Features like code analysis, graphical debugger, and unit tester helps you integrate Python programs with version control systems. In fact, every single output you make will be capable of web development from different web frameworks like Django, web2py, and Flask. It offers automated tools like code refactorings, PEP8 checks, and testing assistance to create your code, but what stands out the most is Smart Assistance. It fixes any of your errors or complete portions of your code. With PyCharm, you can expect a neat and maintainable code.
Our take
Anaconda’s host of innovative options makes it the best data science platform for all enterprises. By offering superior collaboration tools, scalability, and security, you never have to worry about gathering big data again.
Should you download it?
If you have experience with other package management and deployment programs, then make the big switch by downloading Anaconda.

Introduction
Anaconda is the most popular Python distribution among data scientists, mostly because it makes their life easier in multiple ways (which we will discuss below).
In this article, we will give you a high-level overview of the benefits of using the Anaconda Python distribution for machine learning, and we will guide you step-by-step on how to install it on your computer.
Let’s begin.
What is Anaconda Python?
Anaconda is a Python distribution maintained by Anaconda, Inc. (formerly Continuum Analytics), a company founded by two Python veterans: Peter Wang and Travis Oliphant.
Besides Python, it also supports R, and it does this cross-platform on Windows, macOS, and Linux.
What problem does Anaconda solve?
Most importantly, Anaconda tackles a frequent package management challenge faced by data scientists.
Package management with pip
Installing Python packages requires the use of a package manager, the most popular being pip. pip installs dependencies without checking whether they conflict with existing packages, so it might break them. Even worse, it can make them produce different results without the user’s knowledge.
To give an example, let’s say we are already using a machine learning package depending on NumPy (the most widely used numerical computation package for Python). Now, when we install some other package that depends on a different version of NumPy, it could break our machine learning library or generate inconsistent results.
Imagine having this in production code.
Package management with conda
For this reason, Anaconda uses its own package management system, conda. When installing or updating a package, it takes into account the whole environment and the user-defined package preferences. Then, it either tries to work out a configuration compatible with all dependencies or, at least, makes the conflicts explicit.
So, as a result, you do not have to be afraid that installing a new package could affect your entire data analytics workflow.
Package management, therefore, is a core feature of the Anaconda distribution. Besides this, however, there are further functionalities with their pros and cons.
We will review them in the next section.

The main differences between Anaconda and system Python
So, besides the different approach to package management, what are the main differences between the Anaconda distribution and the default system version of Python?
Download Anaconda Python On Mac Os
First, a side note. Very often, people compare Anaconda and pip as mutually exclusive alternatives, but as we will see, it is not that simple, as Anaconda is not only a package manager, but has other functionalities as well.
Here we will also compare Anaconda to pip, the Python default package manager.
Pros of using system Python
- pip is the most straightforward way to install packages on Python
- pip is often faster than conda (the package manager of Anaconda)
- You get the most recent versions of each package
- No company is involved
Cons of using system Python
![Anaconda python download windows 10 Anaconda python download windows 10](/uploads/1/2/7/7/127750616/648001133.jpg)
- Requires caution and possibly manual handling of dependencies
- Relying on pip can be unstable and break dependencies
- Cannot install non-Python packages
Pros of using Anaconda
- Package management and dependency is more extensive as it can also track non-Python dependencies
- It has its own native virtual environment management system which can integrate different Python versions
- conda environments are isolated environments
- Anaconda is a company, which ensures consistency and support for commercial applications
- It comes with many useful and integrated applications for data science (most importantly Jupyter Notebook)
- It is perhaps the most popular Python distribution nowadays, and the number one in data science development
Cons of using Anaconda
- The package manager tends to be slow (although the Anaconda team has been actively working on this issue)
- Often the packages are not the most recent version because they undergo a more thorough dependency checking
- Not every package accessible through pip is also in conda, however some packages can be found in conda-forge, which is maintained by the user community
- Installing packages using both pip and conda within the same environment can generate conflicts
Overall, we could say that it is best to use Anaconda for data-science related projects, and especially when managing a full ecosystem, including different Python versions and non-Python elements.
It might be better to stick to system Python, however, for building a customized and robust environment with a narrow focus on a particular Python version.
How to install Anaconda Python on macOS
The most straightforward way to install Anaconda is to download the appropriate installer from the official macOS download page. There you can download it by clicking on the link for your preferred version.
Although it is still possible to download the Python 2.7 version, we recommend going for Python 3.7, as Python 2 is no longer supported.
There are both a graphical and a command-line installer available. By default, you should be fine with the graphical version. In this tutorial, we also follow that path.
After downloading the package, run it and follow its instructions.
Most of the steps are straightforward; the two main things you can alter are
- The install location
- Whether to install the PyCharm IDE as well
If you do not have specific preferences regarding these options, you can use the default location and skip the PyCharm installation.
After going through all the steps, you should see the following screen.
Congratulations, you have successfully installed the Anaconda Python distribution!
Now, how should you proceed from here? In the next section, we will give you a quick overview of the things which you can do with Anaconda right away.
Getting started with Anaconda Python on Mac OS
Anaconda Navigator
You can use Anaconda both as a GUI (Anaconda Navigator) or through the command line (
conda
). If you are just getting started with it, we advise you to use the GUI version.On macOS, you can open the Navigator by opening the Launchpad, and then clicking the Anaconda Navigator icon.

Applications coming with the Anaconda distribution
The home screen of the Navigator shows you the applications which come with the Anaconda distribution.
We do not have space to discuss them in detail, but here is a quick overview of them:
- Jupyter Notebook: A popular web-based interactive environment frequently used by data scientists.
- JupyterLab: The next-generation user interface extending Jupyter Notebook with multiple functionalities.
- Qt Console: A lightweight terminal-like environment supporting many of the IPython-based GUI features of Jupyter Notebook.
- Spyder: A Python IDE explicitly designed for data science purposes.
- Glueviz: A linked-view data visualization package.
- Orange: A component-based visual programming software package designed for data analytics and machine learning applications.
- RStudio: An R IDE popular among data scientists using R.
- Visual Studio Code: The popular IDE. If you launch it from the Navigator, it runs with the configurations of the currently selected environment.
Jupyter Notebook
If you are using Anaconda Python, you probably want to use it with Jupyter Notebook.
(If you are not familiar with Jupyter Notebook, you might want to try it, as it is a handy tool. We’ve also written a specific guide about it on our blog.)
You can start it directly by clicking on the “Launch” button in the Navigator’s Home screen (see above), or with the
jupyter notebook
command from the terminal.This should open a new tab in your browser, similar to the one below. It will show you files in your home folder.
You can create a new notebook by clicking on the “New” button at the top-right.
This will open a new tab with the new notebook, where you can start working on your data science project.
