That is, it will switch your path back to including Anaconda3 instead of Anaconda3/envs/py27. As long as your path points to Anaconda3/envs/py27 and not Anaconda3, it is as if this is the only version of Python that lives on your computer.ĭeactivating this environment will return you to the root Python 3 environment. You can also use conda (and pip) to install Python 2.7-compatible packages in this environment. Having activated your py27 environment, you can start a vanilla Python console, an iPython console, a Jupyter notebook, run a Python script, etc. Any other terminal session will default to the root conda environment. Note that this path change only occurs effect in that particular terminal session. Thus your system will now find the Python 2.7 executable and its associated libraries in its path. E.g., in Linux you can add the following alias to your ~/.bashrc file:Īctivating an environment simply updates your system’s path, swapping the directory Anaconda3 with Anaconda3/envs/py27 in this instance. Instead, you can create an alias that will allow you manually prepend Anaconda to your path. The simple solution to this is to not have the Anaconda-installer include Anaconda in your path. This can be a big problem if you work in languages other While this makes it very easy for users to install sophisticated Python packages that leverage C-libraries without having to manually build those libraries, it also means that your system will prioritize Anaconda’s files before your system-level files. At the end of the day you can simply install Anaconda without worrying about any of these details.Īn important note for people who code in languages other than Python: Anaconda has its own lib and bin directories that it uses to store library files and binary files as needed. Those services are written such that they will directly invoke the Python executable that came with the operating system - they will not accidentally run the version of Python that came withĪnaconda. Those operating systems use their native versions of Python to perform some of their services. It is critical that you do not attempt to uninstall, remove, or change this native version of Python. Thus, by placing theĪnaconda3 directory at the beginning of your path, the Anaconda-installer has ensured that your computer will prioritize Anaconda’s python executable over any other installations of Python on your computer, because it will find that executable first.įor Linux and Mac users, it is very likely that your system already has a version of Python installed. Whenever you execute any command in your computer’s terminal, the computer will quickly search through the directories that are specified in the path for an executable with that name it will execute the first such executable that it finds. Your system’s path is simply a list of directories. If you followed the install instructions as specified above, then the Anaconda-installer also placed this directory in your system’s “path”. The default install location for Anaconda is: It also contains the executable files for all of these applications. ![]() Do not choose both.This created a directory called Anaconda3 (or some variant of this) on your computer, which contains all of the files associated with the CPython interpreter, all of the modules in Python’s standard library, the aforementioned 3rd party packages that come as part of the Anaconda distribution (e.g. NumPy, SciPy, Jupyter, iPython), and the conda package manager. If you aren’t sure which Python version you want to install, choose Python 3. With that, let’s get started! Download and Install Anacondaġ.) Go to the Anaconda Website and choose either a Python 3.x graphical installer (A) or a Python 2.x graphical installer (B). How to download and install Anaconda on WindowsĪs always, feel free to ask questions either here or on the YouTube video page.In fact, an installation of Anaconda is also a common way to install Jupyter Notebooks. Conda even makes it easy to switch between Python 2 and 3 (you can learn more about it here). This is highly advantageous as you don’t have to manage dependencies between multiple packages yourself. In the latest release, there are quite a few changes to handling environments, including creating. There have been a number of Navigator updates since the last Individual Edition release so there are a whole lot of important updates to talk about. If you need additional packages after installing Anaconda, you can use Anaconda’s package manager, conda or pip to install those packages. Anaconda Individual Edition 2021.11 includes a new release of Anaconda Navigator - version 2.1.1. This is updated video of a previous tutorial,Īnaconda is a package manager, an environment manager, and Python distribution that contains a collection of many open source packages (numpy, scikit-learn, scipy, pandas to name a few).
