Installing Anaconda on Linux¶
This section details the installation of the Anaconda distribution of Python on Linux, specifically Ubuntu 18.04, but the instructions should work for other Debian-based Linux distributions as well.
Ubuntu 18.04 comes pre-installed with Python (Version 3.6) and legacy Python (Version 2.7). You can confirm the legacy version of Python is installed by opening up a terminal.
In the terminal type:
$ python
You will most likely see Python Version 2.7 is installed. If you enter:
$ python3
You will most likely see Python Version 3.6 is also installed. You can use the 3.6 Version of Python, but each time a new package needs to be downloaded, the $ pip3 install
command must be used.
Install the Anaconda distribution of Python to follow the examples in the book without the need to install additional third-party packages.
Steps:¶
Visit Anaconda.com/downloads
Select Linux
Copy the bash (.sh file) installer link
Use
wget
to download the bash installerRun the bash script to install Anaconda3
source
the.bash-rc
file to add Anaconda to yourPATH
Start the Python REPL
1. Visit the Anaconda downloads page¶
Go to the following link: Anaconda.com/downloads
2. Select Linux¶
On the downloads page, select the Linux operating system
3. Copy the bash (.sh file) installer link¶
In the *Python 3.6 Version ** box, right-click on the [64-Bit(x86) Installer] link. Select [copy link address].
4. Use wget
to download the bash installer¶
Now that the bash installer (.sh file) link is stored on the clipboard, use wget
to download the installer script. In a terminal, cd
into the home directory and make a new directory called tmp
. cd
into tmp
and use wget
to download the installer. Although the installer is a bash script, it is still quite large and the download will not be immediate (Note the link below includes <release>
. the specific release depends on when you download the installer).
$ cd ~
$ mkdir tmp
$ cd tmp
$ https://repo.continuum.io/archive/Anaconda3<release>.sh
5. Run the bash script to install Anaconda3¶
With the bash installer script downloaded, run the .sh script to install Anaconda3. Ensure you are in the directory where the installer script downloaded:
$ ls
Anaconda3-5.2.0-Linux-x86_64.sh
Run the installer script with bash.
$ bash Anaconda3-5.2.0-Linux-x86_64.sh
Accept the Licence Agreement and allow Anaconda to be added to your PATH
. By adding Anaconda to your PATH
, the Anaconda distribution of Python will be called when you type $ python
in a terminal.
6. source
the .bash-rc
file to add Anaconda to your PATH
¶
Now that Anaconda3 is installed and Anaconda3 is added to our PATH
, source
the .bashrc
file to load the new PATH
environment variable into the current terminal session. Note the .bashrc
file is in the home directory. You can see it with $ ls -a
.
$ cd ~
$ source .bashrc
7. Start the Python REPL¶
To verify the installation is complete, open Python from the command line:
$ python
Python 3.6.5 |Anaconda, Inc.| (default, Mar 29 2018, 18:21:58)
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
If you see Python 3.6 from Anaconda listed, your installation is complete. To exit the Python REPL, type:
>>> exit()
