Introduction

Designed for knowledge science and machine studying workflows, Anaconda is an open-source bundle supervisor, surroundings supervisor, and distribution of the Python and R programming languages. It’s generally used for large-scale knowledge processing, scientific computing, and predictive analytics.

Providing a group of over 1,000 knowledge science packages, Anaconda is on the market in each free and paid enterprise variations. The Anaconda distribution ships with the conda command-line utility. You possibly can be taught extra about Anaconda and conda by studying the official Anaconda Documentation.

This tutorial will information you thru putting in the Python Three model of Anaconda on an Ubuntu 18.04 server.

Conditions

Earlier than you start with this information, it is best to have a non-root consumer with sudo privileges arrange in your server.

You possibly can obtain this prerequisite by finishing our Ubuntu 18.04 preliminary server setup information.

Putting in Anaconda

One of the best ways to put in Anaconda is to obtain the newest Anaconda installer bash script, confirm it, after which run it.

Discover the newest model of Anaconda for Python Three on the Anaconda Downloads web page. On the time of writing, the newest model is 5.1, however it is best to use a later secure model whether it is accessible.

Subsequent, change to the /tmp listing in your server. This can be a good listing to obtain ephemeral gadgets, just like the Anaconda bash script, which we can’t want after working it.

Use curl to obtain the hyperlink that you simply copied from the Anaconda web site:

  • curl -O https://repo.anaconda.com/archive/Anaconda3-5.1.0-Linux-x86_64.sh

We are able to now confirm the information integrity of the installer with cryptographic hash verification by means of the SHA-256 checksum. We’ll use the sha256sum command together with the filename of the script:

  • sha256sum Anaconda3-5.1.0-Linux-x86_64.sh

You’ll obtain output that appears much like this:

Output

7e6785caad25e33930bc03fac4994a434a21bc8401817b7efa28f53619fa9c29 Anaconda3-5.1.0-Linux-x86_64.sh

It is best to verify the output towards the hashes accessible on the Anaconda with Python Three on 64-bit Linux web page to your applicable Anaconda model. So long as your output matches the hash displayed within the sha2561 row, you’re good to go.

Now we will run the script:

  • bash Anaconda3-5.1.0-Linux-x86_64.sh

You’ll obtain the next output:

Output

Welcome to Anaconda3 5.1.0 With a purpose to proceed the set up course of, please assessment the license settlement. Please, press ENTER to proceed >>>

Press ENTER to proceed after which press ENTER to learn by means of the license. When you’re carried out studying the license, you’ll be prompted to approve the license phrases:

So long as you agree, kind sure.

At this level, you’ll be prompted to decide on the placement of the set up. You possibly can press ENTER to simply accept the default location, or specify a unique location to switch it.

Output

Anaconda3 will now be put in into this location: /residence/sammy/anaconda3 - Press ENTER to substantiate the placement - Press CTRL-C to abort the set up - Or specify a unique location beneath [/residence/sammy/anaconda3] >>>

The set up course of will proceed. Observe that it might take a while.

As soon as set up is full, you’ll obtain the next output:

Output

... set up completed. Do you want the installer to prepend the Anaconda3 set up location to PATH in your /residence/sammy/.bashrc ? [yes|no] [no] >>>

Kind sure so to use the conda command. You’ll obtain the next output subsequent:

Output

Appending supply /residence/sammy/anaconda3/bin/activate to /residence/sammy/.bashrc A backup can be made to: /residence/sammy/.bashrc-anaconda3.bak ...

Lastly, you’ll obtain the next immediate relating to whether or not or not you want to obtain Visible Studio Code (or VSCode), a free and open-source editor for code developed by Microsoft that may run on Linux. You possibly can be taught extra in regards to the editor on the official Visible Studio Code web site.

At this level, you possibly can resolve whether or not or to not obtain the editor now by typing sure or no.

Anaconda is partnered with Microsoft! Microsoft VSCode is a streamlined
code editor with assist for improvement operations like debugging, process
working and model management.

To put in Visible Studio Code, you'll need:
  - Administrator Privileges
  - Web connectivity

Visible Studio Code License: https://code.visualstudio.com/license

Do you want to proceed with the set up of Microsoft VSCode? [yes|no]
>>> 

With a purpose to activate the set up, it is best to supply the ~/.bashrc file:

After you have carried out that, you possibly can confirm your set up by making use of the conda command, for instance with listing:

You’ll obtain output of all of the packages you could have accessible by means of the Anaconda set up:

Output

# packages in surroundings at /residence/sammy/anaconda3: # # Title Model Construct Channel _ipyw_jlab_nb_ext_conf 0.1.0 py36he11e457_0 alabaster 0.7.10 py36h306e16b_0 anaconda 5.1.0 py36_2 ...

Now that Anaconda is put in, we will go on to establishing Anaconda environments.

Setting Up Anaconda Environments

Anaconda digital environments assist you to preserve tasks organized by Python variations and packages wanted. For every Anaconda surroundings you arrange, you possibly can specify which model of Python to make use of and may preserve your entire associated programming information collectively inside that listing.

First, we will verify to see which variations of Python can be found for us to make use of:

You’ll obtain output with the totally different variations of Python which you can goal, together with each Python Three and Python 2 variations. Since we're utilizing the Anaconda with Python Three on this tutorial, you should have entry solely to the Python Three variations of packages.

Let’s create an surroundings utilizing the newest model of Python 3. We are able to obtain this by assigning model Three to the python argument. We’ll name the surroundings my_env, however you’ll seemingly wish to use a extra descriptive title to your surroundings particularly if you're utilizing environments to entry multiple model of Python.

  • conda create --name my_env python=3

We’ll obtain output with details about what's downloaded and which packages can be put in, after which be prompted to proceed with y or n. So long as you agree, kind y.

The conda utility will now fetch the packages for the surroundings and allow you to know when it’s full.

You possibly can activate your new surroundings by typing the next:

Together with your surroundings activated, your command immediate prefix will change:

Throughout the surroundings, you possibly can confirm that you simply’re utilizing the model of Python that you simply had supposed to make use of:

Output

Python 3.6.5 :: Anaconda, Inc.

Once you’re able to deactivate your Anaconda surroundings, you are able to do so by typing:

Observe which you can change the phrase supply with . to attain the identical outcomes.

To focus on a extra particular model of Python, you possibly can cross a selected model to the python argument, like 3.5, for instance:

  • conda create -n my_env35 python=3.5

You possibly can replace your model of Python alongside the identical department (as in updating Python 3.5.1 to Python 3.5.2) inside a respective surroundings with the next command:

If you want to focus on a extra particular model of Python, you possibly can cross that to the python argument, as in python=3.3.2.

You possibly can examine the entire environments you could have arrange with this command:

Output

# conda environments: # base * /residence/sammy/anaconda3 my_env /residence/sammy/anaconda3/envs/my_env my_env35 /residence/sammy/anaconda3/envs/my_env35

The asterisk signifies the present lively surroundings.

Every surroundings you create with conda create will include a number of default packages:

  • openssl
  • pip
  • python
  • readline
  • setuptools
  • sqlite
  • tk
  • wheel
  • xz
  • zlib

You possibly can add further packages, resembling numpy for instance, with the next command:

  • conda set up --name my_env35 numpy

If you prefer to a numpy surroundings upon creation, you possibly can goal it in your conda create command:

  • conda create --name my_env python=Three numpy

If you're now not engaged on a selected challenge and don't have any additional want for the related surroundings, you possibly can take away it. To take action, kind the next:

  • conda take away --name my_env35 --all

Now, once you kind the conda information --envs command, the surroundings that you simply eliminated will now not be listed.

Updating Anaconda

It is best to often make sure that Anaconda is up-to-date so that you're working with all the newest bundle releases.

To do that, it is best to first replace the conda utility:

When prompted to take action, kind y to proceed with the replace.

As soon as the replace of conda is full, you possibly can replace the Anaconda distribution:

Once more when prompted to take action, kind y to proceed.

This can guarantee that you're utilizing the newest releases of conda and Anaconda.

Uninstalling Anaconda

If you're now not utilizing Anaconda and discover that it's essential uninstall it, it is best to begin with the anaconda-clean module, which is able to take away configuration information for once you uninstall Anaconda.

  • conda set up anaconda-clean

Kind y when prompted to take action.

As soon as it's put in, you possibly can run the next command. You can be prompted to reply y earlier than deleting each. If you happen to would like to not be prompted, add --yes to the top of your command:

anaconda-clean

This will even create a backup folder referred to as .anaconda_backup in your house listing:

Output

Backup listing: /residence/sammy/.anaconda_backup/2018-05-23T213826

Now you can take away your whole Anaconda listing by getting into the next command:

Lastly, you possibly can take away the PATH line out of your .bashrc file that Anaconda added. To take action, first open a textual content editor resembling nano:

Then scroll all the way down to the top of the file (if this can be a latest set up) or kind CTRL + W to seek for Anaconda. Delete or remark out the export PATH line:

/residence/sammy/.bashrc

...
# added by Anaconda3 installer
export PATH="/home/sammy/anaconda3/bin:$PATH"

Once you’re carried out modifying the file, kind CTRL + X to exit and y to save lots of adjustments.

Anaconda is now eliminated out of your server.

Conclusion

This tutorial walked you thru the set up of Anaconda, working with the conda command-line utility, establishing environments, updating Anaconda, and deleting Anaconda if you happen to now not want it.

You need to use Anaconda that will help you handle workloads for knowledge science, scientific computing, analytics, and large-scale knowledge processing. From right here, you possibly can take a look at our tutorials on knowledge evaluation and machine studying to be taught extra about numerous instruments accessible to make use of and tasks that you are able to do.
