Installing Additional Packages

Cloudera Machine Learning engines are preloaded with a few common packages and libraries for R, Python, and Scala. However, a key feature of Cloudera Machine Learning is the ability of different projects to install and use libraries pinned to specific versions, just as you would on your local computer.

Generally, Cloudera recommends you install all required packages locally into your project. This will ensure you have the exact versions you want and that these libraries will not be upgraded when Cloudera upgrades the base engine image. You only need to install libraries and packages once per project. From then on, they are available to any new engine you spawn throughout the lifetime of the project.

You can install additional libraries and packages from the workbench, using either the command prompt or the terminal.

(Python and R) Install Packages Using Workbench Command Prompt

To install a package from the command prompt:
  1. Navigate to your project's Overview page. Click Open Workbench and launch a session.
  2. At the command prompt (see Native Workbench Console and Editor) in the bottom right, enter the command to install the package. Some examples using Python and R have been provided.


# Install from CRAN 

# Install using devtools 

Python 2

# Installing from console using ! shell operator and pip:
!pip install beautifulsoup

# Installing from terminal
pip install beautifulsoup

Python 3

# Installing from console using ! shell operator and pip3:
!pip3 install beautifulsoup4

# Installing from terminal
pip3 install beautifulsoup4

(Python Only) Using a Requirements File

For a Python project, you can specify a list of the packages you want in a requirements.txt file that lives in your project. The packages can be installed all at once using pip/pip3.

  1. Create a new file called requirements.txt file within your project:
  2. To install the packages in a Python 3 engine, run the following command in the workbench command prompt.
    !pip3 install -r requirements.txt
    For Python 2 engines, use pip.
    !pip install -r requirements.txt
