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. Alternatively, you might choose to use a package manager such as Conda to install and maintain packages and their dependencies. For some basic usage guidelines for Conda, see the Conda website.
(Python and R) Install Packages Using Workbench Command Prompt
- Navigate to your project's Overview page. Click Open Workbench and launch a session.
- 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.packages("ggplot2") # Install using devtools install.packages('devtools') library(devtools) install_github("hadley/ggplot2")
# Installing from console using ! shell operator and pip: !pip install beautifulsoup # Installing from terminal pip install beautifulsoup
# 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
requirements.txt file that lives in your project.
The packages can be installed all at once using pip/pip3.
- Create a new file called
requirements.txtfile within your project:
- To install the packages in a Python 3 engine, run the following
command in the workbench command prompt.
!pip3 install -r requirements.txtFor Python 2 engines, use
!pip install -r requirements.txt
