This article covers the step-by-step instructions for installing the Azure ML SDK for R.
You do not need run this if you are working on an Azure Machine Learning Compute Instance, as the compute instance already has the Azure ML SDK preinstalled.
If you do not have Conda already installed on your machine, you will first need to install it, since the Azure ML R SDK uses reticulate to bind to the Python SDK. We recommend installing Miniconda, which is a smaller, lightweight version of Anaconda. Choose the 64-bit binary for Python 3.5 or later.
The stable release of the Azure ML SDK can be installed from CRAN or the development version can be installed from GitHub. You will need remotes to install the azuremlsdk package.
Then, you can use the
install_cran functions to install the package.
If you are using R installed from CRAN, which comes with 32-bit and 64-bit binaries, you may need to specify the parameter
INSTALL_opts=c("--no-multiarch") to only build for the current 64-bit architecture.
Lastly, use the azuremlsdk R library to install the latest version of the Python SDK.
install_azureml() creates a conda environment called ‘r-reticulate’, installs the Python SDK in that environment, and restarts the R session after installation (if running in RStudio). If you would like to override the default version of the Python SDK, the environment name, or the Python version, you can pass in those arguments. If you would like to delete the conda environment if it already exists and create a new environment, or not restart the R session after installation, you can also do so:
You can confirm your installation worked by loading the library and successfully retrieving a run.
If you’re using the compute instance, the first time you run
library(azuremlsdk) you may run into the following prompt:
This is the reticulate package prompting the user if they want to have Miniconda installed (see GitHub issue). Since the compute instance already has Anaconda, you can just respond “N” to the prompt. You will receive the message “Installation aborted”, which just means that Miniconda won’t be installed. You will only be prompted for this once for each new compute instance you spin up.
In step 3 of the installation, if you get ssl errors on windows, it is due to an outdated openssl binary. Install the latest openssl binaries from here.
If installation fails due to this error:
You will need to set your time zone environment variable to GMT and restart the installation process.
If the following permission error occurs while installing in RStudio, change your RStudio session to administrator mode, and re-run the installation command.
