Synapse Machine Learning

SynapseML (previously MMLSpark) is an open source library to simplify the creation of scalable machine learning pipelines. SynapseML builds on Apache Spark and SparkML to enable new kinds of machine learning, analytics, and model deployment workflows. SynapseML adds many deep learning and data science tools to the Spark ecosystem, including seamless integration of Spark Machine Learning pipelines with the Open Neural Network Exchange (ONNX), LightGBM, The Cognitive Services, Vowpal Wabbit, and OpenCV. These tools enable powerful and highly-scalable predictive and analytical models for a variety of datasources.

SynapseML also brings new networking capabilities to the Spark Ecosystem. With the HTTP on Spark project, users can embed any web service into their SparkML models. For production grade deployment, the Spark Serving project enables high throughput, sub-millisecond latency web services, backed by your Spark cluster.

SynapseML requires Scala 2.12, Spark 3.2+, and Python 3.6+. See the API documentation for Scala and for PySpark.

Setup and installation

First select the correct platform that you are installing SynapseML into:

Synapse Analytics
Databricks
Python Standalone
Spark Submit
SBT
Apachy Livy and HDInsight
Docker
R (Beta)
Building from Source

Synapse Analytics

In Azure Synapse notebooks please place the following in the first cell of your notebook.

For Spark 3.2 Pools:

%%configure -f
{
  "name": "synapseml",
  "conf": {
      "spark.jars.packages": "com.microsoft.azure:synapseml_2.12:0.9.5",
      "spark.jars.repositories": "https://mmlspark.azureedge.net/maven",
      "spark.jars.excludes": "org.scala-lang:scala-reflect,org.apache.spark:spark-tags_2.12,org.scalactic:scalactic_2.12,org.scalatest:scalatest_2.12",
      "spark.yarn.user.classpath.first": "true"
  }
}

For Spark 3.1 Pools:

%%configure -f
{
  "name": "synapseml",
  "conf": {
      "spark.jars.packages": "com.microsoft.azure:synapseml_2.12:0.9.5-13-d1b51517-SNAPSHOT",
      "spark.jars.repositories": "https://mmlspark.azureedge.net/maven",
      "spark.jars.excludes": "org.scala-lang:scala-reflect,org.apache.spark:spark-tags_2.12,org.scalactic:scalactic_2.12,org.scalatest:scalatest_2.12",
      "spark.yarn.user.classpath.first": "true"
  }
}

To install at the pool level instead of the notebook level add the spark properties listed above to the pool configuration.

Databricks

To install SynapseML on the Databricks cloud, create a new library from Maven coordinates in your workspace.

For the coordinates use: com.microsoft.azure:synapseml_2.12:0.9.5 with the resolver: https://mmlspark.azureedge.net/maven. Ensure this library is attached to your target cluster(s).

Finally, ensure that your Spark cluster has at least Spark 3.2 and Scala 2.12. If you encounter Netty dependency issues please use DBR 10.1.

You can use SynapseML in both your Scala and PySpark notebooks. To get started with our example notebooks import the following databricks archive:

https://mmlspark.blob.core.windows.net/dbcs/SynapseMLExamplesv0.9.5.dbc

Python Standalone

To try out SynapseML on a Python (or Conda) installation you can get Spark installed via pip with pip install pyspark. You can then use pyspark as in the above example, or from python:

import pyspark
spark = pyspark.sql.SparkSession.builder.appName("MyApp") \
            .config("spark.jars.packages", "com.microsoft.azure:synapseml_2.12:0.9.5") \
            .getOrCreate()
import synapse.ml

Spark Submit

SynapseML can be conveniently installed on existing Spark clusters via the --packages option, examples:

spark-shell --packages com.microsoft.azure:synapseml_2.12:0.9.5
pyspark --packages com.microsoft.azure:synapseml_2.12:0.9.5
spark-submit --packages com.microsoft.azure:synapseml_2.12:0.9.5 MyApp.jar

SBT

If you are building a Spark application in Scala, add the following lines to your build.sbt:

libraryDependencies += "com.microsoft.azure" % "synapseml_2.12" % "0.9.5"

Apache Livy and HDInsight

To install SynapseML from within a Jupyter notebook served by Apache Livy the following configure magic can be used. You will need to start a new session after this configure cell is executed.

Excluding certain packages from the library may be necessary due to current issues with Livy 0.5.

%%configure -f
{
    "name": "synapseml",
    "conf": {
        "spark.jars.packages": "com.microsoft.azure:synapseml_2.12:0.9.5",
        "spark.jars.excludes": "org.scala-lang:scala-reflect,org.apache.spark:spark-tags_2.12,org.scalactic:scalactic_2.12,org.scalatest:scalatest_2.12"
    }
}

Docker

The easiest way to evaluate SynapseML is via our pre-built Docker container. To do so, run the following command:

docker run -it -p 8888:8888 -e ACCEPT_EULA=yes mcr.microsoft.com/mmlspark/release

Navigate to http://localhost:8888/ in your web browser to run the sample notebooks. See the documentation for more on Docker use.

To read the EULA for using the docker image, run \ docker run -it -p 8888:8888 mcr.microsoft.com/mmlspark/release eula

R (Beta)

To try out SynapseML using the R autogenerated wrappers see our instructions. Note: This feature is still under development and some necessary custom wrappers may be missing.

Building from source

SynapseML has recently transitioned to a new build infrastructure. For detailed developer docs please see the Developer Readme

If you are an existing synapsemldeveloper, you will need to reconfigure your development setup. We now support platform independent development and better integrate with intellij and SBT. If you encounter issues please reach out to our support email!
