SynapseML (previously known as MMLSpark), is an open-source library that simplifies the creation of massively scalable machine learning (ML) pipelines. SynapseML provides simple, composable, and distributed APIs for a wide variety of different machine learning tasks such as text analytics, vision, anomaly detection, and many others. SynapseML is built on the Apache Spark distributed computing framework and shares the same API as the SparkML/MLLib library, allowing you to seamlessly embed SynapseML models into existing Apache Spark workflows.
With SynapseML, you can build scalable and intelligent systems to solve challenges in domains such as anomaly detection, computer vision, deep learning, text analytics, and others. SynapseML can train and evaluate models on single-node, multi-node, and elastically resizable clusters of computers. This lets you scale your work without wasting resources. SynapseML is usable across Python, R, Scala, Java, and .NET. Furthermore, its API abstracts over a wide variety of databases, file systems, and cloud data stores to simplify experiments no matter where data is located.
SynapseML requires Scala 2.12, Spark 3.4+, and Python 3.8+.

For quickstarts, documentation, demos, and examples please see our website.
First select the correct platform that you are installing SynapseML into:
- Microsoft Fabric
- Synapse Analytics
- Databricks
- Python Standalone
- Spark Submit
- SBT
- Apache Livy and HDInsight
- Docker
- R
- Building from source
In Microsoft Fabric notebooks SynapseML is already installed. To change the version please place the following in the first cell of your notebook.
%%configure -f
{
"name": "synapseml",
"conf": {
"spark.jars.packages": "com.microsoft.azure:synapseml_2.12:<THE_SYNAPSEML_VERSION_YOU_WANT>",
"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,com.fasterxml.jackson.core:jackson-databind",
"spark.yarn.user.classpath.first": "true",
"spark.sql.parquet.enableVectorizedReader": "false"
}
}In Azure Synapse notebooks please place the following in the first cell of your notebook.
- For Spark 3.4 Pools:
%%configure -f
{
"name": "synapseml",
"conf": {
"spark.jars.packages": "com.microsoft.azure:synapseml_2.12:1.0.4",
"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,com.fasterxml.jackson.core:jackson-databind",
"spark.yarn.user.classpath.first": "true",
"spark.sql.parquet.enableVectorizedReader": "false"
}
}- For Spark 3.3 Pools:
%%configure -f
{
"name": "synapseml",
"conf": {
"spark.jars.packages": "com.microsoft.azure:synapseml_2.12:0.11.4-spark3.3",
"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,com.fasterxml.jackson.core:jackson-databind",
"spark.yarn.user.classpath.first": "true",
"spark.sql.parquet.enableVectorizedReader": "false"
}
}To install at the pool level instead of the notebook level add the spark properties listed above to the pool configuration.
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_2.12:1.0.4
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/SynapseMLExamplesv1.0.4.dbc
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_2.12:1.0.4") \
.getOrCreate()
import synapse.mlSynapseML can be conveniently installed on existing Spark clusters via the
--packages option, examples:
spark-shell --packages com.microsoft.azure:synapseml_2.12:1.0.4
pyspark --packages com.microsoft.azure:synapseml_2.12:1.0.4
spark-submit --packages com.microsoft.azure:synapseml_2.12:1.0.4 MyApp.jarIf you are building a Spark application in Scala, add the following lines to
your build.sbt:
libraryDependencies += "com.microsoft.azure" % "synapseml_2.12" % "1.0.4"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_2.12:1.0.4",
"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,com.fasterxml.jackson.core:jackson-databind"
}
}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 jupyter notebookNavigate 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
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.
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!
