# Synapse Machine Learning



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](https://spark.apache.org/) and shares the same API as the [SparkML/MLLib library](https://spark.apache.org/mllib/), 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+.

## Documentation and Examples



For quickstarts, documentation, demos, and examples please see our [website](https://aka.ms/spark).



## Setup and installation



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



- [Microsoft Fabric](#microsoft-fabric)

- [Synapse Analytics](#synapse-analytics)

- [Databricks](#databricks)

- [Python Standalone](#python-standalone)

- [Spark Submit](#spark-submit)

- [SBT](#sbt)

- [Apache Livy and HDInsight](#apache-livy-and-hdinsight)

- [Docker](#docker)

- [R](#r)

- [Building from source](#building-from-source)



### Microsoft Fabric



In Microsoft Fabric notebooks SynapseML is already installed. To change the version please place the following in the first cell of your notebook.



```bash

%%configure -f

{

  "name": "synapseml",

  "conf": {

      "spark.jars.packages": "com.microsoft.azure:synapseml_2.12:",

      "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"

  }

}

```



### Synapse Analytics



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



- For Spark 3.4 Pools:



```bash

%%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:



```bash

%%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](https://techcommunity.microsoft.com/t5/azure-synapse-analytics-blog/how-to-set-spark-pyspark-custom-configs-in-synapse-workspace/ba-p/2114434).



### Databricks



To install SynapseML on the [Databricks

cloud](http://community.cloud.databricks.com), create a new [library from Maven

coordinates](https://docs.databricks.com/user-guide/libraries.html#libraries-from-maven-pypi-or-spark-packages)

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`



### 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:



```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.ml

```



### Spark Submit



SynapseML can be conveniently installed on existing Spark clusters via the

`--packages` option, examples:



```bash

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.jar

```



### SBT



If you are building a Spark application in Scala, add the following lines to

your `build.sbt`:



```scala

libraryDependencies += "com.microsoft.azure" % "synapseml_2.12" % "1.0.4"

```



### 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.



```bash

%%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"

    }

}

```



### Docker



The easiest way to evaluate SynapseML is via our pre-built Docker container.  To

do so, run the following command:



```bash

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

```



Navigate to  in your web browser to run the sample

notebooks.  See the [documentation](https://microsoft.github.io/SynapseML/docs/Reference/Docker%20Setup/) 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



To try out SynapseML using the R autogenerated wrappers [see our

instructions](https://microsoft.github.io/SynapseML/docs/Reference/R%20Setup/).  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](https://microsoft.github.io/SynapseML/docs/Reference/Developer%20Setup/)



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!
