# Ubuntu/WSL2 Setup Guide

The following steps will help you set up the Zingg Development Environment on **Ubuntu/WSL2**.

### **Step 0: Initial OS Setup (Ubuntu/WSL2)**

Make sure to update your Ubuntu installation:

`sudo apt update`

**Step 0: Install Ubuntu on WSL2 on Windows**

* Install **wsl**: Type the following command in **Windows PowerShell**.

```
wsl --install
```

* Download Ubuntu from **Microsoft Store**, **Ubuntu 20.04 LTS**
* Configure Ubuntu with a **username** and **password**
* Open **Ubuntu 20.04 LTS** and start working

```
sudo apt update
```

* Follow this [tutorial](https://ubuntu.com/tutorials/install-ubuntu-on-wsl2-on-windows-10#1-overview) for more information.

**Step 1: Clone The Zingg Repository (Ubuntu)**

* Install and SetUp Git: **sudo apt install git**
* Verify : **git --version**
* Set up Git by following the [tutorial](https://www.digitalocean.com/community/tutorials/how-to-install-git-on-ubuntu-20-04).
* Clone the Zingg Repository: **git clone <https://github.com/zinggAI/zingg.git>**

**Note:** It is suggested to fork the repository to your account and then clone the repository.

**Step 2: Install JDK 11 (Ubuntu)**

* Follow this [tutorial](https://linuxize.com/post/install-java-on-ubuntu-20-04/) to install Java 11 JDK 11 in Ubuntu.
* For example:

```
sudo apt install openjdk-11-jdk openjdk-11-jre
javac -version
java -version
```

**Step 3: Install Apache Spark**

#### **Common Steps**

* Download Apache Spark - from the [Apache Spark Official Website](https://spark.apache.org/downloads.html).
* For example for 3.5.0:

```bash
curl -O https://archive.apache.org/dist/spark/spark-3.5.0/spark-3.5.0-bin-hadoop3.tgz
tar -xvf spark-3.5.0-bin-hadoop3.tgz
sudo mv spark-3.5.0-bin-hadoop3 /opt/spark
rm spark-3.5.0-bin-hadoop3.tgz
```

#### **Original Ubuntu Instructions (Manual Wget)**

* Install downloaded Apache Spark - on your Ubuntu by following [this tutorial](https://computingforgeeks.com/how-to-install-apache-spark-on-ubuntu-debian/).
* For example for 3.5.0:

```
wget https://www.apache.org/dyn/closer.lua/spark/spark-3.5.0/spark-3.5.0-bin-hadoop3.tgz
tar -xvf spark-3.5.0-bin-hadoop3.tgz
rm -rf spark-3.5.0-bin-hadoop3.tgz
sudo mv spark-3.5.0-bin-hadoop3 /opt/spark
```

Make sure that Spark version you have installed is compatible with Java you have installed, and Zingg is supporting those versions.

**Note**: Zingg supports Spark 3.5 and the corresponding Java version.

**Step 4: Install Apache Maven (Ubuntu)**

* Install the latest **maven** package.
* For example for 3.8.8:

```
wget https://dlcdn.apache.org/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz
tar -xvf apache-maven-3.8.8-bin.tar.gz 
rm -rf apache-maven-3.8.8-bin.tar.gz 
cd apache-maven-3.8.8/
cd bin
./mvn --version

Make sure that mvn -version should display correct java version as well(JAVA 11)
Apache Maven 3.8.7
Maven home: /usr/share/maven
Java version: 11.0.23, vendor: Ubuntu, runtime: /usr/lib/jvm/java-11-openjdk-amd64
```

**Step 5: Update Environment Variables (Ubuntu - \~/.bashrc)**

Open `.bashrc` and add env variables at the end of the file.

```
vim ~/.bashrc
export SPARK_HOME=/opt/spark
export SPARK_MASTER=local[*]
export MAVEN_HOME=/home/ubuntu/apache-maven-3.8.8
export ZINGG_HOME=<path_to_zingg>/assembly/target
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin:$JAVA_HOME/bin

```

\<path\_to\_zingg> will be a directory where you clone the repository of the Zingg. Similarly, if you have installed spark on a different directory you can set **SPARK\_HOME** accordingly.

**Note :-** Skip exporting MAVEN\_HOME if multiple maven version are not required

* Save/exit and do source .bashrc so that they reflect

```
source ~/.bashrc
```

* Verify:

```
echo $PATH
mvn --version

```

**Note:** If you have already set up **JAVA\_HOME** and **SPARK\_HOME** in the steps before you don't need to do this again.

**Step 6: Compile The Zingg Repository**

* Make sure you are executing the following commands in the same terminal window where you saved the bashrc. Run the following to compile the Zingg Repository -

```
git branch

```

* Run the following to Compile the Zingg Repository

```
mvn initialize
mvn clean compile package -Dspark=sparkVer
```

* Run the following to Compile while skipping tests

```
mvn initialize
mvn clean compile package -Dspark=sparkVer -Dmaven.test.skip=true
```

**Note:** Replace the `sparkVer` with the version of Spark you installed.\
For example, **-Dspark=3.5** you still face an error, include **-Dmaven.test.skip=true** with the above command.

**Step 7: If you have any issue with 'SPARK\_LOCAL\_IP' (Ubuntu)**

* Install **net-tools** using **sudo apt-get install -y net-tools**
* Run `ifconfig` in the terminal, find the **IP address** and paste the same in **/opt/hosts** IP address of your Pc-Name

**Step 8: Run Zingg To Find Training Data**

* Run this script in the terminal opened in Zingg clones directory `./scripts/zingg.sh --phase findTrainingData --conf examples/febrl/config.json`

**If everything is right, it should show Zingg banner.**

**Step 9: Run Zingg To label Data**

* Run this script in the terminal opened in Zingg clones directory `./scripts/zingg.sh --phase label --conf examples/febrl/config.json --properties-file config/zingg.conf`

**Step 10: Run Zingg To train model based on labelling**

* Run this script in the terminal opened in Zingg clones directory `./scripts/zingg.sh --phase train --conf examples/febrl/config.json --properties-file config/zingg.conf`

**Step 11: Run Zingg To prepare final output data**

* Run this script in the terminal opened in Zingg clones directory `./scripts/zingg.sh --phase match --conf examples/febrl/config.json --properties-file config/zingg.conf`
* change directory `cd /tmp/zinggOutput` (path provided in config file) to see the output files.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.zingg.ai/zingg/versions/enterprise-v0.8.0/contributing/settingupzingg/ubuntusetup.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
