Install DQO using PIP


To use DQO you need:

  • Python version 3.8 or greater (for details see Python's documentation and download sites).

    To confirm that you have Python installed run the following command

    python --version
    To view the Python 3 version, run python3 --version instead.

  • Ability to install Python packages with pip.

    To confirm that you have pip installed run the following command

    pip --version
    Current version of pip should be displayed.

  • Installed JDK software (version 17) and set the JAVA_HOME environment variable.

    To confirm that Java is installed on your system, please run this command:

    java --version
    A Java version should be displayed. If the above command shows 'java' is not recognized, it means Java is not installed or the path is not properly set.

    To ensure that the JAVA_HOME environmental variables are properly set, please run the following command:

    echo %JAVA_HOME%


DQO is available on PyPi repository.

  1. Create an empty catalogue where you want to install DQO.
  2. Open a terminal, navigate to the created directory, and install DQO via pip manager

    python -m pip install --user dqops

Start DQO application

  1. Run dqo app to finalize the installation. This process may take some time as the DQO distribution will be downloaded and the Python environment will be initialized in the DQO home directory.

    python -m dqops
  2. Create DQO userhome folder.

    After installation, you will be asked whether to initialize the DQO userhome folder in the default location. Type Y to create the folder.
    The userhome folder locally stores data such as sensor readouts and checkout results, as well as data source configurations. You can learn more about data storage here.

  3. Login to DQO Cloud.

    To use DQO features, such as storing data quality definitions and results in the cloud or data quality dashboards, you must create a DQO cloud account.

    After creating a userhome folder, you will be asked whether to log in to the DQO cloud. After typing Y, you will be redirected to, where you can create a new account, use Google single sign-on (SSO) or log in if you already have an account.

    During the first registration, a unique identification code (API Key) will be generated and automatically retrieved by DQO application. The API Key is now stored in the configuration file.

  4. Open the DQO User Interface Console in your browser by CTRL-clicking on the link displayed on the command line (for example http://localhost:8888) or by copying the link.
