I am having trouble installing Orange.

Make sure you are downloading the latest version. You can also try to download a standalone installer or Anaconda distribution.

Still no luck? Check our issue tracker for similar issues or report a new one.

I am having trouble installing an add-on.

Make sure you are using the latest version of Orange. Encountering issues, please raise them on the relevant add-on's issue tracker. Alternatively, you can try with Anaconda distribution and install the add-on in the terminal. You can use pip or conda to install a package directly. E.g.:

pip install orange3-text

conda install orange3-timeseries

I get an error when using Orange.

Please use this option as it allows us to recreate the issue and fix it. If this is not possible, please report the issue to our issue tracker.

I would like to learn how to use Orange. Where can I find the resources?

Widget documentation is available on our website. You can also access the same documentation directly from Orange by selecting the widget and pressing F1.

We also provide an e-mail course ( subscribe here), beginner-level YouTube tutorials and a regularly updated blog.

I have a question concerning data mining, statistics and machine learning algorithms.

What data does Orange support?

Core Orange supports Excel, comma- and tab-delimited files (.xlsx, .csv, .tab). It also reads online data, such as Google Spreadsheets. Orange3-ImageAnalytics add-on can import images (.jpg, .tiff, .png). Orange3-Corpus add-on can import text files (.txt, .docx, .odt). SQL widget supports PostgreSQL and MSSQL databases.

I want to use Orange on big data.

Orange provides the SQL widget, which samples data instances and enables exploratory data analysis on large datasets. You need psycopg2 module installed to be able to see the widget. Install it directly in Python with

pip install psycopg2

command. You can also use 2UDA package for easier installation. Please note that Orange supports only PostgreSQL and MSSQL databases for now.

Can I export Orange workflow as a Python script?

Unfortunately, no. We’ve debated this long and hard. A (limited) functionality of this type would probably be possible, but would be a very big project to do well and would cost more than the expected benefits.

I wish to propose a collaboration and/or a project with the Orange team.

Please submit a contact request and we will respond as soon as we can.

I wish to develop a widget / an add-on for Orange.

We are always happy to receive contributions! Development documentation for widgets and add-ons is available on the web. Next, submit a pull request and our team will review it. If you have specific questions, use Gitter for direct communication with the developers.

I wish to commission a custom module and/or an add-on for Orange.

Please submit a contact request to discuss the idea and rates.
