What’s new 2022.1 (March)

Datalore Enterprise 2022.1 introduces Reactive mode for Interactive reports, new controls, CSV file previews and editing, out-of-the-box descriptive statistics for DataFrames, and more.
Read on for the highlights of this release!

DataFrame statistics

With one click, you can get essential descriptive statistics for a DataFrame inside a separate Statistics tab. For categorical columns, you will see the distribution of values, and for numerical columns, Datalore will calculate the min, max, median, standard deviation, percentiles, and also highlight the percentage of zeros and outliers.

CSV file previews

Open CSV and TSV files from the Attached data tab in a separate tab inside Datalore’s editor. Sort the column values and paginate the file contents.

CSV file editing

Create and edit CSV and TSV files right inside the Datalore editor. You can start from scratch and create a new file or you can edit the contents of an existing one.

New interactive controls

We added new interactive controls to the Datalore notebooks, and now you can add:

  • Checkboxes that will assign a certain variable with either a True or False value.
  • A multi-select option for dropdowns.
  • A textarea for longer text inputs.
  • Visibility control that will collapse the specified number of subsequent cells in the reports.
  • Upper and lower limits can be defined from variables in the Slider controls.

Reactive mode for reports

You can use Reactive mode in your Interactive reports to update the report contents when users change something. Without Reactive mode, users will need to click the Recompute button each time to update the results.

Full width mode for reports

You can turn on full width mode to use the entire width of the browser window to display outputs including graphics and charts.

Сut-off timer for background computation

Background computation mode in Datalore allows you to run computations even if the browser tab is closed. In this release, we’ve added the ability to set when the notebook computation will shut down after the kernel goes idle. If you are training your models on expensive-to-run machines, this feature will help you reduce computation costs. To help you check whether Background computation is switched on, we’ve also added an indicator to the bottom-right corner of the editor.

Tracking collaborator’s cursor

You can navigate to a collaborator's cursor and follow along in real time simply by clicking on the collaborator’s account icon in the upper-right corner.

Object size inside Variable viewer

The Variable viewer allows you to see the full list of variable values defined in the notebook, including user-created variables and everything that is built into the function. You can also see the size of objects inside the Variable viewer tab.

User actions log

You can turn on user action logging inside your on-premises setups. The logs will help you investigate any compliance requests.

Other improvements:

  • Worksheets can be duplicated in the notebook.
  • The viewport will extend when the last cell of the notebook is scrolled past.
  • Cells that are queued for processing are indicated better.
  • Empty code cells are now automatically hidden in the reports.
