Under the hood
Default runtime environments
For each language, Datagrok uses a predefined header and creates an environment with the set of pre-installed packages.
- Python
- R
- Octave
- Julia
- JavaScript
import os
import io
import json
import pandas as pd
import requests
from datetime import datetime, timedelta
require(httr)
require(repr)
require(data.table)
require(R.utils)
Octave scripts run in a separate container on server. This container has following Octave packages pre-installed:
Always provide pkg load %PACKAGE_NAME% in your scripts, since script runs are fully independent.
using HTTP
using DataFrames
using CSV
using Compat
using MbedTLS
using Dates
using JSON

Environment isolation
You can specify an environment for the script to use, including the language version and a set of libraries.
Datagrok uses Conda as the environment management system. A Conda environment:
- isolates each script run,
- resolves dependencies,
- and takes time to be created before a script run.
Later, the script uses the pre-created environment with no delay for resolving dependencies.
In Datagrok, Conda environment configuration can be specified either right inside the script or as part of a package.
