Installation

Linux systems must meet the following minimum requirements to run Local Platform:

• 4 GB RAM or more
• 60 GB hard drive or more

You need an internet connection for things like downloading updates, collaborating with team members, and syncing your projects with QuantConnect Cloud. Trading Firm and Institution organizations can run local backtests and research notebooks without an internet connection for up to 24 hours.

If you run the LEAN engine locally with QuantConnect Local Platform, LEAN executes in a Docker container. These Docker containers contain a minimal Linux-based operating system, the LEAN engine, and all the packages available to you on QuantConnect.com. It is therefore required to install Docker if you plan on using QuantConnect Local Platform to run the LEAN engine locally.

To install, see Install Docker Desktop on Linux in the Docker documentation.

Follow these steps to install Local Platform:

1. Install Docker.
2. Open a terminal and download the latest LEAN image.

$ docker pull quantconnect/lean

It takes about an hour to download the image. While it's downloading, continue to the next step. When you use Local Platform, it automatically pulls the latest LEAN image if your current version is more than a week old.

3. Install Visual Studio Code.
4. Install Local Platform.

If you open Visual Studio Code and it asks you to log in to QuantConnect, you successfully installed Local Platform.

Log in to your account and then set up your first organization workspace.

After you install Local Platform, follow these steps:

1. Log in to your account.
2. Set up your first organization workspace.
3. Install the Python stubs for autocomplete.

The following sections explain how to solve some issues you may encounter while installing Local Platform.

Docker Not Found

If you have Docker installed but the Local Platform can't detect it, update your Executable Path: Docker setting to be the path to your Docker executable.

LEAN CLI Account Syncronization

Local Platform and the LEAN CLI share your login credentials. If you log in to your account on Local Platform or the LEAN CLI, you log into that account for both Local Platform and the LEAN CLI.
