Libraries

Third-Party Libraries

Introduction

The Lean CLI supports using dozens of open source packages in your algorithms. These packages are reviewed by our security team, and when approved, can be used in backtesting, live trading, and research. To use these packages in your algorithm, you will need to add the relevant usingimport statement at the top of your code file.

By default, only the libraries in the official LEAN Docker images can be referenced in your algorithms. However, the CLI also supports using custom libraries. This makes it possible to use a library that is not available in the official LEAN Docker images or to use a newer version of an existing library.

Supported Libraries for AMD64 Systems

The CLI supports many of the most popular C# and Python open-source libraries. On AMD64-based systems, the CLI supports the same C# and Python libraries as are supported on QuantConnect. If you're unsure about the architecture of your system, it's most likely AMD64. The following libraries are available on AMD64-based systems:

Request New Libraries

To request a new library, contact us. We will add the library to the queue for review and deployment. Since the libraries run on our servers, we need to ensure they are secure and won't cause harm. The process of adding new libraries takes 2-4 weeks to complete. View the list of libraries currently under review on the Issues list of the Lean GitHub repository.

Add Libraries

Follow these steps to add custom libraries to your C#Python project:

  1. Find the name of the package that you want to add on NuGet.
  2. Open a terminal in the organization workspace that stores the project.
  3. Run lean library add "<projectName>" <packageName> to add the <packageName> NuGet package to the project in . / <projectName>.
    $ lean library add "My Project" Microsoft.ML
Retrieving latest available version from NuGet
Adding Microsoft.ML 1.5.5 to 'My Project/My Project.csproj'
Restoring packages in 'My Project' to provide local autocomplete
    This command installs the latest version of the Microsoft.ML package. If you want to use a different version you can use the --version <value> option. Additionally, you can pass the --no-local flag to skip restoring the packages locally.
  1. Find the name of the package that you want to add on PyPI.
  2. Open a terminal in the organization workspace that stores the project.
  3. Run lean library add "<projectName>" <packageName> to add the <packageName> PyPI package to the project in . / <projectName>.
    $ lean library add "My Project" altair
Retrieving latest compatible version from PyPI
Adding altair 4.1.0 to 'My Project/requirements.txt'
Installing altair 4.1.0 in local Python environment to provide local autocomplete
    This command installs the latest version of the altair package that is compatible with Python 3.11 (which is what the official LEAN Docker images use). If you want to use a different version you can use the --version <value> option. Additionally, you can pass the --no-local flag to skip installing the package in your local Python environment.
  4. If you are using VS Code, restart your editor for autocomplete to start working on the new library.

Additionally, you can also add custom C# libraries by modifying the C# project file (the file ending with .csproj). This can be done manually or through your editor's built-in NuGet tooling if your editor has such a feature.

Additionally, you can also add custom Python libraries by modifying the project's requirements.txt file. If you choose to do this, make sure that the library versions that you add to this file are compatible with Python 3.6, because that's what the official LEAN Docker images use.

Remove Libraries

Follow these steps to remove custom libraries from your C#Python project:

  1. Open a terminal in the organization workspace that stores the project.
  2. Run lean library remove "<projectName>" <packageName> to remove the <packageName> NuGet package from the project in . / <projectName>.
    $ lean library remove "My Project" Microsoft.ML
Removing Microsoft.ML from 'My Project/My Project.csproj'
Restoring packages in 'My Project'
    You can pass the --no-local flag to skip restoring the packages locally.
  1. Open a terminal in the organization workspace that stores the project.
  2. Run lean library remove "<projectName>" <packageName> to remove the <packageName> PyPI package from the project in . / <projectName>.
    $ lean library remove "My Project" altair
Removing altair from 'My Project/requirements.txt'

Additionally, you can also remove custom C# libraries by modifying the C# project file (the file ending with .csproj). This can be done manually or through your editor's built-in NuGet tooling if your editor has such a feature.

Additionally, you can also remove custom Python libraries by modifying the project's requirements.txt file.
