# Installation This section describes how to install the onetick-py package to use remotely with OneTick REST API, such as used by [OneTick Cloud](https://www.onetick.com/cloud-services). In this case, the package does not require OneTick binaries to be installed on the client side. - If you have OneTick binaries installed on your machine and want to use onetick-py locally with them, please refer to the [On-Premises Installation](onprem.md#onprem-installation) section. - If you want to configure your on-premise OneTick server with WebAPI support, see [WebAPI with on-prem OneTick server](webapi_onprem.md#webapi-onprem-installation). - If you need to install onetick-py from OneTick's pip-servers or install onetick-py without internet connection, see [Other installation options](pip.md#pip-installation). ## Prerequisites - You installed [python 3.9 or newer](https://www.python.org/downloads/). - You installed [pip](https://pip.pypa.io/en/stable/installing/). - Optional, but it is **highly recommended** to use virtual environment for Python packages. > Create and activate it with following commands: > - Linux / MacOS: `python3 -m venv venv && source venv/bin/activate` > - Windows (cmd): `python -m venv venv && venv\Scripts\activate` ## Installation from PyPI The latest version of onetick-py is available on PyPI: [https://pypi.org/project/onetick-py/](https://pypi.org/project/onetick-py/). ```default pip install onetick-py[webapi] ``` `webapi` extra is needed to install additional dependencies required for REST connectivity to the OneTick server, over either HTTP or HTTPS using Arrow as a transport format. ## Getting started Go to the [Getting Started](../getting_started/root.md#getting-started) page.
