Uploading and Downloading a Conda Package via the Client

Conda Package

Conda is an open-source package manager and environment management system widely used in scientific computing, data science, and machine learning. It supports Windows, macOS, and Linux, and manages packages for Python and other languages such as R, Java, and C++. Conda artifacts are packages published via Conda.

Constraints

The repository password for a self-hosted repo is account-specific. If you are prompted for a password while using a different account, download the configuration file from the repository's Tutorial tab to obtain it.

Prerequisites

• You have installed the Conda client.
• You have created a Conda repository.
• You have the Download/View permission on the current repository. For details about how to obtain this permission, see Configuring Repository Permissions.
