Conda Environment task
Use this task in a build or release pipeline to create and activate a Conda environment.
This task will create a Conda environment and activate it for subsequent build tasks.
If the task finds an existing environment with the same name, the task will simply reactivate it. This is possible on self-hosted agents. To recreate the environment and reinstall any of its packages, set the "Clean the environment" option.
Running with the "Update to the latest Conda" option will attempt to update Conda before creating or activating the environment. If you are running a self-hosted agent and have configured a Conda installation to work with the task, this may result in your Conda installation being updated.
Microsoft-hosted agents won't have Conda in their
PATH by default. You will need to run this task in order to use Conda.
After running this task,
PATH will contain the binary directory for the activated environment, followed by the binary directories for the Conda installation itself.
You can run scripts as subsequent build tasks that run Python, Conda, or the command-line utilities from other packages you install.
For example, you can run tests with pytest or upload a package to Anaconda Cloud with the Anaconda client.
After running this task, the environment will be "activated," and packages you install by calling
conda install will get installed to this environment.
- A Microsoft-hosted agent, or a self-hosted agent with Anaconda or Miniconda installed.
- If using a self-hosted agent, you must either add the
PATHor set the
CONDAenvironment variable to the root of the Conda installation.

Q & A
Do I need an agent?
You need at least one agent to run your build or release. Get an agent for Linux, macOS, or Windows.
I'm having problems. How can I troubleshoot them?
I can't select a default agent pool and I can't queue my build or release. How do I fix this?
See Agent pools.
How can I configure a self-hosted agent to use this task?
You can use this task either with a full Anaconda installation or a Miniconda installation.
If using a self-hosted agent, you must add the
conda executable to
Alternatively, you can set the
CONDA environment variable to the root of the Conda installation -- that is, the directory you specify as the "prefix" when installing Conda.
