Conda / Anaconda
Conda / Anaconda (https://conda.org) is a package manager that can be used to easily create tailored Python environments without having required C/... binaries of some packages installed on the local system. (i.e. conda will take care that required binaries are installed into the environment)
Due to certain license restrictions the usage of Anaconda at PSI is not allowed without obtaining a professional license from Anaconda.com!
However the usage of the command `conda` and/or of packages from conda-forge is still possible - see below ...
This guide explains how to install and configure conda in accordance to the Anaconda.com license terms.
Installation
On a standard Linux system the conda package can be simply installed via a:
yum install conda
To instruct puppet to install the package you can have following hiera config:
base::pkg_group::extra:
- 'conda'
base::package_groups:
- 'extra'
Configuration
To overwrite the default configuration of conda (which would violate the license because packages would be installed from anaconda.org by default) following config file needs to be deployed in /etc/conda/condarc.d/base.yml (or similar):
channels:
- conda-forge
# Show channel URLs when displaying what is going to be downloaded
# and in 'conda list'. The default is False.
show_channel_urls: True
always_copy: true
To place the file via Puppet/Hiera you can have following configuration:
files::files:
/etc/conda/condarc.d/base.yml:
content: |
channels:
- conda-forge
# Show channel URLs when displaying what is going to be downloaded
# and in 'conda list'. The default is False.
show_channel_urls: True
always_copy: true
Afterwards conda environments can be created in a license conformed way as documented at https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html
