What is the correct combo for Anaconda and Cylc on RHEL 8

Cylc Cylc Support
1

I have installed Anaconda and tried to use:

conda install -c conda-forge cylc-flow

It runs for a long time, and then exits. What combination of Anaconda and Cylc run on RHEL 8?

You need to use the much faster mamba environment solver, with conda.

The conda command can now use the superior Mamba algorithm if installed - Anaconda | A Faster Solver for Conda: Libmamba

The same thing happened with Mamba, as it didn’t with Conda:

It looks as if you’re trying to install Cylc into a massive central conda environment? That (IMO at least) is appropriate for Python libraries used by many developers on the system. But for a large and complex application(s) like Cylc, it greatly increases the odds on running into horrible environment conflicts.

You should install Cylc into a dedicated virtual environment.

Yes, we recommend installing Cylc into its own environment. Installing lots of utilities into the same environment will likely result in conflicts like this.

Cylc is a system utility so it’s more natural to install it into a standalone environment where it can be upgraded independently of other systems. This pattern also supports parallel deployment of multiple Cylc versions via a wrapper script which also removes the requirement for manual environment activation.

There is no advantage to installing Cylc into a larger scientific environment because Cylc tasks are run outside of the Cylc environment itself so cannot benefit from other libraries in the environment.
