Problems installing the package

[plcrodrigues]

Hi, everyone. After reading the "Calibrate, Emulate, Sample" paper by Cleary et al. I wanted to play a bit with the algorithms and get a better grasp of the full methodology. I was, therefore, vey happy to see that the paper came with a well structured documentation. Kudos for that! Unfortunately, I was unable to install the package on a newly created environment on my MacBook Air with ARM architecture.

The error that I get after doing

julia --project
> ]
> add Conda
> add CalibrateEmulateSample

is the following

PkgPrecompileError: The following 1 direct dependency failed to precompile:

CalibrateEmulateSample [95e48a1f-0bec-4818-9538-3db4340308e3]

Am I missing something? (disclaimer: I have near to zero experience with Julia language...)

Thanks for your attention!

Ah, I guess it must be connected to this : CliMA/EnsembleKalmanProcesses.jl@dab5aff

I installed version 1.1.5 of EnsembleKalmanProcesses and it worked fine.

Apologies! Just working on this one - Yeah we overhauled the Observations. I messed up doing an EKP release of v1.1.X where I should have done v1.2.1. This would prevent CES automatically updating to a breaking change!

[odunbar]

If you could please fix your version to v1.1.5 for now and this should be resolved ASAP! Thanks for reporting this. As the EKP change was last night, and I am working on the CES compat today - I am afraid you hit the perfect storm.

[plcrodrigues]

No problem, it forced me to try to understand a bit more of Julia and its inner workings :)

[odunbar]

OK the fix is in!
Currently this is just on main, so

• if you are installing CES locally you can use git pull on main to get the changes.
• if you are using the package manager to add CES, add CalibrateEmulateSample#main instead of just add CalibrateEmulateSample or just dev your local version
• ensure in either case that the EnsembleKalmanProcesses version is updated to 1.1.7 else call update in Pkg

Hopefully in the next few days I'll release a new version so just the add works. (I am still wanting to merge one other PR (#292) before releasing a new version)

Please re-open the issue or create more issues if you have other problems! Thanks for helping improve the code :)
