Running OWENS in a python wrapper

[kevmoor]

Desire is to run Julia functions directly in Python WEIS, see https://discourse.julialang.org/t/calling-julia-functions-from-python/6885/2

Would possibly still start with file dump, system run, and then read file

Need others to be able to run this easily.

This works, assuming you have julia and OWENS running. It took just a few minutes to implement.

# juliaup update
# pip --trusted-host pypi.org --trusted-host files.pythonhosted.org install juliacall
from juliacall import Main as jl
from juliacall import Pkg as jlPkg

jlPkg.activate("../../../")  # relative path to the folder where `MyPack/Project.toml` should be used here 

jl.seval("using OWENS")

testdata = jl.OWENS.runOWENS(jl.OWENS.MasterInput("./sampleOWENS.yml"),"./").to_numpy()

[kevmoor]

So, the next step is aligning the inputs and outputs with potential design optimization needs, which is being defined in #18

Need to review with NREL folks and then this should be completed.

Hi Kevin,

I may need some on-line support with running this tomorrow. Here are a few things I've tried:

Running as-is give me:

ERROR: LoadError: ArgumentError: Package GyricFEA [3cd7cb04-a333-4aed-a1f1-c87982f3ae73] is required but does not seem to be installed:
 - Run `Pkg.instantiate()` to install all recorded dependencies.

So, I added a jlPkg.instantiate() to the script.

Then, I get a

juliacall.JuliaError: expected package `PreComp [19f83dec]` to be registered
Stacktrace:

I tried several other things we can go over, but never get further than the PreComp registration notice.

Any ideas?

Hi Daniel,

The dependency tree needs to be satisfied. Until the repos can be open sourced and registered with the package manager, they need to be installed manually, in the order specified.

If you have already done that, and are using visual studio, sometimes visual studio activates the current directory’s project.toml environment, instead of the overall julia 1.10 etc environment. If this is the case, you can simply click on the current environment in the bottom ribbon and select the desired environment. Running directly from the terminal would also remove any issues caused by the ide.

Okay, I made some progress on this:

Within the python script, I had to jlPkg.activate('/Users/dzalkind/.julia/environments/v1.9/Project.toml')

In chatting with @yqliaohk, I learned that she had installed several dependencies in developer mode. Perhaps that's also another source of our differences in set up?

[kevmoor]

Great! Maybe, mine are in developer mode as well, so that could be it.

Also, I just pushed a patch to the dev branch of OWENS.jl that fixes the post processing errors. If you have a developer install of owens (cloned locally, cd path2directory/OWENS.jl, julia, ] dev .) then you can just pull and check out the branch and then it will use the branch.
