Compilations errors & julia version compatibility #204

Open elliottower opened 2 years ago

elliottower commented 2 years ago

Is there a recommended way to install/set up the environment for the current version of Omega?

Using julia 1.0.5 I am able to get Omega working, but unfortunately some of the example model notebooks do not work with this version of julia due to dependencies (e.g., LearnTimeSeries, which requires DifferentialEquations which does not work with julia 1.0).

Using julia 1.6 (LTS) or 1.7 (stable) I encountered similar issues to this previous issue, although with 1.7 I was finally able to precompile Omega using the workaround stated there of first installing an older version of Flux (0.9 led to errors for me so I did 0.8). However, when testing the built in distributions, I encountered this error:

My working environment for julia 1.0 is as follows (conda & IJulia are not necessary, just for ease of use to work with jupyter hub)

(v1.0) pkg> status
    Status `~/.julia/environments/v1.0/Project.toml`

  [7073ff75] IJulia v1.23.3
  [1af16e33] Omega v0.1.1

In order to get julia 1.0 and Omega 0.1 to work I had to delete all of the registries using this command rm(joinpath(homedir(), ".julia", "registries"); recursive=true), and then ] add Omega rather than develop. If I remember correctly v0.2 caused issues with julia 1.0, I just ran ] update and it is still using v0.1.1.

I actually was not able to get it to work using the workaround posted here either, seems to be a versioning issue
