[BUG]: Installation, Unsatisfiable requirements #362

Closed soerenab closed 1 year ago

What happened?

Hi Miles, Thank you for making PySR available!

I am facing an error during installation, when calling python3 -m pysr install:

julia.core.JuliaError: Exception 'Unsatisfiable requirements detected for package DynamicExpressions [a40a106e]:
 DynamicExpressions [a40a106e] log:
 ├─possible versions are: 0.1.0-0.4.2 or uninstalled
 └─restricted to versions 0.8 by SymbolicRegression [8254be44] — no versions left
   └─SymbolicRegression [8254be44] log:
     ├─possible versions are: 0.18.0 or uninstalled
     └─SymbolicRegression [8254be44] is fixed to version 0.18.0' occurred while calling julia code:
Pkg.add([sr_spec, clustermanagers_spec], io=stderr)

I successfully installed PySR about two month ago following your instructions (same command as above). From the error message, the problem seems to be that PySR requires SymbolicRegression==0.18.0 which in turn requires DynamicExpressions==0.8 which for some reason does not seem to be available.

System information:

Thanks for the bug report. Could you see whether the solutions here are any help? https://github.com/MilesCranmer/PySR/issues/27 thanks

MilesCranmer commented 1 year ago

Basically it might be your package server for Julia is not updating. Because the latest version of DynamicExpressions.jl is https://github.com/SymbolicML/DynamicExpressions.jl/releases/tag/v0.10.1 whereas your Julia thinks it is only 0.4.2 for some reason.

(It could also be if you happen to be using a local version of DynamicExpressions.jl?)

Indeed, this was the problem and the steps you linked solved it. Thanks a lot!

Awesome!
