Hello,  
When I try to add the SymbolicRegression Pkg into my project, it says Unsatisfiable requirement. Kindly let me know how to proceed. This is the error that pops up:  
julia\> import Pkg; Pkg.add(“SymbolicRegression”)  
Resolving package versions…  
ERROR: Unsatisfiable requirements detected for package ProvenanceTracking [64b04e06]:

Thank you

Hello @SaiAhil,

Could you please provide the output of `Pkg.status()` for us as well as `versioninfo()`.

Kind regards,

The original compat error doesn’t show the underlying issue. The DeepPumas 0.9 release has a specific package version set pinned. For this particular release there is no way to install that package alongside DeepPumas.
