Routine issues are posted here. Below are some longer term issues and limitations.
For users of Mac OS using Julia 1.3 or higher, using ScikitLearn models can lead to unexpected MKL errors due to an issue not related to MLJ. See this Julia Discourse discussion and this issue for context.
A temporary workaround for this issue is to force the installation of
an older version of the OpenSpecFun_jll
library. To install an
appropriate version, activate your MLJ environment and run
using Pkg;
Pkg.add(PackageSpec(url="https://github.com/tlienart/OpenSpecFun_jll.jl"))
See
here. Workaround:
Instead of XGBoost
models (the chief known case) use models from the
pure Julia package EvoTrees
.
