You can call Julia’s C-API `jl_init_with_image` directly via ctypes (see [AOT compiling using PackageCompiler - #5 by tkf](https://discourse.julialang.org/t/aot-compiling-using-packagecompiler/16911/5)) and then I think you can setup PyJulia with `init_julia=False` (not tested).

But I want to add more direct API for this: [https://github.com/JuliaPy/pyjulia/issues/199](https://github.com/JuliaPy/pyjulia/issues/199)
