Hello,

Regarding the capabilities of SciPy.jl, it seems it cannot incorporate the constraints SciPy.NonlinearConstraints?

Thanks

Julia has a good range of optimization libraries. You should not need to call `spicy.optimize`.

SciPy.jl uses PyCall.jl, which allows you to call essentially any Python API from Julia. So, you should be able to access any `scipy.optimize` API, but you may have to dig through the wrapper functions of SciPy.jl to figure out how to access it.

Alternatively, you should be able to import and call `scipy.optimize` directly via PyCall.jl (or via PythonCall.jl), without using SciPy.jl. Then you can just directly translate the Python API calls into Julia.
