It seems incorrect to treat I as the imaginary for Julia expressions since im is the Julia symbol for imaginary. This seems to be tripping up the symbolic ODE DSL since I is a valid Julia variable name and when it's used it gives a bad derivative
It has a safe recovery but IMO it can be handled better
I just did an epidemics workshop where people were making SIR models and this came up a lot (again, safe recovery and workarounds, but lots of warnings )

Can you open an issue at https://github.com/symengine/symengine about having a Julia parser?
We can extend the current parser to not do I and only im
