Yes, it seems that in pytorch we dont build with LAPACK for mobile. Hence the jar does not have lapack.
There are two alternatives I see.

If your inverse is on small matrix like 3x3 you can do python implementation of it as part of your model.
Build from source for mobile and add USE_LAPACK=1.

I think 1 can unblock you faster probably.
