What is the error message and what is the code?
I defined a simple model, just one tight-binding orbital with nearest neighbors hops on a cubic lattice. With this model I still get the error message about fermionic operators.
If I do the opposite, i.e. remove from the Kondo lattice the hopping term with the corresponding bonds, the effect is:

The lattice and model libraries are attached to this message.

PS. Obviously, the problem is that the error messages do not show which term/operator/etc is the source of the problem.
