At the function example_TEBD_gs_tf_ising_infinite, the energy per site is calculated as

E = np.sum(M.bond_energies(psi))

I think you missed 1/2 here.
It can be clearly seen at the final results on the relative error.

Thanks for pointing it out, I've updated it on the master branch.
Unfortunately, it didn't make it into the release of v0.6.0 any more, which I packed last Friday :?
