J1J2 exact example leads to NaN values

[orsharir]

The simple J1-J2 example with exact optimization (j1j2_2d_exact_4.py) seems to lead to NaN / overflow values after a few iterations:

/cs/labs/shashua/ors07/Pyket/src/pyket/optimization/exact_variational.py:92: RuntimeWarning: overflow encou$
tered in multiply
np.multiply(np.real(self.naive_local_energy_minus_energy), np.real(self.naive_local_energy_minus_energy), out=self.naive_local_energy_minus_energy_squared)
/cs/labs/shashua/ors07/Pyket/src/pyket/optimization/exact_variational.py:93: RuntimeWarning: invalid value encountered in multiply
np.multiply(self.naive_local_energy_minus_energy_squared, self.exact_variational.probs, out=self.probs_mult_local_energy_variance)

I still play with these models when i finish i will update the learning rate to good one that will converge

Is this example fixed? can we close this issue?
