divide by zero
In the warmup algorithm for the Ptychography experiment, you get a divide by zero error:
Running warmup algorithm DRl /home/rluke1/work/git/ProxPython/demos/../proxtoolbox/proxoperators/fourier.py:69: RuntimeWarning: divide by zero encountered in true_divide tmp = u_hat_sq / self.data_sq[j]
This does not seem to kill the run, but probably should be dealt with.
