examples/max_coverage.py - "TypeError: 'Prox' object is not callable" #5

Hey Steven,

Running examples/max_coverage.py also returns an error for me:

DN0a22a81f:examples mike$ python max_coverage.py
Traceback (most recent call last):
  File "max_coverage.py", line 24, in <module>
    prob.solve(method="NC-ADMM", parallel=False, verbose=True, polish_depth=0, restarts=1)

    x1 = prox(x0, rho_val)
TypeError: 'Prox' object is not callable

Am I on the wrong version of something? As far as I'm aware, I have the latest version of cvxpy and the latest version of ncvx. Note that I was able to successfully run examples/circle_packing.py.

Hi, I have the same problem.

Sorry for the super slow response. This is fixed now in source and on pip. It was because scsprox is out of date on pip. I've posted an issue asking the maintainer to update it.

This example works for me now 😄
