pm.find_MAP break with progressbar=False

Hi all,
I am trying to use find_MAP without the progress bar, but the error below occurs. Is it a bug?

AttributeError                            Traceback (most recent call last)
<ipython-input-42-7205282ebca5> in <module>()
----> 1 s = pm.find_MAP(progressbar=False, model=model)

/Users/catethos/anaconda3/lib/python3.6/site-packages/pymc3/tuning/ in find_MAP(start, vars, method, return_raw, include_transformed, progressbar, maxeval, model, *args, **kwargs)
    121             opt_result = minimize(cost_func, x0, method=method, jac=compute_gradient, *args, **kwargs)
    122             mx0 = opt_result["x"]  # r -> opt_result
--> 123    = cost_func.progress.n + 1
    124             cost_func.progress.update()
    125         except (KeyboardInterrupt, StopIteration) as e:

AttributeError: 'tqdm' object has no attribute 'n'

That is definitely a bug. The preferred place for bugs/issues like this is our Github issue tracker, if you wouldn’t mind posting there.

I have posted it in Github here

thanks for doing that!
