Prophet: Suppress pystan output

[jimanvlad]

Hi,

Is there anyway to suppress the pystan output? It's making my console unmanageable when I need to do 100s of simulations.

E.g.:

STAN OPTIMIZATION COMMAND (LBFGS)
init = user
save_iterations = 1
init_alpha = 0.001
tol_obj = 1e-12
tol_grad = 1e-08
tol_param = 1e-08
tol_rel_obj = 10000
tol_rel_grad = 1e+07
history_size = 5
seed = 608934640
initial log joint probability = -4.96167
    Iter      log prob        ||dx||      ||grad||       alpha      alpha0  # evals  Notes 
      92       60.2419   8.15566e-09       502.912      0.6088      0.6088      121   
Optimization terminated normally: 
  Convergence detected: absolute parameter change was below tolerance

This is surprisingly challenging. Working on it...

Redirect the output to /dev/null or some file?

This would also be very useful for R. I'm using prophet inside an R Markdown document, and the Stan printout is just not an option. Thanks!

Had the same issue and figured that the output you see comes from calling rstan::optimizing() and rstan::sampling(). Here is a similar issue in RStan

[RobertMyles]

Using results = "hide" in the knitr code chunk options works, for those of you using RMarkdown.

Any solution for python though?

@jimanvlad I just added a decorator to #223 that will suppress the output.

I'm going to close this to merge it with #223. In the latest version of rstan, optimizer output is suppressed by default. Pystan still doesn't have an option to suppress optimizer output, but there is a workaround in #223 to suppress the output with a wrapper function.
