logging levels not set comprehensively (still get INFO messages with WARNING set)

Riproduci il report con binomial-rng.stan e bug.py, iniziando dalla configurazione di logging.getLogger('cmdstanpy') e dalla chiamata a CmdStanModel.sample. Traccia i nomi dei logger utilizzati per i messaggi segnalati e verifica che l'impostazione di WARNING sopprima l'output INFO senza influire sull'esecuzione del modello.

Summary:

I set the logger level to WARNING before compiling and running a model, but I still see INFO level warning messages.

Description:

Here's a simple reproducible example consisting of a Stan program and a Python script that can go in the same directory and run as shown below.

binomial-rng.stan:

data {
  int<lower=0> N;
  real<lower=0, upper=1> theta;
}
generated quantities {
  int<lower=0, upper=N> y = binomial_rng(N, theta);
}

bug.py

import cmdstanpy
import logging

logging.getLogger('cmdstanpy').setLevel(logging.WARNING)

N = 100
theta = 0.3
data = {'N': N, 'theta': theta}
model = cmdstanpy.CmdStanModel(stan_file = 'binomial-rng.stan')
sample = model.sample(data = data, seed=123,
                      iter_sampling = 10, iter_warmup = 0, chains = 1,
                      show_progress = False, show_console = False)

~/temp2$ python3 bug.py 
14:43:39 - cmdstanpy - INFO - CmdStan start processing
14:43:39 - cmdstanpy - INFO - Chain [1] start processing
14:43:39 - cmdstanpy - INFO - Chain [1] done processing
14:43:39 - cmdstanpy - INFO - deleting tmpfiles dir: /var/folders/b3/6h4t41094vz281j7nn48ws900001jv/T/tmpojw6vov9
14:43:39 - cmdstanpy - INFO - done

The same error arises if you set logging.ERROR instead of logging.WARNING.

@WardBrian suggested the problem might be that there are several loggers being used by CmdStanPy, but only some of them are getting their level set.

Context

I would like to silence all the DEBUG and INFO level messages in the context of constructing a quarto tutorial.
