Removing logs of optimization in cross_validation

I am getting lots of logs while running the cross_validation using dask, Does anyone know a workaround for that thing?.
I tried to follow the solution from issue #223 , but I am unable to hide the log.

I was using this like this.

`with self.suppress_stdout_stderr():
df_cv = cross_validation(m, horizon='7 days', period='7 days', initial='500 days', parallel='dask')
`
