Few occurrences of warnings.warn in the base code
There is few occurrences of warnings.warn
in the base code, mostly for deprecation warning.
Sometimes without the warnings
import.
A new bliss.common.deprecation
could be used instead.
A log_deprecation
could be created and used (to be consistent with the current BLISS logging system).
For non deprecation warning, log_warning
should be used.
