Logging¶
Logging is a crucial part of the optimization, which should be customizable by the user. This page gives you the overview how to customize the logging experience with SMAC.
Level¶
The easiest way to change the logging behaviour is to change the level of the global logger. SMAC does this for you
if you specify the logging_level in any facade.
smac = Facade(
...
logging_level=20,
...
)
The table shows you the specific levels:
Name |
Level |
|---|---|
0 |
SHOW ALL |
10 |
DEBUG |
20 |
INFO |
30 |
WARNING |
40 |
ERROR |
50 |
CRITICAL |
Custom File¶
Sometimes, the user wants to disable or highlight specify modules. You can do that by passing a custom yaml file to the facade instead.
smac = Facade(
...
logging_level="path/to/your/logging.yaml",
...
)
The following file shows you how to display only error messages from the intensifier but keep the level of everything else on INFO:
version: 1
disable_existing_loggers: false
formatters:
simple:
format: '[%(levelname)s][%(filename)s:%(lineno)d] %(message)s'
handlers:
console:
class: logging.StreamHandler
level: INFO
formatter: simple
stream: ext://sys.stdout
loggers:
smac.intensifier:
level: ERROR
handlers: [console]
root:
level: INFO
handlers: [console]
