torchnet.logger¶
Loggers provide a way to monitor your models. For example, the MeterLogger
class
provides easy meter visualizetion with Visdom ,
as well as the ability to print and save meters with the ResultsWriter
class.
For visualization libraries, the current loggers support Visdom
, although TensorboardX
would also be simple to implement.
MeterLogger¶
-
class
torchnet.logger.
MeterLogger
(server='localhost', env='main', port=8097, title='DNN', nclass=21, plotstylecombined=True)[source]¶ Bases:
object
A class to package and visualize meters.
Parameters: - server – The uri of the Visdom server
- env – Visdom environment to log to.
- port – Port of the visdom server.
- title – The title of the MeterLogger. This will be used as a prefix for all plots.
- nclass – If logging for classification problems, the number of classes.
- plotstylecombined – Whether to plot train/test curves in the same window.
VisdomLogger¶
Logging to Visdom server
-
class
torchnet.logger.visdomlogger.
BaseVisdomLogger
(fields=None, win=None, env=None, opts={}, port=8097, server='localhost')[source]¶ Bases:
torchnet.logger.logger.Logger
The base class for logging output to Visdom.
*THIS CLASS IS ABSTRACT AND MUST BE SUBCLASSED*
Note that the Visdom server is designed to also handle a server architecture, and therefore the Visdom server must be running at all times. The server can be started with $ python -m visdom.server and you probably want to run it from screen or tmux.
-
log_state
(state)[source]¶ Gathers the stats from self.trainer.stats and passes them into self.log, as a list
-

¶
-
-
class
torchnet.logger.visdomlogger.
VisdomLogger
(plot_type, fields=None, win=None, env=None, opts={}, port=8097, server='localhost')[source]¶ Bases:
torchnet.logger.visdomlogger.BaseVisdomLogger
A generic Visdom class that works with the majority of Visdom plot types.
-
class
torchnet.logger.visdomlogger.
VisdomPlotLogger
(plot_type, fields=None, win=None, env=None, opts={}, port=8097, server='localhost', name=None)[source]¶
-
class
torchnet.logger.visdomlogger.
VisdomSaver
(envs=None, port=8097, server='localhost')[source]¶ Bases:
object
Serialize the state of the Visdom server to disk. Unless you have a fancy schedule, where different are saved with different frequencies, you probably only need one of these.
-
class
torchnet.logger.visdomlogger.
VisdomTextLogger
(fields=None, win=None, env=None, opts={}, update_type='REPLACE', port=8097, server='localhost')[source]¶ Bases:
torchnet.logger.visdomlogger.BaseVisdomLogger
Creates a text window in visdom and logs output to it.
The output can be formatted with fancy HTML, and it new output can be set to ‘append’ or ‘replace’ mode.
Parameters: - fields – Currently not used
- update_type – One of {‘REPLACE’, ‘APPEND’}. Default ‘REPLACE’.
For examples, make sure that your visdom server is running.
Example
>>> notes_logger = VisdomTextLogger(update_type='APPEND') >>> for i in range(10): >>> notes_logger.log("Printing: {} of {}".format(i+1, 10)) # results will be in Visdom environment (default: http://localhost:8097)
