Interface OnlineExperiment

All Superinterfaces:

AutoCloseable, Experiment

All Known Implementing Classes:

OnlineExperimentImpl

public interface OnlineExperiment
extends Experiment

The OnlineExperiment should be used to asynchronously update data of your Comet.ml experiment.

This experiment type allows you to automatically intercept StdOut and StdErr streams and send them to the Comet.ml. Use the setInterceptStdout() to start automatic interception of StdOut and the stopInterceptStdout() to stop.

Also, it is possible to use setStep(long), setEpoch(long), and setContext(String) which will bbe automatically associated with related logged data records.

Method Detail

setInterceptStdout

void setInterceptStdout()
                 throws IOException

Turn on intercept of stdout and stderr and the logging of both in Comet.

Throws:

IOException - if an I/O exception occurs.

stopInterceptStdout

void stopInterceptStdout()
                  throws IOException

Turn off intercept of stdout and stderr and turns off their logging in Comet.

Throws:

IOException - if an I/O exception occurs.

setStep

void setStep(long step)

Sets the current step for the experiment. This is used when logging metrics and params.

Parameters:

step - the current step of the experiment.

nextStep

void nextStep()

Increments the step that the experiment is on.

getStep

long getStep()

Gets the current step as recorded by the Experiment object locally.

Returns:

the current step of the experiment

setEpoch

void setEpoch(long epoch)

Sets the current epoch for the experiment.

Parameters:

epoch - the current epoch for the experiment.

nextEpoch

void nextEpoch()

Increments the epoch that the experiment is on.

getEpoch

long getEpoch()

Gets the current epoch as recorded by the Experiment object locally.

Returns:

the current epoch of the experiment.

setContext

void setContext(String context)

Sets the context identifier for any logs and uploaded files.

Parameters:

context - the context identifier to be associated with any log records, files, and assets.

getContext

String getContext()

Gets the current context identifier as recorded in the OnlineExperiment object locally.

Returns:

the current context which associated with log records of this experiment.

logMetric

void logMetric(String metricName,
               Object metricValue,
               long step)

Logs a metric with Comet. For running experiment updates current step to one from param! Metrics are generally values that change from step to step.

Parameters:

metricName - The name for the metric to be logged

metricValue - The new value for the metric. If the values for a metric are plottable we will plot them

step - The current step for this metric, this will set the given step for this experiment

logMetric

void logMetric(String metricName,
               Object metricValue)

logParameter

void logParameter(String parameterName,
                  Object paramValue)

Logs a param with Comet under the current experiment step. Params should be set at the start of the experiment.

Parameters:

parameterName - The name of the param being logged

paramValue - The value for the param being logged

logLine

void logLine(String line,
             long offset,
             boolean stderr)

Send output logs to Comet.

Parameters:

line - Text to be logged

offset - Offset describes the place for current text to be inserted

stderr - the flag to indicate if this is StdErr message.

uploadAsset

void uploadAsset(File asset,
                 String fileName,
                 boolean overwrite,
                 long step)

Upload an asset under the current experiment step to be associated with the experiment, for example the trained weights of a neural net.

Parameters:

asset - The asset to be stored

fileName - The file name under which the asset should be stored in Comet. E.g. "someFile.txt"

overwrite - Whether to overwrite files of the same name in Comet

step - The step to be associated with asset

uploadAsset

void uploadAsset(File asset,
                 String fileName,
                 boolean overwrite)

                    boolean recursive,
                    ExperimentContext context)

Logs all the files located in the given folder as assets.

Parameters:

folder - the folder you want to log.

logFilePath - if true, log the file path with each file.

recursive - if true, recurse the folder.

context - the experiment context to be associated with the logged assets.

logAssetFolder

void logAssetFolder(File folder,
                    boolean logFilePath,

logRemoteAsset

void logRemoteAsset(URI uri,

                    Map<String,Object> metadata,
                    ExperimentContext context)

Logs a Remote Asset identified by a URI. A Remote Asset is an asset but its content is not uploaded and stored on Comet. Rather a link for its location is stored, so you can identify and distinguish between two experiment using different version of a dataset stored somewhere else.

Parameters:

uri - the URI pointing to the remote asset location. There is no imposed format, and it could be a private link.

fileName - the optional "name" of the remote asset, could be a dataset name, a model file name.

overwrite - if true will overwrite all existing assets with the same name.

metadata - Some additional data to attach to the remote asset. The dictionary values must be JSON compatible.

context - the experiment context to be associated with the logged assets.
