TimeSeriesDataPoint

A TensorboardTimeSeries data point.

Fields
wallTimestring (Timestamp format)

Wall clock timestamp when this data point is generated by the end user.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples:"2014-10-02T15:01:23Z","2014-10-02T15:01:23.045123456Z" or"2014-10-02T15:01:23+05:30".

stepstring (int64 format)

Step index of this data point within the run.

valueUnion type
Value of this time series data point.value can be only one of the following:
scalarobject (Scalar)

A scalar value.

tensorobject (TensorboardTensor)

A tensor value.

A blob sequence value.

JSON representation
{"wallTime":string,"step":string,// value"scalar":{object (Scalar)},"tensor":{object (TensorboardTensor)},"blobs":{object (TensorboardBlobSequence)}// Union type}

Scalar

One point viewable on a scalar metric plot.

Fields
valuenumber

value of the point at this step / timestamp.

JSON representation
{"value":number}

TensorboardTensor

One point viewable on a tensor metric plot.

Fields
valuestring (bytes format)
versionNumberinteger

Optional. version number of TensorProto used to serializevalue.

JSON representation
{"value":string,"versionNumber":integer}

TensorboardBlobSequence

One point viewable on a blob metric plot, but mostly just a wrapper message to work around repeated fields can't be used directly withinoneof fields.

Fields
values[]object (TensorboardBlob)

List of blobs contained within the sequence.

JSON representation
{"values":[{object (TensorboardBlob)}]}
