mindspore.ops.ScalarSummary

class mindspore.ops.ScalarSummary

This operator will put a scalar to a summary file with protocol buffer format. It must be used with SummaryRecord or SummaryCollector, which specify the directory of the summary file. The summary file can be loaded and shown by MindInsight, see MindInsight documents for details.

Inputs:

• name (str) - The name of the input variable, it must not be an empty string.

• value (Tensor) - The value of scalar, and the dim of value must be 0 or 1.

Raises

• TypeError – If name is not a str.

• TypeError – If value is not a Tensor.

• ValueError – If dim of value is greater than 1.

Supported Platforms:

Ascend GPU CPU
