tf.summary.SummaryWriter

Interface representing a stateful summary writer object.

Methods

as_default

View source

Returns a context manager that enables summary writing.

For convenience, if step is not None, this function also sets a default value for the step parameter used in summary-writing functions elsewhere in the API so that it need not be explicitly passed in every such invocation. The value can be a constant or a variable.

For example, step can be used as:

with writer_a.as_default(step=10):
  tf.summary.scalar(tag, value)   # Logged to writer_a with step 10
  with writer_b.as_default(step=20):
    tf.summary.scalar(tag, value) # Logged to writer_b with step 20
  tf.summary.scalar(tag, value)   # Logged to writer_a with step 10

Args
step An int64-castable default step value, or None. When not None, the current step is captured, replaced by a given one, and the original one is restored when the context manager exits. When None, the current step is not modified (and not restored when the context manager exits).
