Writes a generic summary to the default SummaryWriter if one exists.
tf.summary.write(
tag, tensor, step=None, metadata=None, name=None
)
This exists primarily to support the definition of type-specific summary ops
like scalar() and image(), and is not intended for direct use unless defining
a new type-specific summary op.
Args |
tag
|
string tag used to identify the summary (e.g. in TensorBoard), usually
generated with tf.summary.summary_scope
|
tensor
|
the Tensor holding the summary data to write or a callable that
returns this Tensor. If a callable is passed, it will only be called when
a default SummaryWriter exists and the recording condition specified by
record_if() is met.
|
step
|
Explicit int64 -castable monotonic step value for this summary. If
omitted, this defaults to tf.summary.experimental.get_step() , which must
not be None.
|
metadata
|
Optional SummaryMetadata, as a proto or serialized bytes
|
name
|
Optional string name for this op.
|
Returns |
True on success, or false if no summary was written because no default
summary writer was available.
|
Raises |
ValueError
|
if a default writer exists, but no step was provided and
tf.summary.experimental.get_step() is None.
