Module: tf.contrib.summary

Defined in tensorflow/contrib/summary/summary.py.

TensorFlow Summary API v2.

The operations in this package are safe to use with eager execution turned on or off. It has a more flexible API that allows summaries to be written directly from ops to places other than event log files, rather than propagating protos from tf.summary.merge_all to tf.summary.FileWriter.

To use with eager execution enabled, write your code as follows:

global_step = tf.train.get_or_create_global_step() summary_writer = tf.contrib.summary.create_file_writer( train_dir, flush_millis=10000) with summary_writer.as_default(), tf.contrib.summary.always_record_summaries(): # model code goes here # and in it call tf.contrib.summary.scalar("loss", my_loss) # In this case every call to tf.contrib.summary.scalar will generate a record # ...

To use it with graph execution, write your code as follows:

global_step = tf.train.get_or_create_global_step() summary_writer = tf.contrib.summary.create_file_writer( train_dir, flush_millis=10000) with summary_writer.as_default(), tf.contrib.summary.always_record_summaries(): # model definition code goes here # and in it call tf.contrib.summary.scalar("loss", my_loss) # In this case every call to tf.contrib.summary.scalar will generate an op, # note the need to run tf.contrib.summary.all_summary_ops() to make sure these # ops get executed. # ... train_op = ....

with tf.Session(...) as sess: tf.global_variables_initializer().run() tf.contrib.summary.initialize(graph=tf.get_default_graph()) # ... while not_done_training: sess.run([train_op, tf.contrib.summary.all_summary_ops()]) # ...

Classes

class SummaryWriter: Encapsulates a stateful summary writer resource.

Functions

always_record_summaries(...): Sets the should_record_summaries Tensor to always true.

audio(...): Writes an audio summary if possible.

create_db_writer(...): Creates a summary database writer in the current context.

create_file_writer(...): Creates a summary file writer in the current context.

create_summary_file_writer(...): Please use tf.contrib.summary.create_file_writer.

eval_dir(...): Construct a logdir for an eval summary writer.

flush(...): Forces summary writer to send any buffered data to storage.

generic(...): Writes a tensor summary if possible.

graph(...): Writes a TensorFlow graph to the summary interface.

histogram(...): Writes a histogram summary if possible.

image(...): Writes an image summary if possible.

import_event(...): Writes a tf.Event binary proto.

initialize(...): Initializes summary writing for graph execution mode.

never_record_summaries(...): Sets the should_record_summaries Tensor to always false.

record_summaries_every_n_global_steps(...): Sets the should_record_summaries Tensor to true if global_step % n == 0.

scalar(...): Writes a scalar summary if possible.

should_record_summaries(...): Returns boolean Tensor which is true if summaries should be recorded.

summary_writer_initializer_op(...): Graph-mode only. Returns the list of ops to create all summary writers.
