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: ```python 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: ```python 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()]) # ... ``` """ from __future__ import absolute_import from __future__ import division from __future__ import print_function # pylint: disable=unused-import from tensorflow.python.ops.summary_ops_v2 import all_summary_ops from tensorflow.python.ops.summary_ops_v2 import always_record_summaries from tensorflow.python.ops.summary_ops_v2 import audio from tensorflow.python.ops.summary_ops_v2 import create_db_writer from tensorflow.python.ops.summary_ops_v2 import create_file_writer from tensorflow.python.ops.summary_ops_v2 import create_summary_file_writer from tensorflow.python.ops.summary_ops_v2 import eval_dir from tensorflow.python.ops.summary_ops_v2 import flush from tensorflow.python.ops.summary_ops_v2 import generic from tensorflow.python.ops.summary_ops_v2 import graph from tensorflow.python.ops.summary_ops_v2 import histogram from tensorflow.python.ops.summary_ops_v2 import image from tensorflow.python.ops.summary_ops_v2 import import_event from tensorflow.python.ops.summary_ops_v2 import initialize from tensorflow.python.ops.summary_ops_v2 import never_record_summaries from tensorflow.python.ops.summary_ops_v2 import record_summaries_every_n_global_steps from tensorflow.python.ops.summary_ops_v2 import scalar from tensorflow.python.ops.summary_ops_v2 import should_record_summaries from tensorflow.python.ops.summary_ops_v2 import summary_writer_initializer_op from tensorflow.python.ops.summary_ops_v2 import SummaryWriter
