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:
代码语言：javascript复制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:
代码语言：javascript复制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: Interface representing a stateful summary writer object.
Functions
- all_summary_ops(...): Returns all V2-style summary ops defined in the current default graph.
- 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 under the given name.
- create_summary_file_writer(...): Please use tf.contrib.summary.create_file_writer. (deprecated)
- 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.compat.v1.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.
