"""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:

```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()])
    # ...
```
