Methods

call(
trajectory
)
init_variables

init_variables()
Initializes this Metric's variables.
Should be called after variables are created in the first execution
of __call__(). If using graph execution, the return value should be
run() in a session before running the op returned by __call__().
(See example above.)
| Returns |
|---|
|
If using graph execution, this returns an op to perform the
initialization. Under eager execution, the variables are reset to their
initial values as a side effect and this function returns None.

result

result()
Computes and returns a final value for the metric.
tf_summaries
View source
tf_summaries(
train_step=None, step_metrics=()
)
Generates summaries against train_step and all step_metrics.
| Args |
|---|
train_step
|
(Optional) Step counter for training iterations. If None, no
metric is generated against the global step.
|
step_metrics
|
(Optional) Iterable of step metrics to generate summaries
against.
|
| Returns |
|---|
|
A list of summaries.
|
__call__
View source
__call__(
*args, **kwargs
)
Returns op to execute to update this metric for these inputs.
Returns None if eager execution is enabled.
Returns a graph-mode function if graph execution is enabled.
| Args |
|---|
*args
|
|
**kwargs
|
A mini-batch of inputs to the Metric, passed on to call().
