tf.contrib.metrics.streaming_mean_tensor( values, weights=None, metrics_collections=None, updates_collections=None, name=None )
Computes the element-wise (weighted) mean of the given tensors. (deprecated)
In contrast to the
streaming_mean function which returns a scalar with the
mean, this function returns an average tensor with the same shape as the
streaming_mean_tensor function creates two local variables,
count_tensor that are used to compute the average of
values. This average is ultimately returned as
mean which is an idempotent
operation that simply divides
For estimation of the metric over a stream of data, the function creates an
update_op operation that updates these variables and returns the
total with the reduced sum of the product of
weights, and it increments
count with the reduced sum of
None, weights default to 1. Use weights of 0 to mask values.
