Computes the percentage of times that predictions matches labels.

tf.contrib.metrics.accuracy(
    predictions, labels, weights=None, name=None
)

predictions the predicted values, a Tensor whose dtype and shape matches 'labels'.
labels the ground truth values, a Tensor of any shape and bool, integer, or string dtype.
weights None or Tensor of float values to reweight the accuracy.
name A name for the operation (optional).

Accuracy Tensor.

ValueError if dtypes don't match or if dtype is not bool, integer, or string.
