metric_cosine_proximity() is deprecated and will be removed in a future
version. Please update your code to use metric_cosine_similarity() if
possible. If you need the actual function and not a Metric object, (e.g,
because you are using the intermediate computed values in a custom training
loop before reduction), please use loss_cosine_similarity() or
tensorflow::tf$compat$v1$keras$metrics$cosine_proximity()
metric_cosine_proximity(y_true, y_pred)Tensor of true targets.
Tensor of predicted targets.
