示例1: test_precision_op
# 需要導入模塊: import tf_metrics [as 別名]
# 或者: from tf_metrics import precision [as 別名]
def test_precision_op(generator_fn, y_true_all, y_pred_all, pos_indices,
average):
# Precision on the whole dataset
pr_sk = precision_score(
y_true_all, y_pred_all, pos_indices, average=average)
# Create Tensorflow graph
ds = tf.data.Dataset.from_generator(
generator_fn, (tf.int32, tf.int32), ([None], [None]))
