Description
Case1: paddle.metric.accuracy
Reproduced Case：
import paddle
import numpy as np
array = np.array([], dtype=np.float32)
x = paddle.to_tensor(np.reshape(array, [0]), dtype='float32')
y = paddle.to_tensor([0, 0, 0, 0], dtype='int64')
paddle.metric.accuracy(input=x, label=y)Stack Trace Message：
