Describe

Logic运算包括以下算子：logical_and、logical_or、logical_xor

• 不支持broadcast
• 按目前paddle不支持braodcast进行验证，当两个输入tensor维度不相等时应该报错。

测试代码：

from __future__ import print_function

import op_test
import unittest
import numpy as np
import paddle
import paddle.fluid as fluid
from paddle.static import Program, program_guard


def create_test_class(op_type, callback, binary_op=True):
    class Cls(op_test.OpTest):
        def setUp(self):
            a = np.random.choice(a=[True, False], size=(10, 7)).astype(bool)
            if binary_op:
                b = np.random.choice(a=[True, False], size=(10, 7)).astype(bool)
                c = callback(a, b)
            else:

Thanks for your contribution!
Please wait for the result of CI firstly. See Paddle CI Manual for details.

Tiny English grammar issue:

"but receive" -> "but received"

The Variable's was received in the past, not a common thing.

I found most of PaddlePaddle codes used "but received", few of them used "but receive", please correct it.

thx
