int64类型的matmul操作报错。

[Tlntin]

bug描述 Describe the Bug

代码

import paddle
x1 = paddle.Tensor(np.arange(9).reshape(3, 3))
y1 = paddle.Tensor(np.arange(12).reshape(3, 4))
z = paddle.matmul(x1, y1)

报错内容

NotFoundError: Operator matmul_v2 does not have kernel for {data_type[int64_t]; data_layout[Undefined(AnyLayout)]; place[Place(gpu:0)]; library_type[PLAIN]}.
  [Hint: Expected kernel_iter != kernels.end(), but received kernel_iter == kernels.end().] (at /home/ubuntu/Documents/Paddle/paddle/fluid/imperative/prepared_operator.cc:419)
  [operator < matmul_v2 > error]

临时解决方案

• 将数据改成float32

z = paddle.matmul(paddle.cast(x1, paddle.float32), paddle.cast(y1, paddle.float32))

建议解决方案

• 重写一下matmul_v2 算子，增加int64类型计算，顺便检查一下其它类型是否有类似错误。
