bug描述 Describe the Bug

基本环境

python: 3.10 GPU: NVIDIA A800 paddle commit id: c0b2c7d10e95988fd0b76b782a3fb56606579c0c

复现过程

安装paddle

git clone https://github.com/PaddlePaddle/Paddle.git
cd Paddle
mkdir build
cd build
cmake .. -DPY_VERSION=3.10 -DWITH_GPU=ON -WITH_TESTING=on
make -j$(nproc)
pip install python/dist/paddlepaddle_gpu-0.0.0-cp310-cp310-linux_x86_64.whl

运行testcase

# activate env
cd /Paddle/test/legacy_test
python test_empty_like_op.py
# error

错误原因

观察出错的testcase如下 看起来期望实现的功能是不可以把float64的类型转换为uint8类型，而实际底层支持这一功能

@penPenf28 CI 中单测都会跑的除非禁用掉，但这个并没有

CI 中全部单测是使用 ctest 运行的，请参考 https://www.paddlepaddle.org.cn/documentation/docs/zh/dev_guides/code_contributing_path_cn.html#bendibianyibingzhixingdanyuanceshi

也就是

ctest -R test_empty_like_op

ctest 执行时部分单测和直接 python 跑是有 diff 的，该单测的 diff 是因为该单测位于 STATIC_MODE_TESTING_LIST

https://github.com/PaddlePaddle/Paddle/blob/5ee37e19e454bb7c21da09ccfb62ca46144b50f0/tools/static_mode_white_list.py#L175

这意味着这些单测在执行前会 paddle.enable_static() 一下，以启用静态图模式（因为以前 Paddle 静态图是默认模式），如果你想要直接跑，相应地，在 test_empty_like_op.py 单测开始前加一个 paddle.enable_static() 即可，比如

 if __name__ == '__main__':
+    paddle.enable_static()
     unittest.main()

你好，之前的单测写得有问题，已提交修复pr删除了TestEmptyError：https://github.com/PaddlePaddle/Paddle/pull/64073
