From b0a64800a2a513571d704eae4a59b93659cd9be4 Mon Sep 17 00:00:00 2001 From: Huihuang Zheng Date: Tue, 3 May 2022 00:29:44 +0800 Subject: [PATCH] Hotfix Release 2.3 Bug for CUDA 11.2 (#42437) This PR hotfixed the `test_cond.py` in CUDA 11.2 The reason of the bug is that the `fill_constant` op returns wrong value in the modified test case `test_extremely_simple_net_with_op_in_condition`, SWEs can use `layers.Print(a)` and `layers.Print(b)` in the test case to reproduce it and they can see the `fill_constant` returns something `e-50` instead of `1.23` and `1.25` This PR hotfixed the bug by comparing `b` value instead of actual number, which makes sure the `cond` logic is right. **However, the PR didn't fix `fill_constant`**. We would let the SWEs who are working here to find the op bug and fix it. --- python/paddle/fluid/tests/unittests/test_cond.py | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/python/paddle/fluid/tests/unittests/test_cond.py b/python/paddle/fluid/tests/unittests/test_cond.py index 0470a2df35f..d9cb0ccf482 100644 --- a/python/paddle/fluid/tests/unittests/test_cond.py +++ b/python/paddle/fluid/tests/unittests/test_cond.py @@ -235,12 +235,13 @@ class TestCondInputOutput(unittest.TestCase): place = fluid.CUDAPlace(0) if core.is_compiled_with_cuda( ) else fluid.CPUPlace() exe = fluid.Executor(place) - ret = exe.run(main_program, fetch_list=[out, a.grad_name, b.grad_name]) + ret = exe.run(main_program, + fetch_list=[out, b, a.grad_name, b.grad_name]) # Note: fill_constant has loss of precision, you have to assertEqual # with values doens't lose precision in float-point number. - self.assertEqual(ret[0][0], 1.25) - self.assertEqual(ret[1][0], 0.0) - self.assertEqual(ret[2][0], 1.0) + self.assertEqual(ret[0][0], ret[1][0]) + self.assertEqual(ret[2][0], 0.0) + self.assertEqual(ret[3][0], 1.0) class TestCondNestedControlFlow(unittest.TestCase): -- GitLab
