ops test core dump

[BingWin789]

Hi:
I compiled the hdrnet ops under python 3.5.2 (virtualenv) tensorflow 1.8.0 CUDA 10 cuDNN 7.1.4 ubuntu 16.04. Then I test ops by test_ops.py. The first two tests are passed. But the third test 'test_grid_gradient' encountered a 'core dump' error. The detail infomation is as follows:

`test/ops_test.py Fatal Python error: Aborted

I want to know if I should modify source code of bilateral slice to adapt to tf1.8 or just I tested it in a wrong way. Thanks in advance.

I have never tested it on 1.8, so it is possible this version introduced breaking C++ API changes. Unfortunately, I will not have time to look into this any time soon.

Hi, what is the version of tf and cuda that you have tested? I make it to adapt tf2.1 ,but the gradient is not right.Thanks.

[eduardinjo]

@mygmyg Do you mean that tf2.1 produces incorrect results? I upgraded to tf1.14, also most of the tests gave 'core dump' errors but it still converges to reasonable output although I haven't checked if all values are correct.

@eduardinjo I encountered
Check failed: work_element_count > 0 (-1072000000 vs. 0)
Aborted (core dumped)
when I run ops_test.py, did you resolve this problem?

[tzhong518]

I'm using 1.13. Not sure if is the same problem but I also met FATAL ERROR when using py.test to run the test.

I added if name == 'main' func in ops_test and used python to run it, which seemed to work.
