seems we have a hanging test for macOS and py3.8
https://github.com/PyTorchLightning/pytorch-lightning/pull/2044/checks?check_run_id=728728190
@williamFalcon it is already from master

[Borda]

@SkafteNicki this test is causing problem on macOS and py3.8
tests/loggers/test_all.py::test_logger_reset_correctly[Batch-size-Finder]
it is hanging there infinitely long and then the test is timeouted... any idea why?

[SkafteNicki]

@Borda not completly sure why it is failing specific on mac. Do you know how much RAM the machines have the test are running on? Since the test currently are evaluated on cpu, it is only when the RAM is filled up we get an OOM error and the search stops. Maybe it would help switching these tests to gpu, since the memory is smaller the test will be faster?

[Borda]

@SkafteNicki it is running on the very same servers, just different images...
also, it is failing on just one particular configuration...

[SkafteNicki]

@Borda am I reading the checks correct, that it works on mac with python 3.7 but not with python 3.8?

exactly... :]

This solves the issue with invalid accuracy tests...
