pytest fails in bench\test_monitor.py

[sabibria]

All other tests appear to pass but bench\test_monitor.py fails as follows:

E FileNotFoundError: [Errno 2] No such file or directory: '/tmp/baselines-test-e29ffc5a-0bac-4b9f-8f78-e72428b489ec.monitor.csv'

Extended pytest output below. Any idea how to fix this? Running on Windows 10.

I got the same error. anyone has a clue?

I solved it. the hard-coded filename could not be recognized on Window OS, should change "'/tmp/baselines-test-.csv':" into os.path.join("tmp", "baselines-test-.csv", then it worked
