Can't import _pytest.python.transfer_markers

[ln-nicolas]

Hello,

I have pytest 4.1.0 installed, and after installing pytest-asyncio i got this error trying to run pytest

  File "/usr/local/lib/python3.5/dist-packages/pytest_asyncio/plugin.py", line 8, in <module>
    from pytest.python import transfer_markers
ImportError: cannot import name 'transfer_markers'

I bypassed this problem installing pytest 4.0.2

pip install pytest==4.0.2

But i think it still a bug for the 4.1.0 version

Best regards

this is a bug in pytest_asyncio

marker transfer was never a public api, and it got removed as it created broken data all over the place
the import line looks edited, as transfer_markers can only be imported from the internals of pytest

i just recalled i should actually move it
