deepzoom_tile.py Issue

[Kathleen Sucipto]

Hi Benjamin,


I finally found the problem. I only checked the version for
python-openslide and not the openslide library itself; turns out mine was
v3.4.0 and the other was v3.4.1. It now works fine after upgrading to
v3.4.1.

Thank you so much for your reply!
