Dear Monodet team,

Thank you for your work and I hope this message finds you well. I am writing to report an issue that I encountered while working with Monodet.
I have created a new environment with Python 3.6, PyTorch 1.5.0 and Detectron2 0.1.3 as per the instructions in the README file. However, I am still facing this issue.
from detectron2 import _C
ImportError: cannot import name '_C'
also i have used another method used your folder detectron2 but the same problem
Could you please help me with this problem? Any help or guidance would be greatly appreciated.

Thank you for your time and consideration.

Best regards,
