ImportError: cannot import name '_C' from 'detectron2'

Hi, I'm trying to run your demo.

I installed the pytorch environment follow your 'step-by-step installation.txt'. But when I use python demo/icdar2015_detection.py to run the demo. I came across this problem .

Traceback (most recent call last):
  File "demo/icdar2015_detection.py", line 12, in <module>
    from detectron2.data.detection_utils import read_image

Do you know why? Thanks!

@TianhaoFu I have the same problem, have you solved it?

I run python setup.py build develop successfully, but it still shows the error.
