## Common Issues
### Do not use PIL
In order to read images in Python, make sure to use OpenCV (do not use PIL). We found that feeding a PIL image format to OpenPose results in the input image appearing in grey and duplicated 9 times (so the output skeleton appear 3 times smaller than they should be, and duplicated 9 times).
### Cannot Import Name PyOpenPose
The error in general is that PyOpenPose cannot be found (an error similar to: `ImportError: cannot import name pyopenpose`). Ensure first that `BUILD_PYTHON` flag is set to ON. If the error persists, check the following:
In the script you are running, check for the following line, and run the following command in the same location as where the file is

2. Functions or parameters renamed:
3. Main bugs fixed:
1. 90 and 270-degree rotations working again.
2. C++ tutorial API demos only try to cv::imshow the image if it is not empty (avoding the assert that it would trigger otherwise).
4. Changes/additions that affect the compatibility with the OpenPose Unity Plugin:
