error on building the zed sdk for python

[LearningVision]

I have tried to open the stereo video .svo file in python.
I have download the zed-sdk 2.1(for windows 64x) and then tried to build the zed-python package.
But I got error like as follow.
I think I installed the SDK and I can display the .svo file with zed explorer.exe

Hi,
It seems that the ZED SDK is not detected since you have "Error: you must install the ZED SDK". Try reinstalling it and reboot.
Then you can also test the C++ samples and the other tools (ZEDFu or ZED Depth Viewer).

Hi,
I got a same error.
This will be caused because cython version is old. please check your python version by

pip freeze

and if your python is not 0.26, update your cython by

pip install cython==0.26
