I want to pip install cython_bbox on my windows, however, an error happened!
I have anaconda with python 3.7 in my computer before, and in its envs I created a new environment which has python3.6 to pip install cython_bbox for my own projects. However, it failed! Detailsare as follows.
First, in cmd, I cd to where the pip locates, in my computer is H:\Anaconda\anzhuang\envs\py36\Scripts,and then I code pip install cython_bbox -i https://pypi.tuna.tsinghua.edu.cn/simple,then errors become as follows.
