Refer to the installation tutorial of station b

Need to pay attention to the following bugs

1. There is a problem in the last step:

warnings.warn('Error checking compiler version for {}: {}'.format(compiler, error))

Solution:
Install Microsoft C++ Environment

2. The problem still occurs after the last step:

编译的过程中, 运行 python setup.py develop
跳出了很多代码, 最后报错

3. There is a problem with the first example:
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows
Solution:
Just reinstall opencv
