Build the Environment
Because Ubuntu has it’s own python2 and python3, what I need to finish is import those module.
pip
pip is a tools to install some software and package
anaconda
if you use python2 in your work, you should install anaconda2.X(issue).
if you use python3 in your work, you should install anaconda3.X(issue).
opencv-python
It is a difficult problem for me because my network is not good. Thus I cost much time on it.
you can install it by the following command in the filefolder of anaconda2 or anaconda3;
pip install opencv-python
if the enviroment is not good, you can change one and try again.
