spyder compiler
During the study, the difficulties encountered first is to install python:
1. For me, it's white, do not know what platform or what uses python compiler.
2. Meanwhile, in the process of learning to see opencv in the course of the platform can be used python opencv language and have access, so using the compiler.
Download and install the configuration is complete, start learning basic programming python
