Time:2020-2-11

There are multiple versions of Python in Ubuntu system, so it is inevitable to encounter errors in environment variables when using it, especially when running scripts automatically. Especially in the past month, all of the lab’s partners have been devoted to python. In order to help young people quickly build their own Python environment, the author wrote this tutorial. Of course, if there is no problem with Ubuntu’s own python, you can skip the installation of anaconda.

Anaconda

Anaconda refers to an open source Python distribution, which contains more than 180 science packages such as CONDA, Python and their dependencies. Because it contains a large number of science packages, Anaconda has a large download file (about 531 MB). If you only need some packages, or need to save bandwidth or storage space, you can also use miniconda, a smaller distribution (only including CONDA and python).
