Detailed tutorial on installing Anaconda3 on Ubuntu 18.04

Anaconda refers to an open source Python distribution that includes more than 180 scientific packages such as conda, Python, and their dependencies. Because it contains a large number of scientific packages, the download file of Anaconda is relatively large (about 531 MB). If you only need certain packages, or need to save bandwidth or storage space, you can also use Miniconda, a smaller distribution (containing only conda and Python).
