Anyone who wants to develop python, especially django, will have an experience: Entering the python interaction mode (directly executing the python Press enter) or entering the django-shell debugging function, and then modifying the source code, exit the interaction mode or djangoshell, and re-enter those modules in one-to-one import... What is the problem? It's a waste of time. Why don't I modify the source code auto reload like the web framework?I spent more than two weeks doing this.

file. This dataset has 4 columns per row, corresponding to the user ID, item ID, score, and timestamp. Because my machine is broken, in the following example, I only used the first 100 data. So if you use all the data, the predictions will be different from mine.First you need to make sure that you have Hadoop and spark installed (not less than 1.6) and that you have set up environment variables. Generally we are studying in Ipython notebook (Jupyter

A powerful library:Turn from: Public numberOne of the best places in Python is a large number of third-party libraries, with a wide range of amazing coverage. One drawback of the Python library is that the global installation is done by default. In order for each project to have a separate environment, you need to use the tool virtualenv, and then work with the Package management tool PIP and virtualenv.Although you can turn to Google or Baidu, but also to do so, according to personal knowledge
