Everyone is familiar with the compressed file. These compressed file means that we compress one or more files and folders into a file, which is also call archiving.
In addition to archiving, according to the different compression format algorithms, some can even compress the file size to help us better store and transmit these files.
But what if we need to restore the compressed file back to the original file? At this time, we need to decompress according to different compression formats.
Today I want to record how to use Python module zipfile to compress or decompress some fiile as ZIP format.

Glove（Global Vectors for Word Representation）is a paper published by Stanford NLP Group, and it is also an open source pre-trained word embedding model. The Glove that you often see on the Internet now refers to this open source pre-trained model.
Gensim is a Python implementation of the Word2Vec paper proposed by Google in 2013, allowing us to easily train the word vector model using our own corpus via this package.

I have been studying about pointer-generator network lately, and I found a package "pkbar"can let us to use keras style progress bar in our tasks.
In fact, it can be used not only in the code of PyTorch framework but also in any loop.
