I am trying to read the a bin file. It has millions of lines of a word followed by space separated numbers.
So, far in Python I havent been able to get a line printed, it either gives gibberish or wrong output.
with open('GoogleNews-vectors-negative300.bin', mode='rb') as file: # b is important -> binary
for line in file.readline():
print(line)
How should I read a binary file line by line?
Binary files tend to not be line-oriented. They also will show gibberish when printed. So your code is working, but your expectations are wrong.
What's your ultimate goal? If it's to have usable word-vectors, you probably want to use some pre-existing Word2Vec library, such as gensim in Python.
In such a library, you can also view the source-code for reading the .bin word-vectors format, as a model to learn from, if for some reason you really do need to write your own reading code. For example, here's the gensim source code that reads word-vector files in the format written by the original word2vec.c code from Google:
(It's more often used from the KeyedVectors.load_word2vec_format() public API method.)
