Parameters
----------
fname: string
Path to file containing embedding
format: string
Format of the embedding. Possible values are:
'word2vec_bin', 'word2vec', 'glove', 'dict'
normalize: bool, default: True
If true will normalize all vector to unit length
clean_words: bool, default: True
If true will only keep alphanumeric characters and "_", "-"
Warning: shouldn't be applied to embeddings with non-ascii characters
load_kwargs:
Additional parameters passed to load function. Mostly useful for 'glove' format where you
should pass vocab_size and dim.
