TypeError: float() argument must be a string or a number, not 'map'

[Binathi]

When I run the command
python preprocess_embedding.py --embedding glove.840B.300d.txt --dict ./data/qg.tgt.dict --output ./data/qg.tgt.840B.300d.npy

Error:
Unknown word:
Traceback (most recent call last):
File "preprocess_embedding.py", line 76, in
main()
File "preprocess_embedding.py", line 64, in main
embedding[i] = word2embedding[w]
TypeError: float() argument must be a string or a number, not 'map'

Any ideas?

As the code was written in python2, ran the command as follows
python2 preprocess_embedding.py --embedding glove.840B.300d.txt --dict ./data/qg.tgt.dict --output ./data/qg.tgt.840B.300d.npy
