You can simply download the vocabularies from here:
http://www.cs.toronto.edu/~faghri/vsepp/vocab.tar

Please refer to the instructions in the section "Download Data" in the readme file.

I want to know when I use my data,how to build our vocab.pkl?

[fartashf]

You would need to modify and run vocab.py. Look at the how supported datasets are handled in that file.
