This script requires the contents of data.tar. Please refer to the instructions in the section "Download Data" in the readme file.

[chirstinaFan]

We refer to the path of extracted files for data.tar as $DATA_PATH and files for models.tar as $RUN_PATH. Extract vocab.tar to ./vocab directory.

I have done it,But it does not work!

Can you add this print(full_path) before this line:
https://github.com/fartashf/vsepp/blob/master/vocab.py#L77

Then check if the file given by that print statement exists and is readable.
