Data example from Yelp CSV does not work

[AIG14]

So running download_yelp.sh creates yelp.test.csv and yelp.train.csv, but then running yelp.py how are the sentiment.train and json files created?

Following instructions I get error:
C:\Users\Peter\Downloads\disentangled-style-transfer-vae-master\disentangled-style-transfer-vae-master>python dataset_preproc_scripts\yelp.py TRAIN preprocessed file not found at ./data/yelp/yelp.train.json.

Also instructions will also result in an error No such file or directory: './data/yelp/yelp_w2v_embeddings'
