Need help for applying your code on my own dataset

[wanghao14]

Hi Devendra, thanks for open sourcing this great project! I want to apply your code on my own Chinese dataset, but I am confused on how to process my dataset to get files like Pre-tokenized evidence passages and their titles and Wikipedia evidence passages from DPR paper you provided for open-domain QA tasks. Could you give me some advice to build them? Thanks in advance.
