Summary: Pull Request resolved: facebookresearch#777 TSVDataSource documentation for delimiter param says Change to "," for csv, but csv files often have quoted fields and TSVDataSource does not support quoted fields. We cannot blindly force all fields starting with quotes to be treated as quoted fields, because it drastically changes the behavior: unclosed quoted fields will merge with the next row, swallowing \n characters until we find the closing quote. Some data sets might contain unclosed fields with quotes and rely on the current behavior. This diff adds a parameter to the TSVDataSource config that allows users to specify whether they want quoted fields. The default is False, which is the current behavior.
