My data format is: userID<space>movieID<space>rating

Please tell me the correct format for the data to run LogisticRegression with Husky.

Thank you so much!

The format is one of:

// format
// type: string
// info: the data format of input file: libsvm/tsv

You entered string. I have no idea what libsvm is but tsv stands for Tab Separated Values. Maybe try adding tabs in the place of <space>?
