I've encountered a strange issue where the number of documents that I'm feeding into tf-idf is 2306041, but when I apply np.shape to the output, the number of rows is 2306047. What could be the cause of the problem?

Not sure why but issue is resolved if I convert the dataframe column to list

Could it be a sparse dataframe, and thus related to pandas-dev/pandas#14167?
