pandas head() not reading all rows

[naab]

Hi,

I am reading a csv and applying the def to remove unnecessary data.
If i apply for 174 rows,"dict = (dc_data['Description'].head(174).apply(process_text))" it gives below error.
If i specify 100 rows it works.
Requirements is to apply for all rows.
Any help is appreciated.

Error:

    dict = (ec_data['Description'].head(174).apply(process_text))
