In some cases, the pandas.parser.CParserError generated when reading a file written by pandas.to_csv(), it might be because there is a carriage return (‘\r’) in a column names, in which case to_csv() will actually write the subsequent column names into the first column of the data frame, it will cause a difference between the number of columns in the first X rows. This difference is one cause of the CParserError .
Also, the Error tokenizing data may arise when you’re using separator (for eg. comma ‘,’) as a delimiter and you have more separator than expected (more fields in the error row than defined in the header). So you need to either remove the additional field or remove the extra separator if it’s there by mistake. The better solution is to investigate the offending file and to fix it manually so you don’t need to skip the error lines.
