> Hi,
> I was playing with {{pyarrow.csv}} {{read_csv}} and found a rather strange
> behavior that I'm not sure is normal.
> Parsing will fail if the delimiter of the CSV file is a comma and there's a
> blank line after the header (see {{basic_with_blank.csv}} example)
> Example output:
> {{{{Traceback (most recent call last): File "sorrow.py", line 14, in <module>
> table = pa_csv.read_csv(csv) File "pyarrow/_csv.pyx", line 198, in
> pyarrow._csv.read_csv File "pyarrow/error.pxi", line 81, in
> pyarrow.lib.check_status pyarrow.lib.ArrowInvalid: CSV parse error: Expected
> 2 columns, got 1 }}}}
> If I change the CSV delimiter to semicolon, the error disappears and
> everything is fine!
> I'm providing python code and CSV samples which compares with pandas (which
> does not suffer from this).
> Hope this helps, thanks
