[Pytables-users] Problems with Converting Python Int to C Long

[Jacob B. <jac...@gm...>]

Hello PyTables Users,

I have a concern with a very strange error that references that my python
ints cannot be converted to C longs when trying to run Table.append(rows).
My python integers are definitely not big, at most they would probably be
around 3 billion in size, which shouldn't be any problem for conversion to
C long.

This is the error that I am receiving...

Exception in thread bookthread:
Traceback (most recent call last):
  File "C:\Python27\lib\threading.py", line 551, in __bootstrap_inner
    self.run()

    BookDataWrapper.acceptDict()

    tableD.append(dataArray)
  File "C:\Python27\lib\site-packages\tables\table.py", line 2076, in append
    "rows parameter cannot be converted into a recarray object compliant
with table '%s'. The error was: <%s>" % (str(self), exc)
ValueError: rows parameter cannot be converted into a recarray object
compliant with table '/t301491615959191971 (Table(0,), shuffle, blosc(3))
'Instrument''. The error was: <Python int too large to convert to C long>

Thanks,
Jacob
