Hi,
I created a PyTables file containing circa 15000 groups, where in each of
these groups, there is one single table, defined using the following class:
class *SimpleScheme*(tables.IsDescription):
value = tables.Float32Col(pos = 0, dflt = numpy.NaN)
Each such a table has about 1500 rows in it.
The table creation phase was successful, and I can verify that by opening
ViTables and seeing the values for each one of the tables.
The problem is that when I try to read ONE FLOAT from each one of the tables
(meaning, a total of 15000 floats), I get an error after about a while:
Traceback (most recent call last):
File "C:\Documents and Settings\pytables -- e.py", line 179, in <module>
ReadFile2()
File "C:\Documents and Settings\pytables -- e.py", line 89, in ReadFile2
listItems.append(table[0][0])
File "C:\Python26\lib\site-packages\tables\table.py", line 1714, in
__getitem__
return self.read(start, stop, step)[0]
File "C:\Python26\lib\site-packages\tables\table.py", line 1583, in read
arr = self._read(start, stop, step, field)
File "C:\Python26\lib\site-packages\tables\table.py", line 1536, in _read
self._read_records(start, stop-start, result)
File "tableExtension.pyx", line 565, in
tables.tableExtension.Table._read_records
HDF5ExtError: Problems reading records.
>>>
Can anybody tell me what is the problem, and how to fix it? I can send the
file if necessary (it has a size of 22MB). Thanks.
