Hi!
Sorry for not writing to you earlier. Lets try it this way. The root problem is
following. I am using Pytables version 2.0.3. I found out that when I use
readWhere function I get the error:
File "C:\Python24\Lib\site-packages\tables\table.py", line 1276, in readWhere
splitted = self._splitCondition(condition, condvars)
File "C:\Python24\Lib\site-packages\tables\table.py", line 1091, in _splitCond
ition
splitted = split_condition(condition, typemap, indexedcols, copycols)
File "C:\Python24\Lib\site-packages\tables\conditions.py", line 116, in split_
condition
expr = stringToExpression(condition, typemap, {})
File "C:\Python24\Lib\site-packages\tables\numexpr\compiler.py", line 194, in
stringToExpression
old_ctx = expressions._context.ctx
AttributeError: 'thread._local' object has no attribute 'ctx'
Now, I know you fixed this problem by posting a new SVN version. The question
is how can I include these patches when I come to an error without installing
the whole PytTables package. I want o bypass the compiling stuff. Is this
possible?
Manny thanks!
Cheers, Dragan.
