Hello
Im newbie in pytables and I have a question regarding to an error
message. I writing a program which basically read a text file to a
pytable and then I want to modify one field in the table according to
a condition related to another field. the program is very simple and
I'm getting the following error:
File "D:\python\prod_tests\src\test_receivers.py", line 54, in <module>
check_receivers(path_r,1)
File "D:\python\prod_tests\src\test_receivers.py", line 45, in check_receivers
for row in ro_detector.where('completo <= 20000'):
File "C:\Python26\lib\site-packages\tables\table.py", line 1210, in where
return self._where(condition, condvars, start, stop, step)
File "C:\Python26\lib\site-packages\tables\table.py", line 1226, in _where
condvars = self._requiredExprVars(condition, condvars, depth=3)
File "C:\Python26\lib\site-packages\tables\table.py", line 977, in
_requiredExprVars
user_locals = user_frame.f_locals
File "C:\Python26\lib\site-packages\psyco\support.py", line 124, in
__getattr__
raise AttributeError, ("local variables of functions run by Psyco "
AttributeError: local variables of functions run by Psyco cannot be
accessed in any way, sorry
Closing remaining open files: temp.h5... done
I got the same error in Windows xp as well as Ubuntu 10.4.
Could you please help me with that?
Regards
