I wonder if anyone can shed some light on a troublesome intermittent
problem I am having.
Firstly the necessary:
I am running on windows XP, using jython 2.1 and java 1.3.1_03.
A pickled file is created as follows:
self.seq.getMotifs() simply returns a dictionary containing various complex
python objects (which will have been created and used sucessfully)
self.s[self.seqIdx] is a python sequence object.
Intermittently, when I try and reload from this pickle file I get the
Exception occurred during event dispatching:
Traceback (innermost last):
File "pars.py", line 129, in OpenFile
File "D:\program files\jython-2.1\Lib\pickle.py", line 947, in load
File "D:\program files\jython-2.1\Lib\pickle.py", line 567, in load
File "D:\program files\jython-2.1\Lib\pickle.py", line 885, in
TypeError: unhashable type
I have read that this error typically can occur when a pyDictionary or
pyList is inserted into a hashtable. Is this a problem that anyone else is
familiar with, is it a limitation of the jython implementation of pickle?
Any help will be appreciated
