Did you heed my advice and make sure that your script reads and writes the pickle file in binary mode? > file = open("prueba.txt", 'w') The above line can trigger the same error; change "w" to "wb": >>> import pickle >>> class A: pass ... >>> s = pickle.dumps(A()) >>> pickle.loads(s) <__main__.A instance at 0x7f31d088ed88> Seems to work. Now let's simulate the effect of writing in text and reading in binary mode: >>> pickle.loads(s.replace("\n", "\r\n")) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.6/pickle.py", line 1374, in loads return Unpickler(file).load() File "/usr/lib/python2.6/pickle.py", line 858, in load dispatch[key](self) File "/usr/lib/python2.6/pickle.py", line 1069, in load_inst klass = self.find_class(module, name) File "/usr/lib/python2.6/pickle.py", line 1124, in find_class __import__(module) ImportError: No module named __main__ Peter -- http://mail.python.org/mailman/listinfo/python-list
