Yes that uses a file. I do not want to use a file. I want to pass the object as a string. > If you still don't get it send me the code for the function with a working > code example the calls that function revealing the error. > > I've had a lot of experience with Python and it looks like its the sequence > of functions that causes the problem and not just one Python function call > on its own. I have an object of type Target: (Pdb) type(target) <class 'workitem.Target'> And I pickle it like this: (Pdb) type(pickle.dumps(target)) <type 'str'> And then it looks like this: (Pdb) pickle.dumps(target) "ccopy_reg\n_reconstructor\np0\n(cworkitem\nTarget\np1\nc__builtin__\nobject\np2\nNtp3\nRp4\n(dp5\nS'histologySections'\np6\n(lp7\nsS'registrationTransforms'\np8\nV\np9\nsS'valueMaps'\np10\n(dp11\nsS'targetID'\np12\nVRight-CarotidArtery\np13\nsS'targetInitializer'\np14\ng9\nsS'regions'\np15\n(dp16\nsS'bodySite'\np17\nVRightCarotid\np18\nsS'targetLocalFolderName'\np19\nV21597135/wi-54976537/Right-CarotidArtery\np20\nsS'readingsLocalFileName'\np21\ng9\nsS'probabilityMaps'\np22\n(dp23\nsS'targetPath'\np24\ng9\nsb." And I pass it into a subprocess.Popen call. Then in the program that is called, it comes in as a string: (Pdb) type(args.target) <type 'str'> With the same content: (Pdb) args.target "ccopy_reg\n_reconstructor\np0\n(cworkitem\nTarget\np1\nc__builtin__\nobject\np2\nNtp3\nRp4\n(dp5\nS'histologySections'\np6\n(lp7\nsS'registrationTransforms'\np8\nV\np9\nsS'valueMaps'\np10\n(dp11\nsS'targetID'\np12\nVRight-CarotidArtery\np13\nsS'targetInitializer'\np14\ng9\nsS'regions'\np15\n(dp16\nsS'bodySite'\np17\nVRightCarotid\np18\nsS'targetLocalFolderName'\np19\nV21597135/wi-54976537/Right-CarotidArtery\np20\nsS'readingsLocalFileName'\np21\ng9\nsS'probabilityMaps'\np22\n(dp23\nsS'targetPath'\np24\ng9\nsb." And when I unpickle it I get the error: (Pdb) pickle.loads(args.target) ***ImportError: Import by filename is not supported.
