Hi all, I have this error when I try to use Manager() from python multiprocessing library. (Just start QGIS open Python console and execute the two following lines)
>>> import multiprocessing >>> mgr = multiprocessing.Manager() Traceback (most recent call last): File "<input>", line 1, in <module> File "C:\DEV\osgeo4w_dev\apps\Python27\lib\multiprocessing\__init__.py", line 99, in Manager m.start() File "C:\DEV\osgeo4w_dev\apps\Python27\lib\multiprocessing\managers.py", line 524, in start self._process.start() File "C:\DEV\osgeo4w_dev\apps\Python27\lib\multiprocessing\process.py", line 130, in start self._popen = Popen(self) File "C:\DEV\osgeo4w_dev\apps\Python27\lib\multiprocessing\forking.py", line 252, in __init__ cmd = get_command_line() + [rhandle] File "C:\DEV\osgeo4w_dev\apps\Python27\lib\multiprocessing\forking.py", line 339, in get_command_line if process.current_process()._identity==() and is_forking(sys.argv): AttributeError: 'module' object has no attribute 'argv' >>> It happens in both 1.8 and 1.9 dev version on Windows X. Of course everything is ok using QGIS on Linux!... :P It seems something related to the main Python/QGis process startup and the way the library tries to start a new process.... but I can't figure out any workaround. Any idea? Saverio
