Я занимаюсь разработкой с Python для Linux и никогда не видел подобной проблемы с Windows. Я использую библиотеку multiprocessing
для ускорения вычислений, которая очень хорошо работает для меня в Linux.
Однако в Windows дела идут не так гладко:

Я тестирую на Python 2.6 и 2.7 на Windows 7 и получаю эту ошибку снова и снова. Кто-нибудь знает, что это значит?
