Проблема с установкой fastai на ubuntu 18.04

Я пытаюсь установить fastai , но ничего не выходит. Я установил pytorch , и он отлично работает. Я пробовал установить с помощью pip3 install fastai . pip3 , потому что у меня есть python2.7 вместе с python3.6. Я обновил инструменты установки, которые не помогли решить проблему.

pip3 install fastai
