AttributeError：'Cycler'對象沒有屬性'change_key'

我想在Ubuntu上使用import matplotlib。我從源碼重新安裝了matplotlib，因爲我無法使用TkAgg後端。現在我正面臨一個我無法解決的新問題，也無法在任何地方找到解決方案。我正在使用Python 3.5。我有這個錯誤給我看時，我運行一個簡單的導入：AttributeError：'Cycler'對象沒有屬性'change_key'

    cycler_inst.change_key(prop, norm_prop) 
AttributeError: 'Cycler' object has no attribute 'change_key'

我認爲這或許真的從rcsetup.py做循環儀進口，因爲有一個評論它說：

# Don't let the original cycler collide with our validating cycler

所以最初的東西是不是和他們的循環儀碰撞？

我該如何解決這個問題？有什麼建議麼？謝謝！

剛剛檢查了cycler的版本，它已過時。只是

sudo pip3 install --upgrade cycler

或

sudo -H python3 -m pip install --upgrade cycler更新循環儀。

不要忘記你可以使用'--user'而不是'sudo' – Eric
