兩種形式的Jupyter筆記本的問題

最近，我在jupyter筆記本上安裝了第二個python，以便我可以在需要時使用Python2或3。但是，在安裝了三個之後，我在之前的python2筆記本中遇到了matplotlib，scipy和numpy的問題。兩種形式的Jupyter筆記本的問題

我從這個得到的是看進口時python2不再指向正確的目錄。我如何去設置路徑到正確的目錄？

感謝先進！

這是一個非常普遍的問題，不同的python用例需要不同的安裝。爲了避免串擾，您可以使用virtualenv來分隔您的安裝。

我實際上卸載了一切，並重新安裝了一切，它似乎保留了兩個版本並鏈接到正確的導入...所以一切都好！ –

我完全卸載了所有內容，然後重新安裝並更正了路徑。
