我正在使用Jupyter Notebook，我想導入名爲bluepyopt的外部工具箱。由於它目前只在Python 2.7中運行，因此我按照here的描述設置了一個Python 2.7內核。所以我可以在Jupyter Notebook中將內核更改爲python 2。 如果我想導入使用Python：成功安裝模塊，但無法通過導入獲得
import bluepyopt as bpop
我得到的錯誤
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-1-83e46e18aae9> in <module>()
3
4 # to create electrical cell models
----> 5 import bluepyopt as bpop
6 import bluepyopt.ephys as ephys
7
ModuleNotFoundError: No module named 'bluepyopt'
我安裝bluepyopt我通常
!pip install bluepyopt
安裝模塊的方式，模塊這也給了我一個不尋常的超級loooooong輸出。我不知道這裏重要的是什麼，所以我會把它全部公佈一下。這隻發生在python 2.7中，但在python 3中一切正常！任何想法爲什麼它是這樣的？
