Python: installer un module avec succès mais il n'est pas disponible via l'import

J'utilise Jupyter Notebook et je veux importer une boîte à outils externe appelée bluepyopt. Comme il ne fonctionne actuellement qu'en Python 2.7, j'ai mis en place un noyau Python 2.7 comme décrit here. Je peux donc changer mon noyau en python 2 dans Jupyter Notebook. Si je veux importer le module en utilisantPython: installer un module avec succès mais il n'est pas disponible via l'import

import bluepyopt as bpop

Je reçois l'erreur

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'

installer bluepyopt la façon dont j'installe habituellement des modules avec

!pip install bluepyopt

Cela donne aussi me une sortie super loooooong extraordinaire. Je ne sais pas ce qui est important ici, alors je vais tout afficher pour être sûr. Cela ne se produit que dans Python 2.7, mais en python 3 tout fonctionne bien! Une idée de pourquoi c'est comme ça?

double possible de [Erreur lors de l'installation lxml par pip: Microsoft Visual 14.0 C++ est requis] (https://stackoverflow.com/questions/38949519/error-while-installing-lxml-through-pip-microsoft-visual-c-14-0-is-required) – phd

Comme je peux voir le module est pas correctement installé et la dépendance donnant pour Microsoft Visual C++ 14.0.

Essayez d'installer Microsoft Visual C++ construire des outils de ce lien http://landinghub.visualstudio.com/visual-cpp-build-tools

Ensuite, essayez d'installer le module à l'aide pip à nouveau

pip install bluepyopt

Merci pour votre commentaire! J'ai installé Microsoft Visual C++ Redistributable pour Visual Studio 2017, qui n'a rien changé. –

N'installez pas l'outil de création Visual Studio, installez les outils de construction Visual C++ 2015 –

Cela a résolu le problème pour mon noyau python 3! Agréable. Mais si je l'installe dans mon noyau python 2.7, j'obtiens la même sortie et l'erreur d'importation. Bizarre. –
