Python - Sklearn - ImportError

Question

Ich habe Probleme mit dem Import von Sklearn.

Ich habe das Paket durch Pip installiert, aber Python kann die Bibliothek nicht importieren. Ich benutze Python 2.7 in einer Windows 10-Umgebung.

from sklearn.tree import DecisionTreeClassifier, export_graphviz 

Der Fehler ich erhalte, ist die folgende:

Traceback (most recent call last): 
    File "classification.py", line 7, in <module> 
    from sklearn.tree import DecisionTreeClassifier, export_graphviz 
    File "C:\Python27\lib\site-packages\sklearn\__init__.py", line 56, in <module> 
    from . import __check_build 
ImportError: cannot import name __check_build 

Ich habe gelesen, dass jemand Lösung durch die Installation SciPy (scipy-0.19.1.tar.gz) finden, aber wenn ich versuche, über die Installation pip die prompte Rückkehr ich diese Meldung:

C:\Python27\Scripts>pip install scipy 
Collecting scipy 
    Using cached scipy-0.19.1.tar.gz

    Note: if you need reliable uninstall behavior, then install 
    with pip instead of using `setup.py install`: 

     - `pip install .`  (from a git repo or downloaded source 
           release) 
     - `pip install scipy` (last SciPy release on PyPI)

Danke für die Hilfe,

Answer 1

Download von here. Dann ändere den Pfad zur Datei mit cd in cmd. Danach tun Sie pip install filename.whl. Verwenden Sie natürlich den tatsächlichen Dateinamen.

Answer 2

Öffnen Sie Ihr Terminal (cmd) und versuchen Sie diese, bevor Sie versuchen, den Sklearn zu importieren.

pip install -U scikit-learn 

oder

conda install scikit-learn 

Auch stellen Sie sicher, dass Sie waren numpy und scipy: nach der Installation von scipy

Starten Sie den Python-Shell:

pip install numpy 
pip install scipy 

Gruppe 1 TRY!

Versuchen Sie, diese 2:

Installieren numpy + mkl Paket von link und nach erfolgreicher Installation starten Sie den Python.

die whl Datei verwenden zu installieren: pip install some-package.whl

Wenn nichts funktioniert ......

AUSPROBIEREN 3:

Set Systempfad Variable für Python Up und der Umgebungsvariablen PYTHONPATH

Systemvariablen: in C: \ Python34 in Pfad

Benutzervariablen: add neu: (Name) PYTHONPATH (Wert) C: \ Python34 \ Lib \ Site-Pakete;

Finale, was zu versuchen:

anaconda Installieren von here

und dann laufen: conda install scikit-learn
