kann nicht installiert numpy mit setup.py

Question

Ich bin auf Python 2.7 und ich versuche, die NLTK Teil der Rede Tagger zu verwenden, die diesen Fehler erzeugt, weil ich nicht numpy installiert haben:

> Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/Library/Python/2.7/site-packages/nltk/tag/__init__.py", line 99, in pos_tag 
    tagger = load(_POS_TAGGER) 
    File "/Library/Python/2.7/site-packages/nltk/data.py", line 605, in load 
    resource_val = pickle.load(_open(resource_url)) 
ImportError: No module named numpy.core.multiarray 

So lade ich numpy 1.7.0 von here, hat eine cD in meinem Download-Ordner und python haben setup.py installieren und habe diesen Fehler:

ich pip installieren dann versuchte es mit sudo zu installieren -U numpy und bekam den gleichen Fehler "kann ein einfaches C-Programm nicht verbinden". Ich kann nicht herausfinden, was hier vor sich geht. Ist die numpy Version mit Python 2.7 oder NLTK inkompatibel?

Answer 1

Das Modul hängt von einer funktionierenden C-Kette ab. Es hängt von Ihrem System ab, wie Sie es installieren, Google wird in diesem Fall helfen.

Sie können es sehen für gcc suchen:

sh: gcc-4.2: command not found 

Auf Debian-basierten Linux würden Sie das und die Python-Header mit (bearbeitet pro Kommentar) installieren:

sudo apt-get install build-essential python-dev 

Answer 2

Vielleicht nicht, was Sie brauchen, aber wenn Sie Probleme mit der Installation von numpy haben, empfehle ich "Pyzo". Es ist eine Python-Distribution, die mit einem sehr interessanten Satz von Paketen einhergeht, unter denen sich numpy befindet. www.pyzo.org

Answer 3

Sie müssen gcc installieren.

Auf CentOS:

sudo yum install gcc 

Versuchen numpy neu zu installieren, wenn Sie sehen den folgenden Fehler:

Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-root/numpy 

Run:

sudo yum install python-devel 

Answer 4

Kürzlich hatte ich das schon gesehen zusammen mit:

Klirren: Fehler: unbekannt Argument: '-mno-verschmolzenen madd' [-Wunused-Befehlszeile-Argument-hard-Fehler-in-Zukunft]

Siehe hier zu beheben:

clang error: unknown argument: '-mno-fused-madd' (python package installation failure)

Answer 5

Ich lief auf den gleichen Fehler und behob es durch Aktualisierung von Pip.

pip install --upgrade pip 

Hoffe, dass es hilft.
