import-Fehlermeldung, wenn ich testen scikit auf ubuntu12.04

Ich installieren möchte scikit auf ubuntu12.04 und ich folgte den Anweisungen auf die offizielle Dokumentation der Installationund geben Sie den folgenden Befehl in der bash:
sudo apt-get install python-sklearn

next I geben Sie die test-Anweisung
nosetests sklearn --exe

Aber ich habe viele import-Fehler! Ich suchte in google, fand aber wenig nützliche links. Ich bin neu in python und ich möchte lernen, python und maschinellen Lernens durch scikit.Also bitte helft mir, danke.

Nachfolgend werden die Fehlerinformationen, wenn ich nosetests Befehl in der bash.Aufgrund der Längenbegrenzung habe ich gelöscht einige Fehler.

Sind alle erforderlichen Bibliotheken (Schritt 1.1.1 deiner Anleitung) installiert, mit der richtigen version?
Es scheint joblib ist nicht richtig installiert. Das ist merkwürdig, da scikit-learn Schiffe es eigene Kopie der Bibliothek. Sie könnten versuchen import joblib und from sklearn.externals import joblib in einem Python-interpreter?
Ich habe versucht import joblib im python-interpreter, und es sagt Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named joblib
Ich installierte alle Bibliotheken in step1.1.1, außer für die python-numpy-dev, weil wenn ich es installieren des bash-prompts Note,selecting 'python-numpy' instead of 'python-numpy-dev' python-numpy is already the newst version

Überprüfen Sie, ob die python-joblib Paket installiert ist
```
sudo dpkg -l | grep joblib
```
Wenn nichts zurückgegeben wird, versuchen Sie es mit
```
apt-cache search joblib
```
sollte es ein Paket namens python-joblib: installieren Sie mit
```
sudo apt-get install python-joblib
```
ist, und wiederholen Sie.

BEARBEITEN:

Du hast Recht, das Paket ist installiert, aber Python scheint nicht in der Lage, es zu finden (bewiesen durch Ihre import joblib fail). Normalerweise bedeutet dies, dass der Pfad in dem das Paket installiert wurde, ist nicht Teil der Python-Suchpfad.

Was Sie tun können, ist entweder manuell installieren Sie das Modul aus der source und geben Sie den Pfad (das scheint zu sein /usr/lib/python2.7), oder verwenden Sie ein tool wie easy_install oder pip zu tun, dass für Sie.

Gemäß Ihrem guide pip install -U scikit-learn oder easy_install -U scikit-learn sollte den trick tun für Sie, da Ihr die Bibliotheken sind schon da...
- Vielen Dank für Ihre Hilfe. Ich Ihren ersten Befehl und es kehrte so:"ii python-joblib 0.5.4-1-tools für die leichte pipelining in Python"
- Was dpkg -s python-joblib?
- die Ausgabe ist Package: python-joblib Status: install ok installed Priority: optional Section: python Installed-Size: 184 Maintainer: Ubuntu Developers <[email protected]> Architecture: all Source: joblib Version: 0.5.4-1 Depends: python, python-support (>= 0.90.0) Recommends: python-numpy, python-nose, python-simplejson .. Es scheint, dass python-joblib richtig installiert ist. und die Fehler, die ich encounterd auch über die parallele und Speicher
- Ich führen Sie den Befehl easy_install -U scikit-learndann versuche ichnosetests --exe sklearn,die Fehler sind Weg und ich Drucke Ran 1140 tests in 57.793s OK(SKIP=10).Es scheint, dass es ok ist jetzt. Danke!!
- Froh, dass es geholfen hat. Bitte markieren Sie die Antwort, als angenommen, so dass andere Benutzer wissen, wie Sie gelöst wird.
- Ich habe mark als Antwort akzeptiert.Dank
- Btw, brauchen Sie nicht manuell zu installieren joblib, es ist enthalten in sklearn.
- Ich habe noch nie versucht das tool, also ich wusste das nicht, danke. Wie auch immer, ich dachte, es wäre gut, um zu überprüfen, ob es installiert wurde 🙂
