Xgboost: Des problèmes lors de l'installation sous OSX 10.11.6 ?

Créé le 24 août 2016  ·  37Commentaires  ·  Source: dmlc/xgboost

J'essaie d'installer le wrapper python de xgboost dans OSX 10.11.6 avec python3. Tout d'abord, j'ai fait :

user@MacBook-Pro-de-User-2:~$ brew install gcc --without-multilib

==> make install

Ensuite, lorsque je procède à l'installation de xgboost avec pip3, j'obtiens ce qui suit :

Ensuite, j'ai essayé de construire comme suit:

user@MacBook-Pro-de-User-2:/$ cd xgboost; cp make/config.mk ./config.mk; make -j4
-bash: cd: xgboost: No such file or directory
cp: make/config.mk: No such file or directory
make: *** No targets specified and no makefile found.  Stop.

Une idée de la façon d'installer correctement xgboost ?... il y a un mois, j'ai installé xgboost avec pip3 et je n'ai pas rencontré les problèmes ci-dessus.

Commentaire le plus utile

Succès! ??

J'ai trouvé ça ici :

Le compilateur clang LLVM sur Mac OS X à partir de Xcode ne prend pas en charge le multithread OpenMP. Une alternative consiste à installer homebrew http://brew.sh/ et à brew install g++-5 qui fournit une prise en charge OpenMP multithread.

Gardant cela à l'esprit, j'ai essayé ceci et cela me permet d'installer à partir de pip!

$ brew install gcc<strong i="12">@5</strong>
$ pip install xgboost

Je ne sais pas pourquoi cela fonctionne, mais brew install gcc --without-multilib n'a pas fonctionné.

Je ne peux pas m'empêcher de penser que d'autres utilisateurs tomberont dans ce piège et perdront du temps à essayer de comprendre ce qui ne va pas. Espérons que cette solution de contournement fonctionne pour eux, mais je préférerais voir une routine d'installation plus fiable à partir du package pip 🤞

Apparemment, cela a fonctionné pour OSX:

Cependant, j'aimerais savoir s'il existe un moyen plus simple de l'installer, une suggestion les gars?.

@alonsopg l' pip nécessite gcc-5 ou clang-omp qui peuvent tous deux être installés via brew . Cela a été fait avant la récente mise à jour des instructions. Étant donné que les principaux utilisateurs de Mac OS X utilisent maintenant gcc-6 , je mettrai à jour la prochaine version vers gcc-6, en attendant, veuillez l'installer à partir de github comme vous l'avez compilé

+1 a également rencontré exactement ce problème. Très difficile à comprendre. Notez également que clang-omp n'est plus un package de brassage :

$ brew install clang-omp
Error: No available formula with the name "clang-omp" 
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.

@samuela voulez-vous essayer brew install --with-clang llvm puisque clang-omp est déplacé

@phunterlau Je n'arrive toujours pas à faire fonctionner pip install xgboost sur Mac 10.12.3

Je suis en train:

XGBoostLibraryNotFound: Cannot find XGBoost Libarary in the candicate path, did you install compilers and run build.sh in root path?

J'ai essayé:

$ brew install clang-omp
Error: No available formula with the name "clang-omp" 
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.
$ brew install --with-clang llvm
Warning: llvm: this formula has no --with-clang option so it will be ignored!

Comment sommes-nous censés l'installer à partir de PyPi sur Mac 10.12 ? L'installation à partir de la source n'est pas une solution.

@JoeNyland tu

brew install cmake

Vous pouvez peut-être trouver des idées sur https://github.com/dmlc/xgboost/issues/463 .

@d2Code Merci, mais j'ai toujours le même message d'erreur après brew install cmake :

$ pip install xgboost
...
XGBoostLibraryNotFound: Cannot find XGBoost Libarary in the candicate path, did you install compilers and run build.sh in root path?
...

@JoeNyland Vous pouvez essayer d'installer xgboost à partir de la source, pas par pip.

@d2Code Je sais que je peux installer à partir de la source, mais je dois l' installer à partir de pip. J'essaie de comprendre pourquoi je ne peux pas installer à partir de pip.

@evanuk Merci pour votre suggestion. Malheureusement, je reçois le même message d'erreur qu'avant même avec votre commande ci-dessus

Succès! ??

J'ai trouvé ça ici :

Le compilateur clang LLVM sur Mac OS X à partir de Xcode ne prend pas en charge le multithread OpenMP. Une alternative consiste à installer homebrew http://brew.sh/ et à brew install g++-5 qui fournit une prise en charge OpenMP multithread.

Gardant cela à l'esprit, j'ai essayé ceci et cela me permet d'installer à partir de pip!

$ brew install gcc<strong i="12">@5</strong>
$ pip install xgboost

Je ne sais pas pourquoi cela fonctionne, mais brew install gcc --without-multilib n'a pas fonctionné.

Je ne peux pas m'empêcher de penser que d'autres utilisateurs tomberont dans ce piège et perdront du temps à essayer de comprendre ce qui ne va pas. Espérons que cette solution de contournement fonctionne pour eux, mais je préférerais voir une routine d'installation plus fiable à partir du package pip 🤞

La solution de @JoeNyland a également fonctionné pour moi. Merci!!

merci pour ta solution ! @JoeNyland

Je n'ai pas utilisé de pip pour cela. Il y avait quelques erreurs dans la documentation, mais si vous suivez le lien ci-dessous, il existe des moyens de les résoudre.

J'ai installé gcc7.1.0 avec brew install gcc --without-multilib , puis j'ai cloné xgboost, cd-ed dans le dossier et édité make/config.mk pour avoir

# choice of compiler, by default use system preference.
export CC = gcc-7
export CXX = g++-7 
# export MPICXX = mpicxx

et finalement exécuté cp make/minimum.mk ./config.mk; make -j4

puis cd-ed dans python-package et exécuté sudo python3 setup.py install

Joe Tu es incroyable !

@JoeNyland a rencontré exactement le même problème et votre solution était parfaite. Merci!

@JoeNyland Tu es mon héros ! Parfois, nous avons juste besoin d'une attitude têtue, sinon aucun problème ne pourrait être résolu. Merci!

Ce n'est pas la meilleure solution; ce serait bien de ne pas avoir à dépendre d'une ancienne version de GCC. Mais ça marche pour l'instant au moins

Cependant, je reçois toujours le message d'erreur suivant après l'exécution
$ brew install gcc@5
$ pip installer xgboost

Une idée de pourquoi je reçois ça ? Beaucoup apprécier.

@cacoderquan Hé, pip install xgboost --no-cache-dir .

Si vous voyez toujours l'erreur, pouvez-vous publier le résultat de :

  • python --version
  • pip --version
  • brew info gcc@5

GitHub doit vraiment obtenir des commentaires-tldrs, j'ai passé au crible cela pendant environ 10 minutes, en essayant des déchets aléatoires en cours de route jusqu'à enfin voir le seul commentaire avec plus de 100 likes et pouces levés, etc. ).

Y a-t-il une raison particulière pour laquelle cela ne fonctionne qu'avec gcc@5 et pas avec les gcc gens ont actuellement/typiquement (j'ai gcc 7.2.0 en ce moment) ?

Salut les gars, je n'ai plus d'espoir, mais seulement vous.
J'ai réussi à installer xgboost avec l'aide d'okomarov.

Je n'ai pas trouvé grand chose sur cette erreur. Est-ce que quelqu'un l'a rencontré ?

@cacoderquan J'ai rencontré le même problème que vous et je trouve qu'en fait, le gcc n'est pas lié.
Vous voudrez peut-être aussi le vérifier, mais je parie que votre problème est déjà résolu.
Pour les autres intéressés, le gcc non lié peut résulter de problèmes d'autorisation homebrew .

@JoeNyland merci beaucoup d'avoir sauvé ma journée.

@schen57 Il est documenté à plusieurs endroits que la méthode d'installation pip install xgboost ne fonctionne qu'avec GCC 5.

Veuillez brew install gcc@5 et réessayez l'installation.

https://github.com/dmlc/xgboost/issues/1501#issuecomment -292209578

@alonsopg @phunterlau Je me demande si ce problème peut être clos maintenant ? Cela devient assez important et incontrôlable car il existe une solution au problème d'origine signalé par l'OP. La solution à long terme pour cela est de permettre à la méthode pip install xgboost de fonctionner avec les versions à jour de GCC, mais je pense que cela est mieux géré dans un problème séparé axé spécifiquement sur cela. Qu'est-ce que tu penses?

Oui, d'accord. L'installation de pip a été faite pour la version stable dorée de xgboost, donc une version stable de gcc a été choisie. L'installation de pip utilisera bientôt la version officielle et obtiendra le binaire précompilé comme prévu.

Bien que j'aie installé gcc 5 (avec brew), la version xgboost utilisait toujours la version LLVM de gcc (7 dans mon cas). Pour que la version utilise gcc 5, j'ai fait :

brew install gcc<strong i="6">@5</strong>
env CC=gcc-5 CXX=g++-5 pip install xgboost

et cela a fonctionné pour moi.

Ce qui suit a fonctionné pour moi pour obtenir la dernière version de XGBoost dans Anaconda sans douleur :

  • installer brew (si ce n'est déjà fait)
  • suivez les instructions de @davidread : (merci @davidread !!!)
brew install gcc<strong i="12">@5</strong>
env CC=gcc-5 CXX=g++-5 pip install xgboost

Merci @davidread votre solution a fonctionné après avoir lutté pendant des heures. Don du ciel!!!

En plus de la solution de
env CC=gcc-5 CXX=g++-5 pip3 install xgboost
Cela devrait fonctionner !

Merci @davidread. Après avoir lutté pendant des heures avec gcc-7 et l'option --without-multilib (qui d'ailleurs a été désactivée dans gcc), j'ai encore lutté avec gcc-5 et pip jusqu'à ce que je trouve enfin votre solution ! Merci encore.

@cacoderquan J'ai eu le même problème. Je ne sais pas si vous avez déjà réglé ce problème (je n'ai pas lu tous les commentaires) mais j'ai pu l'installer en exécutant d'abord le fichier build.sh dans le terminal, puis en exécutant setup.py dans le package python dossier.

Merci pour toute l'aide ci-dessus, et en particulier à @davidread , votre méthode a également fonctionné pour moi, comment pouvons-nous nous assurer que nous avons le multi-threading ? Merci d'avance les gars

@okomarov Votre solution pour installer xgboost a fonctionné pour moi. Merci beaucoup !

@davidread Merci beaucoup, votre méthode a fonctionné pour moi !
