Xgboost: Problemas ao instalar no OSX 10.11.6?

Criado em 24 ago. 2016  ·  37Comentários  ·  Fonte: dmlc/xgboost

Estou tentando instalar o wrapper python do xgboost no OSX 10.11.6 com python3. Em primeiro lugar, eu fiz:

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

==> make bootstrap

==> make install
🍺  /usr/local/Cellar/gcc/6.2.0: 1,357 files, 242.5M, built in 69 minutes 18 seconds

Então, quando prossigo para a instalação do xgboost com pip3, obtenho o seguinte:

Então tentei construí-lo conforme a documentação afirma :

Então, tentei construir da seguinte maneira:

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.

Alguma ideia de como instalar o xgboost corretamente? ... há um mês instalei o xgboost com o pip3 e não enfrentei os problemas acima.

Comentários muito úteis

Sucesso! 🎉

Eu encontrei isso aqui :

O compilador clang LLVM no Mac OS X da Xcode não oferece suporte a multi-thread OpenMP. Uma escolha alternativa é instalar o homebrew http://brew.sh/ e o brew install g ++ - 5 que fornece suporte OpenMP multi-thread.

Tendo isso em mente, tentei fazer isso e me permite instalar a partir do pip!

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

Não tenho ideia de por que isso funciona, mas brew install gcc --without-multilib não.

Não posso deixar de pensar que outros usuários vão cair nessa armadilha e perder tempo tentando descobrir o que realmente está errado. Espero que esta solução alternativa funcione para eles, mas eu prefiro ver uma rotina de instalação mais confiável do pacote pip 🤞

Aparentemente, isso funcionou para OSX:

Porém, gostaria de saber se existe uma maneira mais fácil de instalar, alguma sugestão pessoal ?.

@alonsopg a instalação atual de pip requer gcc-5 ou clang-omp que podem ser instalados através de brew . Isso foi feito antes da recente atualização das instruções. Como os principais usuários do Mac OS X agora usam gcc-6 , atualizarei a próxima versão para gcc-6, enquanto isso, instale do github conforme você compilou

1 também deparei exatamente com esse problema. Muito complicado de descobrir. Observe também que o clang-omp não é mais um pacote de cerveja:

$ 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 , você quer tentar brew install --with-clang llvm porque clang-omp foi movido

@phunterlau Ainda não consigo fazer pip install xgboost funcionar no Mac 10.12.3

Estou entendendo:

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

Eu tentei:

$ 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

Como devemos instalar isso de PyPi no Mac 10.12? A instalação da fonte não é uma solução.

@JoeNyland talvez você precise:

brew install cmake

Talvez você possa obter algumas ideias em https://github.com/dmlc/xgboost/issues/463 .

@ d2Code Obrigado, mas continuo 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 Você pode tentar instalar o xgboost a partir do código-fonte, não pelo pip.

@ d2Code Eu sei que posso instalar a partir da fonte, mas preciso instalar a partir do pip. Estou tentando descobrir por que não consigo instalar a partir do pip.

@evanuk Obrigado pela sua sugestão. Infelizmente estou recebendo a mesma mensagem de erro de antes, mesmo com o seu comando acima 😕

Sucesso! 🎉

Eu encontrei isso aqui :

O compilador clang LLVM no Mac OS X da Xcode não oferece suporte a multi-thread OpenMP. Uma escolha alternativa é instalar o homebrew http://brew.sh/ e o brew install g ++ - 5 que fornece suporte OpenMP multi-thread.

Tendo isso em mente, tentei fazer isso e me permite instalar a partir do pip!

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

Não tenho ideia de por que isso funciona, mas brew install gcc --without-multilib não.

Não posso deixar de pensar que outros usuários vão cair nessa armadilha e perder tempo tentando descobrir o que realmente está errado. Espero que esta solução alternativa funcione para eles, mas eu prefiro ver uma rotina de instalação mais confiável do pacote pip 🤞

A solução de @JoeNyland também funcionou para mim. Obrigado!!

obrigado pela sua solução! @JoeNyland

Eu não usei pip para isso. Ocorreram alguns erros na documentação, mas se você seguir o link abaixo, existem algumas maneiras de resolver isso.

Eu instalei gcc7.1.0 com brew install gcc --without-multilib , em seguida, clonado xgboost, cd-ed na pasta e editei make/config.mk para ter

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

e finalmente executou cp make/minimum.mk ./config.mk; make -j4

então cd-ed em python-package e executou sudo python3 setup.py install

Joe Você é incrível!

@JoeNyland encontrou exatamente o mesmo problema e sua solução foi perfeita. obrigada!

@JoeNyland Você é meu herói! Às vezes, só precisamos da atitude teimosa, caso contrário, nenhum problema poderia ser resolvido. Obrigado!

Não é a melhor solução; seria bom não ter que depender de uma versão mais antiga do GCC. Mas funciona por agora, pelo menos 🙂

No entanto, ainda recebo a seguinte mensagem de erro depois de executar
$ brew install gcc @ 5
$ pip install xgboost

Alguma ideia de por que estou recebendo isso? Muito obrigado.

@cacoderquan Ei, ainda não sei por que você está vendo esse problema. Você já tentou pip install xgboost --no-cache-dir .

Se você ainda vir o erro, pode postar o resultado de:

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

O GitHub realmente precisa de comentários, eu examinei isso por cerca de 10 minutos, tentando lixo aleatório ao longo do caminho até finalmente ver o único comentário com mais de 100 curtidas e polegares para cima e etc (e funcionou para mim também! Então, yay! )

Existe um motivo específico para que ele funcione apenas com gcc@5 e não com qualquer gcc pessoas atualmente / normalmente têm (eu tenho gcc 7.2.0 no momento)?

Oi pessoal, não tenho mais esperança, só vocês.
Consegui instalar o xgboost com a ajuda de okomarov.

Não encontrei muito sobre este erro. Alguém o encontrou?

@cacoderquan Eu encontrei um problema semelhante ao de você e descobri que na verdade o gcc não está vinculado.
Você pode querer verificar também, mas aposto que seu problema já foi resolvido.
Para outros interessados, o gcc desvinculado pode resultar de problemas de permissão de homebrew .

@JoeNyland muito obrigado por salvar meu dia.

@cacoderquan Tenho problemas semelhantes ao tentar instalar o pip xgboost
Minha versão do gcc é

Tentei instalar o gcc muitas vezes, mas nada funciona. Sempre que experimentei pip install xgboost, os seguintes erros aparecem:

PLZ HELP

@ schen57 Está documentado em vários lugares que o método de instalação pip install xgboost só funciona com o GCC 5.

brew install gcc@5 e tente instalar novamente.

https://github.com/dmlc/xgboost/blob/master/python-package/README.rst
https://xgboost.readthedocs.io/en/latest/build.html#building -on-macos
https://github.com/dmlc/xgboost/issues/1501#issuecomment -292209578

@alonsopg @phunterlau Gostaria de saber se este problema pode ser encerrado agora? Está ficando muito grande e fora de controle, pois há uma solução para o problema original relatado pelo OP. A correção de longo prazo para isso é permitir que o método pip install xgboost funcione com versões atualizadas do GCC, mas acho que é melhor lidar com isso em uma questão separada focada especificamente nisso. O que você acha?

Sim combinado. A instalação do pip foi feita para a versão estável dourada do xgboost, portanto, uma versão estável do gcc foi escolhida. A instalação do pip em breve usará a versão oficial e obterá o binário pré-compilado conforme planejado.

Embora eu tenha instalado o gcc 5 (com brew), o xgboost build ainda usa a versão LLVM do gcc (7 no meu caso). Para obter a compilação para usar o gcc 5, fiz:

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

e isso funcionou para mim.

O seguinte funcionou para mim para obter a versão mais recente do XGBoost no Anaconda sem dor:

  • instale brew (se ainda não estiver lá)
  • siga as instruções de @davidread : (obrigado @davidread !!!)
brew install gcc<strong i="12">@5</strong>
env CC=gcc-5 CXX=g++-5 pip install xgboost

Obrigado @davidread, sua solução funcionou depois de lutar por horas. Godsend !!!

Além da solução de @davidread , se pip install não funcionar para você, tente a segunda linha como:
env CC=gcc-5 CXX=g++-5 pip3 install xgboost
Isso deve funcionar!

Obrigado @davidread. Depois de lutar por horas com o gcc-7 e a opção --without-multilib (que por sinal foi desabilitada no gcc), eu me esforcei um pouco mais com o gcc-5 e o pip até que finalmente encontrei sua solução! Obrigado novamente.

@cacoderquan Eu tive o mesmo problema. Não sei se você já classificou isso (não li todos os comentários), mas consegui instalar executando primeiro o arquivo build.sh no terminal e, em seguida, executando setup.py no pacote python pasta.

Obrigado por toda a ajuda acima, e especialmente para @davidread , seu método funcionou para mim também, como podemos ter certeza de que temos multi-threading? Obrigado antecipadamente pessoal

@okomarov Sua solução para instalar o xgboost funcionou para mim. Muitíssimo obrigado!

@davidread Muito obrigado, seu método funcionou para mim!
