Question

Bob使用Party.joins(:name, :expired_names).to_sql => "SELECT \"parties\".* FROM \"parties\" INNER JOIN \"party_names\" ON \"party_names\".\"party_id\" = \"parties\".\"id\" INNER JOIN \"expired_names\" ON \"expired_names\".\"party_id\" = \"parties\".\"id\""向其用户推荐其install个包，但我不想使用conda。如何从源代码安装它？

Answer 1

解释

首先，使用conda来安装Bob更容易，并且是支持安装Bob的方法。在继续之前，请再次考虑使用conda来安装Bob。 Bob是用C ++和Python混合编写的，并链接到许多不同的C / C ++库，Conda是一个与语言无关的二进制包管理器，可以处理所有这些。

如果要从源安装Bob，首先需要手动安装其依赖项。每个包的依赖关系列在每个Bob包的conda配方中。从其conda配方中，您必须安装（如果存在）requirements:build，requirements:host，requirements:run和test:requires。这些包是conda包而不是pip包;其中一些可能是pip包（名称可能不同），其中一些可能只是一个C / C ++库，您应该使用系统的包管理器（或从源代码）安装。

例如，bob.extension的conda配方是here：

requirements:
  host:
    - python {{ python }}
    - setuptools {{ setuptools }}
  run:
    - python
    - setuptools
    - click
    - click-plugins

test:
  requires:
    - bob-devel {{ bob_devel }}.*
    - nose
    - coverage
    - sphinx
    - sphinx_rtd_theme
    - boost
    - cmake
    - pkg-config
    - freetype
    - libblitz
    - numpy
    - {{ compiler('c') }}
    - {{ compiler('cxx') }}
    - bob.buildout

解析此配方意味着您需要安装：首先是系统的包管理器boost，cmake，pkg-config，freetype，libblitz，C and C++ compilers，可能numpy然后使用pip安装click，click-plugins，nose，coverage，sphinx，sphinx_rtd_theme和bob.buildout。（您还可以查看Bob软件包的requirements.txt和test-requirements.txt以查找依赖项的pip包名称，但可能无法更新以匹配其conda配方）。 bob-devel是一个conda元数据包，在不使用conda时不需要安装。

这将设置您的环境以准备编译（如果需要），安装和测试bob.extension。设置环境后，您可以使用pip来安装bob.extension：

pip install bob.extension

然后，您需要按Bob包依赖项的顺序安装下一个Bob包。正如您所看到的，这可能非常耗时，但这是实现它的唯一方法，可以在Bob的软件包开发及其依赖关系发生变化时起作用。

说明

这些说明将帮助您安装大多数包含难以安装的C ++代码的Bob软件包。安装这些软件包后，您很可能可以使用pip安装其余的Bob软件包。

依赖关系

您需要先使用系统的软件包管理器安装Bob软件包依赖项。

安装依赖项后，您可以使用pip从源代码安装。

可以使用pip全局或私有安装软件包 virtualenv，如果这是您喜欢Python工作环境的方式。您需要手动安装所需的所有软件包（直接或间接），因为pip / setuptools目前无法连贯地安装Python 相互依赖的软件包用于构建，例如很多情况包。

例如，在新创建的虚拟中安装bob.io.image 环境，这是要执行的命令序列：

$ pip install numpy
$ pip install bob.extension
$ pip install bob.blitz
$ pip install bob.core
$ pip install bob.io.base
$ pip install bob.io.image

每个pip命令必须单独执行，尊重包间依赖性。

以下不按预期工作：

$ #Do not do this:
$ pip install numpy bob.io.image

核心包的依赖性可归纳为7层和以下脚本可用于使用pip安装所有核心软件包：

$ bash pip_install_bob.sh
-------------------------
#!/bin/bash
set -e

get_layer() {
case $1 in
 1)
   packages=("bob.extension")
   ;;
 2)
   packages=("bob.blitz")
   ;;
 3)
   packages=("bob.core" "bob.ip.draw")
   ;;
 4)
   packages=("bob.io.base" "bob.sp" "bob.math")
   ;;
 5)
   packages=("bob.ap" "bob.measure" "bob.db.base" "bob.io.image" "bob.io.video" "bob.io.matlab" "bob.ip.base" "bob.ip.color" "bob.ip.gabor" "bob.learn.activation" "bob.learn.libsvm" "bob.learn.boosting")
   ;;
 6)
   packages=("bob.io.audio" "bob.learn.linear" "bob.learn.mlp" "bob.db.wine" "bob.db.mnist" "bob.db.atnt" "bob.ip.flandmark" "bob.ip.facedetect" "bob.ip.optflow.hornschunck" "bob.ip.optflow.liu")
   ;;
 7)
   packages=("bob.learn.em" "bob.db.iris")
   ;;
esac
}

for layer in `seq 1 7`;
do
 get_layer ${layer}
 for pkg in "${packages[@]}";
 do
   pip install $pkg
 done
done
