Win10+VS2015+python3.6.8源码编译安装

参考：VS2015编译python 3.6.4源码

参考：解决python “No module named pip”的方法

 

（1）修改build.bat

set platf=x64
set conf=Release

首先编译Release版本，Debug版本在使用pip安装依赖包时会报错。Debug版本可以在最后编译。

 

（2）执行build.bat会在根目录下生成externals文件夹，并用Nuget下载相关的依赖包，但是通常有的依赖包无法完整下载（此后不需要再运行build.bat，其作用是下载依赖包并编译python源码，现在我们手动下载依赖，用VS2015编译），需要手动下载。在get_externals.bat中得知下载网址和依赖包及其版本。VS2015打开项目，根据项目属性中的“包含目录”信息，把下载后的文件放在相应位置。

if "%ORG%"=="" (set ORG=python)

call "%PCBUILD%\find_python.bat" "%PYTHON%"

if "%PYTHON%"=="" (
    where /Q git || echo Python 3.6 could not be found or installed, and git.exe is not on your PATH && exit /B 1
)

echo.Fetching external libraries...

set libraries=
set libraries=%libraries%                                    bzip2-1.0.6
if NOT "%IncludeSSL%"=="false" set libraries=%libraries%     openssl-1.0.2q
set libraries=%libraries%                                    sqlite-3.21.0.0
if NOT "%IncludeTkinter%"=="false" set libraries=%libraries% tcl-core-8.6.6.0
if NOT "%IncludeTkinter%"=="false" set libraries=%libraries% tk-8.6.6.0
if NOT "%IncludeTkinter%"=="false" set libraries=%libraries% tix-8.4.3.6
set libraries=%libraries%                                    xz-5.2.2

for %%e in (%libraries%) do (
    if exist "%EXTERNALS_DIR%\%%e" (
        echo.%%e already exists, skipping.
    ) else if "%PYTHON%"=="" (
        echo.Fetching %%e with git...
        git clone --depth 1 https://github.com/%ORG%/cpython-source-deps --branch %%e "%EXTERNALS_DIR%\%%e"
    ) else (
        echo.Fetching %%e...
        %PYTHON% -E "%PCBUILD%\get_external.py" -O %ORG% -e "%EXTERNALS_DIR%" %%e
    )
)

 

（3）运行python

WIN+R打开命名窗口，cd到python.exe所在目录

C:\Users\zlf>cd C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64>python
Python 3.6.8 (default, Jun 11 2019, 12:22:02) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>>

（4）安装pip

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64>python -m pip install
C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64\python.exe: No module named pip

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64>python -m ensurepip

Successfully installed pip-18.1 setuptools-40.6.2

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64>

（5）添加环境变量PATH

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\Scripts

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8

 

（6）重命名

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64>pip3
Fatal error in launcher: Unable to create process using '"c:\caffe_draft\thirdparty\python-3.6.8\python-3.6.8\pcbuild\amd64\python36.exe"  "C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\Scripts\pip3.exe" '

python.exe 复制一份，重命名为python36.exe

pip.exe不用改，因为已经存在pip3.exe

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64>pip3

You are using pip version 18.1, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

C:\caffe_draft\thirdparty\Python-3.6.8\Python-3.6.8\PCbuild\amd64>

（7）升级pip3（系统中已经存在pyhton2和pip2）

（8）Pycharm中使用python3.6.8

 

 

 

（9）设置pip下载路径，安装常用python依赖包

 

pip freeze > requirements.txt

pip3 install -r requirements.txt

使用国内pip源，这里使用清华大学

pip3 install XXX -i https://pypi.tuna.tsinghua.edu.cn/simple/

pip3 install -r C:\caffe_happynear\caffe-windows-ms\python\requirements.txt  -i https://pypi.tuna.tsinghua.edu.cn/simple

leveldb无法用pip安装，用#注释掉，leveldb数据库可以用lmdb代替。

提示不兼容，python-dateutil>=1.4,<2导致python-dateutil版本太低，matplot和pandas需要其版本大于2.5

由于这里是自己山寨caffe，不是编译caffe，可以没有这个限制。修改requirements.txt如下，重新安装

Cython>=0.19.2
numpy>=1.7.1
scipy>=0.13.2
scikit-image>=0.9.3
matplotlib>=1.3.1
ipython>=3.0.0
h5py>=2.2.0
#leveldb>=0.191
networkx>=1.8.1
nose>=1.3.0
pandas>=0.12.0
#python-dateutil>=1.4,<2
python-dateutil>=2.5
protobuf>=2.5.0
python-gflags>=2.0
pyyaml>=3.10
Pillow>=2.3.0
six>=1.1.0
