numpy-1.11.3+mkl-cp27-cp27m-win_amd64.whl
scipy-0.19.1-cp27-cp27m-win_amd64.whl 经检验：64位的不匹配 查看：显示当前版本信息 >>>import pip >>> print(pip.pep425tags.get_supported()) ===>>(cp27,cp27m,win32) 故选择安装：numpy-1.13.1+mkl-cp27-cp27m-win32.whl、matplotlib-1.5.3-cp27-cp27m-win32.whl、 scipy-0.19.1-cp27-cp27m-win32.whl和scikit_learn-0.19.0-cp27-cp27m-win32.whl 一、安装顺序及过程：
1、安装wheel
===D:\软件\python\setup\Scripts>>pip install wheel 2、安装numpy-1.13.1+mkl-cp27-cp27m-win32.whl ===D:\软件\python\setup\Scripts>>pip install D:\软件\Sklearn\new\numpy-1.13.1+mkl-cp27-cp27m-win32.whl 3、安装matplotlib-1.5.3-cp27-cp27m-win32.whl ===D:\软件\python\setup\Scripts>>pip install D:\软件\Sklearn\new\matplotlib-1.5.3-cp27-cp27m-win32.whl 4、安装scipy-0.19.1-cp27-cp27m-win32.whl ===D:\软件\python\setup\Scripts>>pip install D:\软件\Sklearn\new\scipy-0.19.1-cp27-cp27m-win32.whl 5、安装scikit_learn-0.19.0-cp27-cp27m-win32.whl ===D:\软件\python\setup\Scripts>>pip install scikit_learn-0.19.0-cp27-cp27m-win32.whl 出现问题：raise ReadTimeoutError(self._pool, None, 'Read timed out.') ReadTimeoutError: HTTPSConnectionPool 解决方法:设置超时时间 ===D:\软件\python\setup\Scripts>>pip --default-timeout=100 install -U sklearn 二、安装过程遇到的一些问题： 1、File "C:\Python27\lib\ntpath.py", line 85, in join result_path = result_path + p_path UnicodeDecodeError: 'ascii' codec can't decode byte 0xc0 in position 0: ordinal not in range(128) 解决办法：D:\软件\python\setup\Lib\ntpath.py 85行改为： sysencoding = sys.getfilesystemencoding() try: result_path = result_path + p_path except UnicodeDecodeError : result_path = result_path.decode(sysencoding).encode(sysencoding)+p_path.decode(sysencoding).encode(sysencoding) 2、File "d:\软件\python\setup\lib\site-packages\pip-9.0.1-py2.7.egg\pip\wheel.py" ，line 184, in fix_script exename = sys.executable.encode(sys.getfilesystemencoding())UnicodeDecodeError: 'utf8' codec can't decode byte 0xc8 in position 3: invalid continuation byte
解决办法： try: exename = sys.executable.encode(sys.getfilesystemencoding()) except UnicodeDecodeError : exename = sys.executable.decode(sys.getfilesystemencoding()).encode(sys.getfilesystemencoding())
