安装tensorflow以及python过程中的一系列问题

1.错误pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

解决方法：

重新编译python：

./configure --with-ssl

make

make install

参考：https://www.aliyun.com/jiaocheng/517957.html

2.错误ImportError: /usr/local/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so: undefined symbol: PyUnicodeUCS4_FromStringAndSize

解决方法：

重新编译python：

./configure --prefix=/usr/local/python27 --enable-unicode=ucs4

然而不幸的是，虽然解决了这个问题，又有下一个问题：

    Original error was: /usr/local/lib/python2.7/site-packages/numpy/core/multiarray.so: undefined symbol: PyUnicodeUCS2_FromObject

吐血，没能解决

3.import numpy 报错

试了各种办法，最后还是不成功，放弃了......

tensorflow从安装到放弃...

续：

——import numpy 报错：

ImportError:
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

Original error was: /usr/local/lib/python2.7/site-packages/numpy/core/multiarray.so: undefined symbol: PyUnicodeUCS2_FromObject

百度了很久，尝试重新安装numpy，用apt-get 和pip均不成功。但用pip安装时有提示说Requirement already satisfied*****。进入python的目录，/usr/local/lib/python2.7/site-packages 里面有文件夹numpy和numpy-1.14.5.dist-info。推测是由于它们存在所以不能重新安装，删掉这两个文件夹，再用pip安装，再import就成功了。

 

注：为了同时解决错误1和错误2，再configure的时候我用的命令是

./configure --enable-unicode=ucs4 --with-ssl

然后再make -> make install
