python3 重新编译

      今天运行一个python3写的深度学习的程序。遇到了如下的问题

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/theano/gof/lazylinker_c.py", line 92, in
    raise ImportError()
ImportError


During handling of the above exception, another exception occurred:

解决方案：
1）官网下载Python3的代码
2）使用如下命令来生成Makefile
./configure --enable-shared CFLAGS=-fPIC --enable-optimizations
3）重新编译、安装
   make install
