在安装tensorflow完成后，import tensorflow as tf出现问题，问题如下：

>>> import tensorflow as tf
Traceback (most recent call last):
  File "I:\Anaconda3\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *
  File "I:\Anaconda3\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 28, in <module>
    _pywrap_tensorflow_internal = swig_import_helper()
  File "I:\Anaconda3\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
  File "I:\Anaconda3\lib\imp.py", line 242, in load_module
    return load_dynamic(name, filename, file)
  File "I:\Anaconda3\lib\imp.py", line 342, in load_dynamic
    return _load(spec)
ImportError: DLL load failed: 动态链接库(DLL)初始化例程失败。

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/errors

for some common reasons and solutions.  Include the entire stack trace
above this error message when asking for help.

问题原因：

tensorflow的新版本不支持比较老的cpu（我这个老机器表示很桑心）

解决办法：

卸载现有的tensorflow，安装tensorflow1.5版本

依次执行：

pip uninstall tensorflow

pip install tensorflow==1.5 -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com

成功
