我在尝试运行 TensorFlow 程序时遇到以下错误：

$ python3 
Python 3.5.2 (default, Nov 17 2016, 17:05:23) 
[GCC 5.4.0 20160609] on linux

>>> import tensorflow as tf
Traceback (most recent call last):

    _pywrap_tensorflow_internal = swig_import_helper()

    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)

    return load_dynamic(name, filename, file)

    return _load(spec)
ImportError: /usr/local/lib/python3.5/dist-packages/tensorflow/python/_pywrap_tensorflow_internal.so: undefined symbol: cudnnConvolutionBiasActivationForward

During handling of the above exception, another exception occurred:

无法加载原生 TensorFlow 运行时。

见https://www.tensorflow.org/install/install_sources#common_installation_problems

出于一些常见原因和解决方案。包括整个堆栈跟踪寻求帮助时出现此错误消息。

系统信息： Ubuntu 16.04 库达 8.0 库顿 5.1 tensorflow-gpu 版本

【问题讨论】：

这不是一个很好的答案，但看起来这个问题已经通过重新安装或强制安装得到解决：github.com/tensorflow/tensorflow/issues/12326

标签： tensorflow python-3.5

【解决方案1】：

As mentioned here，强制重新安装应该可以解决问题，或者降级到较低的 tensorflow 版本也可以：

pip3 install tensorflow-gpu --upgrade --force-reinstall

此问题的一个可能原因是您同时安装了 tensorflow-cpu 和 tensorflow-gpu。
