【问题描述】：

昨天我安装了一个 tensorflow 版本。它安装完美，没有任何错误。我的笔记本电脑上还安装了 NVIDIA geforcr 1050 ti 显卡。

import tensorflow as tf

而且我遇到了错误。请有人帮忙。我已经通过命令pip install tensorflow-gpu 通过anaconda 提示安装了它。

Failed to load the native TensorFlow runtime.

我基本上得到如下导入错误：ImportError: DLL load failed: The specified module could not be found.

【解决方案1】：

由于您在 anconda 构建中工作，您应该使用 conda 来安装包，而不是 pip。

因此，您应该使用conda install tensorflow 而不是pip3 install tensorflow。这应该可以正确安装 tensorflow。

如果您仍然遇到问题，可能与您的 CUDA 版本有关。据我了解，tf 目前支持 CUDA 9 和 CUDA 10，但要使用 CUDA 10，您需要从源代码构建 tf。所以你可以降级到 CUDA 9，或者从源代码编译。从源代码编译的说明太复杂了，无法进入 SO，但其他人已经写过它elsewhere
