无法导入tensorflow无法加载本机tensorflow运行时

Question

我已经通过Python使用tensorflow有一段时间了。今天，我的电脑死机了，我不得不重新安装Anaconda，今天安装tensorflow后，每次我尝试导入它时，我都会出现以下错误-

(base) C:\Users\Pragyaditya Das>python

    return _load(spec)

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.

当我执行pip freeze | findstr tensorflow时，我会得到以下详细信息-tensorflow==2.1.0 tensorflow-estimator==2.1.0

我在这里和tensorflow的github repo中浏览了各种答案，但都是徒劳的

任何形式的帮助都将提前得到感谢

Answer 1

当我在等待答复时，我能够自己解决错误。 分步指南如下：

1. 安装VS 2017，tensorflow不使用它，但它有助于顺利安装CUDA工具包
2. 从windows设备管理器更新NVDIA驱动程序
3. 下载并安装CUDA工具包（10.1版）
4. 下载并解压缩CUDnn 7.6.5。将提取的文件复制到C驱动器中的文件夹中
5. 将~\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin、~\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin和cudnn-10.1-windows10-x64-v7.6.4.38\cuda\bin添加到路径

在上述步骤之后执行import tensorflow as tf可以解决问题
