無法導入 tensorflow - 無法加載本機 tensorflow 運行時

Question

我已經通過 Anaconda 使用 tensorflow 有一段時間了。 今天，我的電腦崩潰了，我不得不再次重新安裝 Anaconda，今天安裝 tensorflow 后，每次嘗試導入它時，都會出現以下錯誤 -

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.

當我做pip freeze | findstr tensorflow pip freeze | findstr tensorflow ，我得到以下細節 - tensorflow==2.1.0 tensorflow-estimator==2.1.0

我在這里和 tensorflow 的 github repo 中經歷了各種答案，但徒勞無功。

任何幫助都提前表示贊賞。

Answer 1

在等待回復的過程中，我自己解決了錯誤。 分步指南如下：

1. 安裝VS 2017 ，tensorflow 不使用它，但它有助於 CUDA 工具包的順利安裝。
2. 從 Windows 設備管理器更新NVDIA 驅動程序。
3. 下載並安裝CUDA 工具包（版本 10.1） 。
4. 下載並解壓CUDnn 7.6.5 。 將提取的文件復制到C盤的文件夾中。
5. 添加~\\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到 PATH

在上述步驟解決問題后， import tensorflow as tf 。
