安装 TensorFlow (2.1.0)[之前我有 2.0.0]

Question

当我尝试在我的 IDLE 中导入 Tensorflow 时遇到错误，我确实再次安装了该软件包，但似乎满足了要求，但导入时出现错误，有人可以帮助我如何安装它没有任何错误。

在 python IDLE 中导入时

Failed to load the native TensorFlow runtime.

Answer 1

ImportError: DLL load failed: 找不到指定的模块。

要修复此错误，您需要从 here 下载并安装/更新 Microsoft Visual C++ 2015-2019 Redistributable (x64)。

如果您遇到任何其他问题，可能的原因是

• 您的 CPU 不支持 AVX2 指令
• 您的 CPU/Python 是 32 位的
• 有一个库位于其他位置/未安装在您的系统上，无法加载。

请参考 Windows CPU 和 GPU 的测试构建配置。

如果您仍有问题，请告诉我，我很乐意为您提供帮助。
