无法在 python 中导入 tensorflow，windows 10 64 位

Question

我正在尝试使用 python 制作一个 AI 聊天机器人。 这需要张量流。 我使用 pip 安装它，当我尝试导入它时，它不起作用。 我得到了这个回溯：

Answer 1

请按照TensorFlow 网站的说明进行操作。 如果您使用较低版本，我建议安装 Tensorflow 2 。

您需要从此处下载并安装/更新 Microsoft Visual C++ 2015-2019 Redistributable (x64)。

如果您面临任何其他问题，可能的原因是

• 您的 CPU 不支持 AVX2 指令
• 你的 CPU/Python 是 32 位的
• 有一个库位于不同的位置/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。
