Tensorflow 没有在 miniconda 和 jupyter notebook 上运行

Question

我已经使用 pip install 安装了 tensorflow，但它没有运行。

尝试运行它时，我收到以下错误消息：

无法加载原生 TensorFlow 运行时。

请帮我运行 tensorflow。

Answer 1

卸载 tensorflow，然后使用 conda 重新安装。 Conda 将安装 tensorflow 2.1.0、cuda 工具包 10.1.243 和 cudnn 7.6.5。 Pip 不会安装工具包或 cudnn，您必须下载它们并更改环境路径变量以指向存储它们的目录。如果要安装 tensorflow 2.2，首先使用 conda 安装 tensorflow 2.1.0，然后使用 pip 安装 tensorflow 2.2，使用 pip install tensorflow ==2.2.0。 TensorFlow 2.2 兼容 2.1 安装的 toolkit 和 cudnn 版本。

Answer 2

尝试使用pip install tensorflow 代替 conda。 Tensorflow 对我来说很好用。但是我还没有尝试使用 conda 来安装 tensorflow。
