Tensorflow 2.1.0 - DLL 加载失败 - windows cpu

Posted 2023-02-18

【中文标题】Tensorflow 2.1.0 - DLL 加载失败 - windows cpu

【英文标题】：Tensorflow 2.1.0 - DLL load failed - windows cpu

【发布时间】：2020-06-02 07:12:07

【问题描述】：

TensorFlow 2.1.0 安装成功，但 TensorFlow 导入失败。

开放式问题：

是否存在无法加载的位于不同位置/未安装在系统上的库？

复制程序：

1) 创造环境

conda create --name tensorflow21_env

2) 激活环境

conda activate tensorflow21_env

3) 安装

conda install python=3.7 pip install tensorflow-cpu #install tensorflow=2.1.0;

4) 测试

python -c "import tensorflow as tf"

更新：

我的处理器既不支持 AVX 也不支持 AVX2，因此无法安装 tensorflow pip 包，或者更准确地说，无法导入 tensorflow 包。

临时解决方案：

不支持 AVX 的旧版和低端 CPU 的临时解决方案是为 tensorflow 安装 SSE-prebuild-binaries。 转到 tensorflow-windows-wheel 并按照说明安装 tensorflow 2.0.0 或 2.1.0。

【参考方案1】：

试试这个方法： 卸载您使用 pip 安装的 TensorFlow 包，然后使用 conda install tensorflow 重新安装，这可能有效！现在您可以毫无问题地导入 TensorFlow。我希望这可以帮助你。

如果您需要更详细的步骤。在这里，您可以执行以下操作。

以管理员身份运行 anaconda 提示符。 （右键->以管理员身份运行）。

pip uninstall tensorflow

关闭 anaconda 提示符。

再次以管理员身份运行 anaconda 提示符。

类型： conda install tensorflow 它会要求一些y / n 输入y。

现在完成后，将 python 解释器的环境更改为安装 tensorflow 的 anaconda 环境。

现在尝试导入 tensorflow。

我希望这会有所帮助。

【讨论】：

有人试过这个答案吗？我不想卸载 tensorflow 2.0，因为我很难安装它？

我试过 conda install tensorflow 作为卸载它。 (1) 我没有收到 TF 安装成功的消息 (2) 当我导入 tensorflow 时出现错误 ImportError: DLL load failed: The specified module could not be found.我真的很挣扎，因为我认为这里的说明会帮助我medium.com/analytics-vidhya/…
