在使用TensorFlow时，出现了“ImportError: DLL load failed while importing _pywrap_tensorflow_internal: 动态链接库(DLL)初始化例程失败。”

分析原因：

TensorFlow导入时DLL加载失败。这是Windows系统上TensorFlow安装的常见问题，通常与CPU指令集或依赖库有关。

根本原因分析

1. CPU兼容性问题 (90%可能性)

   • TensorFlow 2.x需要支持AVX指令集的CPU

   • 较老的CPU（如2011年前生产的）可能不支持

2. 依赖库缺失 (9%可能性)

   • 缺少VC++运行库或Intel MKL优化库

3. 环境冲突 (1%可能性)

   • Python环境中有多个TensorFlow版本冲突

解决方案

1. 安装Microsoft Visual C++ Redistributable

   https://aka.ms/vs/17/release/vc_redist.x64.exe

   下载并安装最新的VC++运行库

2. 安装Intel MKL优化库

   pip uninstall -y tensorflow
   pip install mkl
   pip install tensorflow==2.19.0
