TensorFlow DLL 加载失败：动态链接库 (DLL) 初始化例程失败

Question

我在我的 PC 上安装并运行了 TensorFlow。当我运行它时，这个错误出现在 jupyter notebook 中。我多次尝试使用 Python 3.6 重新安装 Anaconda，但总是遇到同样的错误。我试图安装一个新的操作系统 并为 Visual Studio 2015 安装 Visual C++ Redistributable，但没有任何改进。 我也看到了this url，但它告诉我安装具有某些功能的 Visual Studio 2015。我安装了 Visual Studio 2015，但没有帮助。

提前致谢

Answer 1

这些可能是可能的情况：

1.You need to install the MSVC 2019 redistributable
2.Your CPU does not support AVX2 instructions
3.Your CPU/Python is on 32 bits
4.There is a library that is in a different location/not installed on your system that cannot be loaded.
