在安装正确的CUDA Reference 1，Reference 2

后尝试访问

Answer 2

我在Windows 7上没有CUDA的conda环境中安装Tensorflow 2.x时遇到此错误。

最终，作为设置新的conda环境的一部分，我设法安装了Tensorflow。这是管理安装的我的环境文件：

# This file defines a conda environment.
# Run as: conda env create -f dev_environment.yml
# Remove old environment using: conda env remove --name dev
name: dev
channels:
  - conda-forge
dependencies:
  - python=3.7
  - notebook
  - numpy
  - pandas
  - tensorflow-mkl=2.1  # <-
  - tensorflow-estimator==2.1  # <- (Needed to avoid AttributeError)

我还安装了installation docs中提到的Microsoft Visual C ++ Redistributable，作为我搜索工作的一部分，但我不确定这是否至关重要。

更多说明：

在撰写本文时，conda上已经可以使用tensorflow 2.2，但是给出了AttributeError when importing
使用pip总是会出现OP（pip install tensorflow或pip install tensorflow-cpu）描述的错误。我不确定pip和conda版本之间有什么区别。
Tensorflow hardware requirements提到TF从版本1.6开始使用AVX cpu指令。但是，我能够使用具有Intel i9 cpu的机器在不支持AVX指令的计算机上使用上述方法安装TF。

ImportError：DLL加载失败，错误代码为3221225501 Tensorflow
