在 windows 上设置 tensorflow 的问题

Question

我安装了最新版本的 tensorflow 2.3，当我尝试导入 tensorflow 时出现以下错误

runfile('C:/Users/Sriram/untitled1.py', wdir='C:/Users/Sriram')

ModuleNotFoundError: No module named 'tensorflow_core'

我下载了一些 msvdp71 zip 文件并将其解压缩并将其复制到我的 sys32 和 syswow 文件夹中，但它对我不起作用。在 colab 中，我训练了一些模型，当我尝试运行它们时，我想在 pc 上运行它们 tf1.6.0 他们给出了与版本相关的错误。所以当我使用 pip 升级它时，我什至无法导入它。

Answer 1

在python中创建一个虚拟环境。创建虚拟环境需要virtualenv库。

pip install virtualenv

安装后创建您的虚拟环境。
命令 - virtualenv "NAME-OF-ENVIRONMENT"

例如

virtualenv myenv

这将创建一个名为 myenv 的目录。要激活您进入 myenv/scripts 文件夹中的虚拟环境，请打开 cmd 提示符并键入 activate。

例如

cd myenv/Scripts
activate

退出脚本文件夹

cd ../..

现在安装 TensorFlow。

pip install tensorflow

Tensorflow 需要各种库才能工作。如您所知，TensorFlow 1.x 和 2.x 不兼容。当您运行升级脚本时，它必须只升级了版本而没有下载依赖项。

注意：在任何项目中工作时始终创建一个虚拟环境，并保持你的 python 包干净。如果它们因任何原因损坏或停止正常工作，您可以删除这些环境，无需担心。
