Tensorflow 2 适用于 Jupyter Notebook 但不适用于 VsCode

Question

这个带有 tensorflow 2.2.0 的代码可以在 Jupyter Notebook 上运行，但在 VsCode 上会出错。
我怀疑在 VsCode 中自动生成的 settings.json 中的“python.pythonPath”。
不知道如何配置 VsCode。

import tensorflow as tf
print(tf.__version__)

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.8 from "C:\Users\<User>\Anaconda3\envs\tf2\python.exe"
  * The NumPy version is: "1.18.5"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.

尝试从您激活的 conda 环境中启动 VS Code，然后确保它被 Python 扩展选中（查看状态栏）。这应该可以解决 sys.path 中的差异。
