使用 anaconda 和 VS Code 运行 numpy

Question

我正在尝试让 VScode 与 anaconda 一起使用，但在使用 numpy 时遇到问题。我已经设法让 VScode 使用正确的 python 环境 从 VScode （ctrl+shift+P，输入 Python:Select Interpreter 并选择适当的选项）。

但是，当我在脚本中输入“import numpy”时，我收到以下错误消息：

C:\ProgramData\Anaconda3\envs\sandpit\lib\site-packages\numpy\__init__.py:140: UserWarning: mkl-service package failed to import, therefore Intel(R) MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured. Please install mkl-service package, see http://github.com/IntelPython/mkl-service

    from numpy.core._multiarray_umath import (
ImportError: DLL load failed while importing _multiarray_umath: The specified module could not be found.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "c:\Users\[NAME]\Documents\python\sandpit\hello.py", line 2, in <module>
    import numpy
  File "C:\ProgramData\Anaconda3\envs\sandpit\lib\site-packages\numpy\__init__.py", line 142, in <module>

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

Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
  1. Check that you expected to use Python3.8 from "C:\ProgramData\Anaconda3\envs\sandpit\python.exe",
     and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy version "1.18.1" you're trying to use.
  2. If (1) looks fine, you can open a new issue at
     https://github.com/numpy/numpy/issues.  Please include details on:
     - how you installed Python
     - how you installed numpy
     - your operating system
     - whether or not you have multiple versions of Python installed
     - if you built from source, your compiler versions and ideally a build log

- If you're working with a numpy git repository, try `git clean -xdf`
  (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.

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

我已经从 anaconda 命令提示符成功调用了“import numpy”命令，所以看来问题只是与 VS-Code 有关？

我还尝试使用以下命令从环境中重新安装 numpyconda install numpy --force-reinstall但这没有效果？

尝试从激活的 conda 环境启动 VS Code。如果您在 shell 有机会激活 conda 环境之前设法运行代码，通常会出现此类错误。
