Visual Studio：未解决的导入“numpy”

我正在尝试运行下面需要numpy的代码。我通过pip install numpy. 但是，numpy 会在编辑器中突出显示，并带有注释unresolved import 'numpy'。当我尝试运行它时，我收到错误No module named 'numpy'。第一次出现错误后，我卸载了 numpy 并重新安装了它，但问题仍然存在。

我正在使用 Python 3.7.8 和 NumPy 1.20.2。

我试图运行的代码：

Super Mario Bros level extractor
This script requires py65emu, numpy, and PIL to run.  Run with no arguments to see usage.
See http://matthewearl.github.io/2018/06/28/smb-level-extractor/ for a description of how this was written.
To run you'll need to compile https://gist.github.com/1wErt3r/4048722 with x816 to obtain the PRG-ROM and symbol files.
The CHR-ROM should be extracted from a Super Mario Bros ROM, or can be read from an INES ROM file.  See
https://wiki.nesdev.com/w/index.php/INES for information on the INES format.  In addition you'll need a NES palette
saved in "data/ntscpalette.pal", generated using the tool here: https://bisqwit.iki.fi/utils/nespalette.php
