import numpy could not be resolved message error; ipynb in vscode

I opened two ipynb files in vscode, and one is showing error messages.

this is first file and

this is second file.

i can run both files without any problems. But those error alrams are really annoying. How can i get rid of it? those messages are from extension named error lens. Is there any problem with it?

Try the next three methods

• Ctrl+K+T switch theme

• Add the following settings

      "editor.semanticHighlighting.enabled": true,
      "python.languageServer": "Pylance",
  

• Add the package path with the following settings

      "python.analysis.extraPaths": [
          "input/lib/path/here"
      ],
      "python.autoComplete.extraPaths": [
          "input/lib/path/here"
      ],
