@viewstar000 Please could you try uninstalling and re-installing the extension.

[toplinuxsir]

I have experienced the same problem and ,
re-installing the extension doese not work !
vscode version: 1.9.0
ms python extension: 0.9

@toplinuxsir
Thats odd, in issue #427 you claim to have version 0.9 installed and don't have this issue?
Please could you update the issue (#427) with the errors logged in your console window.

I'd like to know whether you're experiencing the same issue or not, right now I'm confused with the information you have provided.

Does this provide something? startup is set to false.

{
	"activationTimes": {
		"startup": false,
		"codeLoadingTime": 1,
		"activateCallTime": 0,
		"activateResolvedTime": 0,
		"activationEvent": "onLanguage:python"
	}
}

@DonJayamanne
Yesterday at company, different computer, Today is Saturday ,At home ,
My home computer has just experienced the problem , But when I re-installing the vscode and python extension, It works

@SShehriyar
Are you also experiencing this same issue.

• Please confirm you have updated both VS Code and the extension to the latest version.
• Have you tried reinstalling the extension.

@DonJayamanne Yes, I ran into this yesterday after updating VS Code to 1.19. I can confirm that I'm running the latest versions of both of them (1.19.0, 0.9.0). I have tried reinstalling the extension but the error persists. Running any command of the extension just gives an Error saying command 'python.command' not found and @viewstar000 has already provided the logs.

@DonJayamanne I had Visual Studio Code Tools for AI extension installed. It also had some error messages in the developer tools console log. I uninstalled it and the python extension is now working.

EDIT: Can confirm Visual Studio Code Tools for AI extension is causing the python extension to not work (for me) as i uninstalled it and the python extension worked and when i reinstalled it the python extension does not work. Might have something to do with the fact that the AI tools extension isn't supported on linux I believe.

@SShehriyar thanks for that information, will look into this. Thanks
