So looks like I should start with the fact there is no settings.json file in .vscode?

I also don't have "conda" on the path, though I do have the conda environments on the path.

OK, so I added settings.json in .vscode
my python.pythonPath in settings.json in .vscode looks like this:
"python.pythonPath": "C:\PyAna2\envs\pandas36\python.exe",

No change in the timeout behavior - still does not connect and times out

Also, this is Windows 10 professional release 10.0.17134

Dug into conda location.
I have conda.bat located in C:\PyAna2\Library\bin
I also have C:\PyAna2\Library\bin on my path

Please could you confirm the following file exists:
C:\PyAna2\envs\pandas36\python.exe
Please modify settings.json to add the file path as follows:
"python.pythonPath": "C:\\PyAna2\\envs\\pandas36\\python.exe",

Note, this is a JSON file hence back slashes need to be encoded.

Instead of manually editing the settings.json, please could you select a python interpreter from the UI.
Either use the command Python: Select Interpreter or use click on the status bar item (either Please Select Interpreter or <Some Python Interpreter Information>
Finally, please try install the latest development version of the extension from here and give it a go. https://github.com/Microsoft/vscode-python/blob/master/CONTRIBUTING.md#development-build

Hi Don, thanks for getting back to me with these suggestions.

Confirmed C:\PyAna2\envs\pandas36\python.exe exists both by file manager and activating the pandas36 environment in conda and running a notebook from that activated environment.

When I loaded settings.json, the double backslashes had already been changed / fixed.

"python.pythonPath": "C:\PyAna2\envs\pandas36\python.exe",

Tried debugger connection - still a timeout and no connection

Finally, I tried the insiders VSIX file, it did not load.

Got this error message:

/C:/Program Files/Microsoft VS Code/resources/app/out/vs/workbench/workbench.main.js:2407 Sorry, something went wrong activating IntelliCode support for Python. Please check the "VS IntelliCode" output window for details.

I used View:Toggle Output a couple of times but am not seeing anything in the output window that is helpful. I'm cycling through Problems / Output / Debug Console / Terminal "tabs" and also all combinations of the pulldown on the right.

Tried to connect debugger again, no connection.

How would I uninstall the VSIX file?

Please send a screen shot of the contents in settings.json
To install the vsix, just uninstall the python extension and quit vscode.

I was testing for issue #2698 and faced similar issue with in-development build vsix. F5 started the debugger for Python-Flask debug config, it gets hung. Similarly with Python-Current File debug config, if any of the module imports fails, exception is not shown on the terminal, but the debugger get hung.

I pressed Ctrl+C to break, and got the below stack

Brett Two machines – both showing identical response – both running a long script that I don’t want to kill at the present. Both have been running VS pretty continuously for the last couple weeks. #1 – had the issue with this one first. It was standard Win 1803 when it occurred – submitted a issue a couple of days ago that was closed too quickly in my view – I have since done a full clean install completed last night including a full fresh conda and python install. Not sure what level of VS or extension I was at when it first went bad. I made a big mess of it trying to fix which lead to the decision to fresh install. Simple refresh did not work as all the Anaconda stuff part of my user files, which were retained in a refresh. Full clean install taken to wipe all of that out. I did nothing on either machine with regards to the terminal type – always been default powershell. 1.28.1 2018.9.0 Windows 10 1803 Python 3.7.0 conda 4.5.11 ‘false’ - works like a charm. - default No entry following clean install it did not work. - removed the false line – no longer works after a reload of VS – until than its OK - add false back in – works fine again without the need to reload VS #2 – issue just arose yesterday after I did a reboot. Can’t recall the last previous reboot. This machine on Win 10 fast track and has had 1809 since 9/15/2018 OS build 17758.1 So for my machines the issue has nothing to do with the October release of Win 10 and everything to do with the VS and extension updates. 1.28.0 2018.9.0 Win 10 1809 Python 3.6.5 conda 4.5.11 ‘false’ – works like a charm. Sent from Mail for Windows 10 From: Brett Cannon Sent: Friday, October 12, 2018 12:26 PM To: Microsoft/vscode-python Cc: PCJimmmy; Mention Subject: Re: [Microsoft/vscode-python] Timeout waiting for debugger connectionwhen using Windows PowerShell (#2732) We believe there are two issues going on (PowerShell not activating fast enough under conda to get the debug command, and a potential issue related to the Windows 10 October 2018 release regardless of environment activation), and due to the amount of comments here it has become hard for us to tell what configurations are leading to failures. If people can provide the following it would be really helpful: 1. The information listed in the table below (I will update it as people's responses come in) 2.

Two machines – both showing identical response – both running a long script that I don’t want to kill at the present.

Please could you try running a new simple script such as print("Hello")

Same issues repeated on 3 different PC.

All the configuration are all the same as below:

VS Code version	Python extension version	Windows 10 version ("About your PC")	PowerShell version (`$PSVersionTable.PSVersion`)	Python version	Python environment	Environment activation (`"python.terminal.activateEnvironment"`)	Debugging works
1.28.1	2018.9.0	Windows 10 1709	PS 5.1 16299	Python 3.7.0	conda 5.3	`true`	N

Thanks to everyone for the help! We're fairly certain we have eliminated the Windows 10 October 2018 worry and corroborated that this is all because our hack around conda's lack of PowerShell support just isn't robust enough based on the APIs that VS Code provides us. We are going to get a fix out that will let you know that conda + PowerShell are not a good combination for debugging (conda should have the support necessary in conda 4.6). We will also make it easy to switch your terminal over to command prompt so that you can still debug with an activated conda environment. Otherwise you can disable environment activation and stick with PowerShell if you prefer while still being able to debug.

just open the lauch.json file and add the following configuration:

{
     "name": "Python: Debug Console",
     "type": "python",
     "request": "launch",
     "program": "${file}",
     "console": "none"
}

When you specify "none" for the console, it will run the debugger in the debugger console instead of running in the internal or external terminal.
And it will work

@Beta3-Data yes, but it won't activate your conda environment either which many people want/expect.

just open the lauch.json file and add the following configuration:
{
     "name": "Python: Debug Console",
     "type": "python",
     "request": "launch",
     "program": "${file}",
     "console": "none"
}

just did this and issue continues, I have set two things
activate environment to false
added the above into launch.json

am I the only one with the issue, please I see others have closed it.
I am trying to use python for testing azure functions other than using C#.
and thought vs code with its deep integration will be useful.

Sriram Muthukrishnan (@srirambm)

Sriram Muthukrishnan (@srirambm) if you are using conda w/ PowerShell then either don't use conda or switch to Command Prompt. If you're not using conda w/ PowerShel then you have a different issue.
