Also want to note that this doesn't happen in Python 3.7.3. Looks like an issue specific to Python 3.8.0.

[IanMatthewHuff]

@fafaci. Thanks for the report on this. I'll grab 3.8 and check if I can repro this quick.

[IanMatthewHuff]

@fafaci. How did you set up your 3.8 environment? I'm not seeing some of the jupyter stuff that we would need for running the interactive window ready for 3.8 yet.

[rafaci]

@IanMatthewHuff, thanks for the follow up. I didn't really do anything special. Here's how I setup my environment:

1. Downloaded Python 3.8.0b4 from https://www.python.org/downloads/release/python-380b4/
2. Opened VS Code in an empty folder
3. Created a virtual environment using py -m venv venv
4. Selected the interpreter in my venv.
5. Opened the command palette and ran the Python: Show Python Interactive window command.

[IanMatthewHuff]

@rafaci. Hmm, that's interesting. As of now (at least on Windows when I just checked) with just the basic Python 3.8.0b4 install there are not yet many packages like jupyter and numpy that we require to run our interactive window. Could you do something like a pip list to show what you have installed in that venv? I'm interesting in seeing what version of jupyter you have.

[rafaci]

@IanMatthewHuff Ah I think I get what you're saying now. I forgot to install jupyter in this new venv and after trying to install jupyter in my environment I notice that the installation raises an exception. I get a stack trace with the following final message:
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

I guess we'll have to wait until numpy, jupyter, etc. are fully support 3.8, correct?

[IanMatthewHuff]

@rafaci. Yeah that is the error that you'll see when a package is not currently available in pip or conda for that version of python. I believe there is a way to use conda-forge to configure pre-3.8 packages so I'm looking into that now. While the root cause here is the lack of jupyter in that environment I'm keeping this issue open as we didn't surface a reasonable warning here for you. Which I'd like to fix. If our code doesn't find Jupyter in the currently selected environment it looks for other environments on disk to use instead, I believe that this probably started up the server from an old environment, and then failed trying to create a 3.8 kernel in it.

[greazer]

Test to see how things are working. If changes are needed, enter a new issue.

[Zireael]

Possibly due to asyncio changes
tornadoweb/tornado#2608

[rafaci]

I'm still having issues. I'm suspecting the issue is related to the change Zireael pointed out. As requested, I created a new issue: #2837.

[IanMatthewHuff]

Hey @rafaci and others. Just to check here, in the 3.8 environment that you have selected in VSCode are you able to, from a command prompt from that same environment, run jupyter server to start up a jupyter server instance and connect a notebook to it? Some of the issues mentioned above sound like they might be general 3.8 configuration issues, like the tornado issue. VSCode uses the jupyter notebook command to start up our backing server, so if you don't have the correct configuration in that 3.8 environment to run from the command line then VSCode is also not going to work.

[rafaci]

Sorry for getting back so late. So it looks like this is a bug with jupyter and tornado. I searched online and found that jupyter should work if I add the following to the asyncio.py file:

if sys.platform == 'win32':
    asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

After doing that, I was able to successfully run py -m jupyter in the Python terminal and connect to it via my browser; however, it still fails in vscode. It looks like it fails to import a DLL?
