Looks like this may be happening because you are using an older version of the AutoML package against latest version of polyglot notebooks extension.

Could you try updating to the latest version from nuget.org? This version which was released last week may fix the error https://www.nuget.org/packages/Microsoft.ML.AutoML/0.21.0-preview.23511.1https://www.nuget.org/packages/Microsoft.ML.AutoML/0.21.0-preview.23511.1.

This is the same issue as #3244 and #2366. We are currently investigating a fix for this.

[cartercanedy]

@shyamnamboodiripad is there already a branch created for this fix in another fork?

Just saw this, nevermind

[cartercanedy]

I have noticed that the hanging is still persistent, though

[shyamnamboodiripad]

Could you please clarify the exact repro steps for the hang? Am I correct in assuming that the hang only happens when the AutoML extension is in play? Is there a particular notebook that you are able to repro the hang with?

[cartercanedy]

That code submission should've only taken 10 secs (per awaiting that sleeping promise), but it only completes on the first submission, any subsequent submissions of the unaltered code hang.

[shyamnamboodiripad]

Thanks for sharing the repro @cartercanedy. I am also able to repro this with the code you shared below. Sometimes I am able to cancel execution, other times it hangs and yet other times, the cell completes.

sleep = (ms) => new Promise((resolve) => setTimeout(resolve, ms));
await sleep(10000);
const someVar = "Hello, world";

We will take a look - more than half of our team is away this week so it may be next week before we can get to this.

(cc @colombod FYI looks like there are some more problems beyond what we fixed in #3268)

[shyamnamboodiripad]

@superichmann Is the hang you were running into above similar to the one @cartercanedy reported above? Are you also running into the hang in JavaScript? Please share a repro if you think it is different.

[superichmann]

TLDR: FIXED, changed Microsoft Data analysis with version 0.21.0-preview.23511.1

I am keeping this open in case you want to change the infinite run behavior and if you would want to reproduce. feel free to close.

This is exactly what is happening on my side:

1. I am creating new notebook
2. I save the notebook as a file (ipynb)
3. I add this to the first cell:

Console.WriteLine("Initializing...");
#r "nuget: Microsoft.ML,3.0.0-preview.23511.1"
#r "nuget: Microsoft.ML.TimeSeries,3.0.0-preview.23511.1"
#r "nuget: Microsoft.Data.Analysis"
#r "nuget: Microsoft.ML.AutoML,0.21.0-preview.23511.1"
#r "nuget: Microsoft.ML.OneDal,0.21.0-preview.23511.1"
#r "nuget: npgsql"
#r "nuget: Telegram.Bot"
#r "nuget: MathNet.Numerics"

5. I run the first cell, get this output after 4 seconds:

6. I run the cell again, it never ends running - continuous infinitely

I have tried restarting vs code and it didn't help

if further information is needed from my side please tell me how to obtain it and I will add it here

[princeanire]

Hi, I encountered this also, when i tried running the following code
while (true)
Console.WriteLine("Please stop!");

clicking the Stop execution button doesn't stop the execution and I have to restart the .NET interactive kernel for it to stop

[jonsequitur]

@princeanire, this is unrelated. The cancel button will not cancel infinite loops, since .NET Core / .NET 5 / .NET 6 did not support an equivalent of .NET Framework's Thread.Abort. We are working on a potential fix using the ControlledExecution API introduced in .NET 7.
