Error only while using the debugger in VSCode

[sophia-wright-blue]

hello - I'm able to run a script in VSCode, but get an error only while using the VSCode debugger - I have shared the details along with a reproducer on the Julia VSCode extension repo here:

julia-vscode/julia-vscode#3349

and one of the contributors was kind enough to look into the error and has ID'ed the root cause as an issue with JuliaInterpreter - the stack trace of the error are in the comment here:

julia-vscode/julia-vscode#3349 (comment)

it'd help us out greatly if we could get some feedback on resolving the issue - thank you so much!

Sorry this took so long to fix. New version coming: JuliaRegistries/General#89435

[sophia-wright-blue]

thank you so much - I'll test this right away

You may want to use A of smaller size (e.g., 128x128), the interpreter is slow.

hello @timholy - quick update on this - the julia-vscode extension has been updaed to use a recent version the Interpreter and the issue has been resolved - thank you so much for your help!

[timholy]

Thanks for the feedback, that means a lot!

[sophia-wright-blue]

absolutely - one final question for you - you mentioned that the interpreter is slow - I'm finding the difference to be many orders of magnitude: 10 min while debugging vs 30 seconds to run the same script normally - is there any way to improve on that time?

[timholy]

Someday, yes, but a game-changing improvement in performance can't happen until a ton of engineering work gets done first. Julia is a difficult language to interpret efficiently, in part because so much of Julia is written in Julia. (It's pretty easy to interpret call_C_because_I_cant_do_anything_fast(args...) 😉.)

One trick, though, is that any slow operations that you don't need to step into could be run in "compiled" mode. There are some threads on discourse about this.

[sophia-wright-blue]

perfect - I'll go throught the threads on Discourse - thank you so much again!

There's also a bit of documentation here.
