Stack trace:

What you expected to happen:

@george-zubrienko are you able to test the connection from non-arm environments?

[george-zubrienko]

@ion-elgreco yes if I change machine type to amd64 it works fine. Fun part, people on Mac M2's do not have this issue

I'm building a new image rn with 0.17.3, fyi this was the wheel used by ARM64 build: deltalake-0.17.2-cp38-abi3-manylinux_2_17_aarch64.manylinux2014_aarch64.whl

Same result with 0.17.3. I assume the error is coming from Rust code, not python as it is reported as OSError

Could you do a bisect, to see which release this problem started occurring for you?

We just upgraded from 0.8.1 to 0.17.* and I got the error. I can try to narrow it down a little. In case this adds anything, we are loading data like this: https://github.com/SneaksAndData/adapta/blob/main/adapta/storage/delta_lake/_functions.py#L39-L90

[george-zubrienko]

@ion-elgreco it works up to 0.16.1, 0.16.2 breaks it

[ion-elgreco]

@george-zubrienko hmm strange, nothing implies there is a change that could have caused this in that release.

Maybe its the rust version which it gets compiled with, are you able to compile with some older version and check that

Arent 0.16.2 and 0.16.1 compiled with the same version? I can try to force this package to compile from source rather than use the wheel

[george-zubrienko]

@ion-elgreco

So, using this compiler version:

# rustc --version
rustc 1.78.0 (9b00956e5 2024-04-29)

Running this:

# pip install --upgrade deltalake==0.17.2 --no-binary :all:

Everything works. So it is a problem with the wheel?

@george-zubrienko ok that's helpful!

I think it's because of the rust compiler.

• V0.16.1 was compiled with rust 1.76.0
• v0.16.2 until v0.17.3 is compiled with 1.77.x

You seem to get it working when it's compiled with 1.78.0

[george-zubrienko]

That is the case! Any chance we can get compiler bumped for 0.17.4? 🙏

[ion-elgreco]

Probably next release. Rust 1.78 got released today and our release just missed that version

[gaurav7261]

I'm also facing same issue with aws sts, using latest deltalake version

[gaurav7261]

@ion-elgreco tag me here once you release the latest version, right now we are reverting back to amd

[rtyler]

I would be surprised if this was the compiler. It is more likely that a dependency for which we have a loose version range specifier. Either way, I figure the next release should take care of this for ya :smile:

[gaurav7261]

@rtyler we are also facing same with aws as well

[ion-elgreco]

@george-zubrienko can you check against v0.18.0 please?

[george-zubrienko]

@george-zubrienko can you check against v0.18.0 please?

Will check on Monday!

[george-zubrienko]

Bit delayed - deploying this as of now, in case I don't get to actually run the validation, will ping tomorrow

[george-zubrienko]

Side note: it seems macOS environments now have issues importing datalake:

This is already reported, see the issues board. Someone also has a workaround to get it still inetalled

[george-zubrienko]

@ion-elgreco I just tried with deltalake 0.18.0 on ARM machine and I'm getting the same error (library installed from wheel, I can try to build from source tomorrow if you want to confirm it still works in that case)

[ion-elgreco]

@george-zubrienko you might give 0.18.1 a shot which includes latest object store version, not sure if it's going to have any impact though

[george-zubrienko]

@george-zubrienko you might give 0.18.1 a shot which includes latest object store version, not sure if it's going to have any impact though

Will try, but... isn't this strange a bit? I've checked the Mac issue as well and I see people also resolve it with no-binary flag to pip. So two issues at this point that are resolved by simply recompiling the rust library - which for me at least tells that this is not related to code. Maybe something changed in your release process?

Yeah the Mac issue got fixed by just bumping the os version of the runners

[george-zubrienko]

@ion-elgreco we just tested with 0.18.1 for both Azure and AWS, the error is gone

[george-zubrienko]

I believe this can be closed as we rolled 0.18.1 on prod with mostly ARM machines and I do not see any failures :) Thanks a lot!

[ion-elgreco]

@george-zubrienko thanks for the update!
