pantab is incompatible with the version of Tableau Hyper API installed on your system

Unsure how to proceed...

Does downgrading to an older version of the hyper api work? The version you have looks to have just been released today with some C-API breaking changes. Will need a PR to support that

@vogelsgesang

[vogelsgesang]

Indeed, the interface of hyper_rowset_chunk_field_values changed with the latest HyperAPI release. Downgrading should fix this, until a solution in pantab is available. Good that we put a detection mechanism for that into pantab :)

[vogelsgesang]

From Hyper's internal git log:

The commit [i.e., the change which broke this] also removes the redundant nullValues array from the hyper_rowset_chunk_field_values interface. The values are now simply nullptrs if they are null. Also, the hyper_rowset_chunk_field_values interface is now noexcept since it no longer allocates any memory.

So the check here can now be simplified quite nicely. Wouldn't be surprised if this also gives a nice performance boost to pantab.

We (i.e.: Tableau Hyper team) will see how we find time to contribute a fix for this. Expect to hear something within the next week(s). If somebody else finds time to fix this earlier, please go ahead. Happy to provide any advice/guidance/code reviews. In the meantime, your best option is to pin Hyper API at version 0.0.14401

[Btibert3]

Also just noticed this throwing install errors when using Google Colab, but pinning version to 0.0.14401 did the trick in the short run.

Still facing the same issue. Please help!

[vogelsgesang]

@rachwng It seems like your downgrade did not take effect as intended. I don't know anaconda, and don't know what could have gone wrong, but the error message raised by pantab still indicates that you are on a newer version of HyperAPI

[SarahBeth026]

I'm getting this error also, but slightly different

I have pantab v2.1.0 and tableauhyperapi v0.0.14751. I tried running pip install --force-reinstall tableauhyperapi==0.0.14401 --user and confirmed that it was using that version by running pip show tableauhyperapi| grep Version, but I'm still getting the same error. Any other ideas?

[WillAyd]

@SarahBeth026 are you sure the environment you are running pantab from is the same as the one with the tableauhyperapi you force reinstalled? Based off of what you’ve described I think those might be getting mixed up

[Carole-R]

Hello @WillAyd I've read your discussion under @vogelsgesang 's pull request and I would like to understand when the merger will take place? This would be greatly appreciated so that pantab runs smoothly for new users (i.e. working with the latest HyperAPI release).

[WillAyd]

@Carole-R looks like there are merge issues and outstanding comments on that PR. Is that something you would like to take over?

[Carole-R]

@WillAyd I'm a Python beginner for now. If @vogelsgesang wasn't able to go through the update, I don't think I'll be able to do better. I'll stick to pinning Hyper API at version 0.0.14401. Let's hope it won't slow new users from using Pantab (which is a very useful tool imo).
