Fix computation of num_inputs for Python API create_operator_entry fo…

…r custom operators with 0 arguments.

This is the same change as in #7967 but against v0.11.0 branch.

Will this be built to Pypi package index automatically?

We will need to manually tag a release to get it built and released on pypi.

[fhieber]

We'd appreciate this a lot :)

@szha @piiswrong What's the process to get this into a pypi release or who should we contact for this?

[szha]

I pinged others offline and the POC for coordinating a release is @mbaijal.

Another item that came up was whether to patch 0.11.0 as post-release or release a new 0.11.1. Do you foresee any problem of getting onto 0.11.1?

[fhieber]

Thanks!

Actually, 11.1 / master has some nice features we would like to use asap (non-flattening FullyConnected, support for 2d input data to Sequence* operators) so we could directly upgrade to 11.1 if its released soon.

Important is the timeline for this as we currently are officially depending on 0.10.0 and the Mac pypi package seems to be removed from the index. Some people might be blocked to use Sockeye on a mac for that reason. And until 11.* pypi packages do not contain my fix, our travis builds will keep failing.

So whatever release is easier and faster would be currently preferable, but we plan upgrade to later releases faster in the future.

[szha]

I see. @mbaijal please coordinate and come up with a timeline.

@fhieber a channel for quick integration testing is through nightly pip-release, which can be obtained through turning on --pre flag when doing pip install, just to make sure you're aware.

[fhieber]

That's good to know, thank you!

@mbaijal any news on the timeline? :)

[mbaijal]

@tdomhan
Apologies for the delay in my response. The team is currently in discussions regarding the next release and I will update you as soon as we have a final timeline (I believe it should be sometime in October). In the meantime, is it possible for you to continue to use the master branch?

[tdomhan]

thanks for the update! Do you mean that 11.1 will be released some time in October, or that a patched version of 11.0 will be released by then?
