Dependency resolution for `azure-core` failing due to transitive depdendencies

[tanertopal]

Describe the bug I am using Bazel with rules_python to generate a lock file for my dependencies. In the process of generating the lock file, I am encountering which you can see below.

farm-haystack dependents on azure-core<1.23 and some transitive dependencies on azure-core>=1.23.

Is this a known issue or does anyone know a fix?

There are incompatible versions in the resolved dependencies:

  azure-core<2.0.0,>=1.13.0 (from azure-ai-formrecognizer==3.2.0b2->farm-haystack[crawler,preprocessing]==1.6.0->-r third_party/py/requirements.in.txt (line 6))
  azure-core<1.23 (from farm-haystack[crawler,preprocessing]==1.6.0->-r third_party/py/requirements.in.txt (line 6))

Expected behavior

Transitive and direct dependencies should resolve correctly.

Additional context

• Using Bazel with rules_python

To Reproduce

1. Create a requirements.txt with the content:

farm-haystack[crawler,preprocessing]==1.6.0

2. Run

bazel run //third_party/py:requirements.update

Would it help if I created an example project?

@ZanSara could you help out here? This might be a known issue but I am unsure 😊

Hello @tanertopal, thank you for this report. So, we had issues in the past that lead us to the inclusion of a pin to azure-core<1.23 in the core dependencies. You can see the reason here:

https://github.com/deepset-ai/haystack/blob/408d8e6ff559ed0a195b68284baf3ab23707ffd7/setup.cfg#L71-L77

However, re-reading the reasoning of the comment and your issue, I realize the pin might be better added to the dev dependency group, where pydoc-markdown is required, rather than in the core dependencies list. Hopefully this will not cause mismatches between the development and the minimal dependency list: I will open a separate issue as a reminder for us to monitor the situation closely.

TL;DR: I will open a PR shortly and ask you to test if you can lock your dependencies using that branch.

Hey @tanertopal, please checkout #3022 and let me know if it helps. If we merge this PR this week it will be included in the next Haystack release on Monday :blush:

@ZanSara, I tried it out and its works and resolves my issue! Thank you for the fast turnaround!

[ZanSara]

Great, thanks for checking so quickly! It will be in master soon.
