imp module is deprecated in python3

[makortel]

(kind of continuation of https://github.com/cms-sw/cmssw/issues/34489)

The imp module is deprecated in python3, and its use leads to a warning printout

 DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
  import imp

The following files import imp https://github.com/cms-sw/cmssw/blob/393dfc8c101a1cb66d516875657023569c8277bb/Alignment/HIPAlignmentAlgorithm/scripts/batchHippy.py#L5 https://github.com/cms-sw/cmssw/blob/393dfc8c101a1cb66d516875657023569c8277bb/CalibMuon/DTCalibration/python/Workflow/Crabtools/crabFunctions.py#L11 https://github.com/cms-sw/cmssw/blob/393dfc8c101a1cb66d516875657023569c8277bb/PhysicsTools/Heppy/python/utils/cmsswPreprocessor.py#L5 https://github.com/cms-sw/cmssw/blob/393dfc8c101a1cb66d516875657023569c8277bb/PhysicsTools/Heppy/test/crab/heppy_crab_script.py#L25 https://github.com/cms-sw/cmssw/blob/393dfc8c101a1cb66d516875657023569c8277bb/PhysicsTools/HeppyCore/python/framework/heppy_loop.py#L11 https://github.com/cms-sw/cmssw/blob/393dfc8c101a1cb66d516875657023569c8277bb/PhysicsTools/HeppyCore/python/framework/looper.py#L9 https://github.com/cms-sw/cmssw/blob/393dfc8c101a1cb66d516875657023569c8277bb/PhysicsTools/HeppyCore/scripts/heppy_batch.py#L6

hi @arizzi, @gpetruc is Heppy still used for anything? I see updates that are back to like 6 years ago. If it's not used at all, maybe we should consider removing the package?

The import imp will fail in Python 3.12.

[mmusich]

+hlt

• https://github.com/cms-sw/cmssw/pull/46164 removed the files importing imp

+analysis

• fixed in https://github.com/cms-sw/cmssw/pull/46172

[smuzaffar]

https://github.com/cms-sw/cmssw/pull/46707 should fix FWCore/ParameterSet/python/TreeCrawler.py
