Ubuntu 22.04 Python 3.11 [asr]: multiple errors `dataclasses ValueError: mutable default * for field * is not allowed: use default_factory` #7166

Describe the bug

After installing latest stable 1.19.1 from pipI, or the latest current commit with [asr] extras, I'm getting this error from hydra-core==1.2.0 when trying to import nemo.collections.asr:

It's easy to fix with a patch like this:

This can also be fixed accordingly, but all in all, it appears these issues are pretty common in the code base.

Looks like NeMo isn't Python 3.11 ready, at least the asr collection.

Steps/Code to reproduce bug

With Python 3.11

Install nemo-toolkit[asr] either 1.19.1, or current HEAD from git (b498d43)
Run import nemo.collections.asr

Expected behavior

Import nemo.collections.asr without errors

Environment overview (please complete the following information)

Environment location: Bare-metal
Method of NeMo install: pip install nemo-toolkit==1.19.1 or from source b498d43

Environment details

Ubuntu 22.04
PyTorch version 2.0.1
Python version 3.11.4

Seems to be a similar to #7002

titu1994 · 2023-08-04T16:45:31Z

Interesting. The fix is easy but needs to be applied to basically every single place that has this constructor for our adapter configs. Let me see if I can update it. But no guarantees on how soon fixes will come in main.

alllexx88 · 2023-08-04T20:58:21Z

Looking forward to it @titu1994 ! Thanks 😃

@titu1994 I was looking to use NeMo speaker diarization with Python 3.11 and hit this dataclass issue. I patched everything involved in the specific code paths I needed: lmnt-com@d89acf9

I was using the neural diarizer as described in https://github.com/NVIDIA/NeMo/tree/main/examples/speaker_tasks/diarization

I'd be happy to upstream this if it's helpful.

I haven't checked whether this is backwards compatible for earlier python/dataclass versions, do you know?

For reference, what led me to this issue, though it's duplicative to the above discussion:

@shaper Thanks for sharing. For brevity, you don't really need a lambda when you don't pass any init parameters, like this:

field(default_factory=lambda: ConfidenceConfig())

You can just do

field(default_factory=ConfidenceConfig)

It's only needed when you do pass parameter(s), like

field(default_factory=lambda: beam_decode.BeamRNNTInferConfig(beam_size=4))

    ValueError: mutable default <class 'nemo.core.classes.mixins.adapter_mixin_strategies.ResidualAddAdapterStrategyConfig'> for field adapter_strategy is not allowed: use default_factory

For documentation (I had to search in the provided links):
Mutable defaults were never allowed in dataclasses (by convention), but in python 3.11 they improved the check: Instead of checking some types (dict, list, set) they now use hashable as indicator for mutable.

An alternative to default_factory would be to use frozen dataclasses, but I don't know whether in this code base the configs are used as mutable objects or not.

You need to update to NeMo 1.20, omegaconf did a fix that should resolve this
