"RecursionError: maximum recursion depth exceeded in comparison" while training new model

[jistiak]

I am trying to train a new model with the latest release v3.3.0 of Myria3D. But I am always getting this recursion error generating from Hydra. It looks like this-

RecursionError: maximum recursion depth exceeded in comparison

I followed the instructions from dataset preparation and train new models sections and still having this issue. Previously I have tried the toy_dataset as well as trained new model with previous versions of Myria3D without any issues.

I found out from here that this might happen if the config somehow loads itself. But I could not figure out which config file might have caused this.

Any suggestions on how to fix it? Thanks :)

System: Ubuntu 22.04 Python: 3.9.16 hydra version: 1.1.2

Hi @jistiak, thank you for pointing to the origin of this error: I was able to find the culprit in the base training configuration.

I just merged a fix (see https://github.com/IGNF/myria3d/pull/61) and you may use V3.3.1 :)

[CharlesGaydon]

Out of curiosity: are you using in-house data or working on public aerial Lidar datasets? I would love to hear more about your use case (Discussions might be a great place to Show and Tell!) 😃

@CharlesGaydon Thanks a lot for addressing the issue so quickly. It solved the problem 😃

As of now, I am using public lidar datasets. If I manage to do anything worthwhile, I would definitely love to discuss it in Show and Tell 😃

You are very welcome. Lovely! Closing this issue :)
