hydra error when running the train.py code

[plentyluckman]

Hi, first of all , thanks for your team's great work.

I am having trouble running CAPE training code provided by readme.md

  File "C:\Users\mms312\anaconda3\envs\snarf_env\lib\site-packages\hydra\_internal\instantiate\_instantiate2.py", line 180, in instantiate
    return instantiate_node(config, *args, recursive=_recursive_, convert=_convert_)
  File "C:\Users\mms312\anaconda3\envs\snarf_env\lib\site-packages\hydra\_internal\instantiate\_instantiate2.py", line 266, in instantiate_node
    cfg[key] = instantiate_node(
  File "C:\Users\mms312\anaconda3\envs\snarf_env\lib\site-packages\hydra\_internal\instantiate\_instantiate2.py", line 245, in instantiate_node
    value = instantiate_node(
  File "C:\Users\mms312\anaconda3\envs\snarf_env\lib\site-packages\hydra\_internal\instantiate\_instantiate2.py", line 249, in instantiate_node
    return _call_target(_target_, *args, **kwargs)
  File "C:\Users\mms312\anaconda3\envs\snarf_env\lib\site-packages\hydra\_internal\instantiate\_instantiate2.py", line 64, in _call_target
    raise type(e)(
  File "C:\Users\mms312\anaconda3\envs\snarf_env\lib\site-packages\hydra\_internal\instantiate\_instantiate2.py", line 62, in _call_target
    return _target_(*args, **kwargs)
TypeError: Error instantiating 'lib.dataset.cape.CAPEDataProcessor' : __init__() missing 2 required positional arguments: 'opt' and 'meta_info'

and this msg is produced when I run

 python train.py datamodule=cape subject=3375 +datamodule.clothing='blazerlong' +experiments=cape  

I put + right before datamodule.clothing argument on purpose, which is different from the guide on readme.md; otherwise, it gave different error like:

omegaconf.errors.ConfigAttributeError: Key 'clothing' is not in struct
    full_key: datamodule.clothing
    object_type=dict

I think datamodule = hydra.utils.instantiate(opt.datamodule, opt.datamodule) in train.py part gave this error.

If I train on AMASS it also produces similar error

python train.py subject=50002

then

Any thought or idea on this?
Thanks,

Hi @plentyluckman,

it could be caused by different hydra versions - hydra API changes very quickly.

Could you let me know which version of hydra are you currently using? Also if it's not hydra-core==1.0.6, could you try 1.0.6 instead?

[plentyluckman]

@xuchen-ethz

yes, you are right.
The error not showing up anymore, after downgrading the hydra-core version (from 1.1.0 to 1.0.6)

Thank you

[xuchen-ethz]

great :)
