How to set config properly to launch an experiment on wk103 (of any model)?

[Chord-Chen-30]

I run the command

python train.py wandb.mode=offline experiment=wt103/base pipeline=wt103

from safari/ directory and the program gives:

Error executing job with overrides: ['wandb.mode=offline', 'experiment=wt103/base', 'pipeline=wt103']
Traceback (most recent call last):
  File "/public/home/chenzhuo/cz/safari/train.py", line 679, in main
    config = utils.train.process_config(config)
  File "/public/home/chenzhuo/cz/safari/src/utils/train.py", line 69, in process_config
    config = omegaconf_filter_keys(config, lambda k: not k.startswith('__'))
  File "/public/home/chenzhuo/cz/safari/src/utils/config.py", line 121, in omegaconf_filter_keys

  File "/public/home/chenzhuo/cz/safari/src/utils/config.py", line 121, in <dictcomp>

    full_key: dataset.cache_dir
    object_type=dict

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.

Then I add HYDRA_FULL_ERROR=1 :

My questions are:

1. Am I using the config correctly? If not, how to set the config?
2. What does the output mean?

[Zymrael]

You should set a DATA_PATH environment variable: export DATA_PATH=/your/path/.

[Chord-Chen-30]

Thank you for the reply. It seems to fix the problem. However, I am confused about the statement in safari/src/dataloaders/README.md.

In Overview:
By default, data is downloaded to ./data/ by default, ...

In Advanced Usage:
The data path can be configured by setting the environment variable DATA_PATH, which defaults to ./data

Why the default setting is not applied (and we need to explictly set DATA_PATH).
