Dvc fails due to outs stage entry

Questions
1

Hi,
I cannot run dvc due to the following error:
ERROR: failed to reproduce ‘dvc.yaml’: output ‘…/data-registry/forecast/models’ does not exist

I already tried different paths, relative, absolute and using direclty the paths instaed of using it by params var. :confused:
The weird thing is that this already worked. And suddently stops working.
I already use dvc destroy to clean everthing and I starded again and the problems continues :confused:

Can someone help me?
thanks

My dvc.yaml is:

vars:
  - db_config_file: /home/dsmendes/Documents/implementation/forecasting_module/config/config.yaml
  - params_file: /home/dsmendes/Documents/implementation/forecasting_module/params.yaml

stages:
  train:
    wdir: ..
    cmd: python -m forecasting_module.pipeline train ${db_config_file} ${params_file}
    params:
      - ${params_file}:
        - common.paths.models
        - common.columns.id
        - common.columns.date
        - common.columns.value
        - prophet.columns.prophet_date
        - prophet.columns.prophet_value
        - prophet.train_parameters.seasonality_mode
    outs:
      - ${common.paths.models}

The debug outputs is:

The error message means that DVC thinks your stage failed because the specified out was not actually generated.

Does the directory ../data-registry/forecast/models exist after you’ve run the train stage?

Also double check that your relative paths (specifically the common.paths.models parameter) are correct, DVC will interpret them relative to <dir containing dvc.yaml>/…since you have also definedwdir: …` in your stage.

Thanks you.
I found my error. I had a mistake into my code. And the outs was not created.
