ValueError: Misconfigured conditions in the pytorch_config: None. Valid examples:

Example: Using a bottom-up model for conditions
  
  data:
    conditions:
      config_path: /path/to/model-dir/pytorch_config.yaml
      snapshot_path: /path/to/model-dir/snapshot-best-150.pth
  
Example: Loading the predictions for snapshot-250.pt of shuffle 1.
  
  data:
    conditions:
      shuffle: 1
      snapshot: snapshot-250.pt
  
Example: Loading the predictions for the snapshot with index 2 of shuffle 1.
  
  data:
    conditions:
      shuffle: 1
      snapshot_index: 2
  

Example: Loading the predictions contained in an h5 file.
  
  data:
    conditions: /path/to/bu_predictions.h5
  
Example: Loading the predictions contained in an json file.
  
  data:
    conditions: /path/to/bu_predictions.json
