Breaking changes

Control when to write DVC configuration file (dvclive/dvc.yaml)

• Add dvcyaml keyword argument to Live() (default: True) to control when to write dvclive/dvc.yaml, which configures how DVC shows metrics, plots, and parameters #443. Previously, DVCLive determined implicitly whether to write dvclive/dvc.yaml.
• Add Live.make_dvcyaml() method to write dvclive/dvc.yaml #443.
• Live() will no longer remove dvclive/dvc.yaml #440.

Example:

from dvclive import Live
live = Live()
live.log_param("lr", 0.01)
live.log_metric("acc", 0.9)
live.log_sklearn_plot("confusion_matrix", [0, 0, 1, 1], [1, 0, 0, 1])
live.next_step()

By default, live.next_step() calls live.make_dvcyaml(), which writes DVC configuration to dvclive/dvc.yaml:

params:
  - params.yaml
metrics:
  - metrics.json
plots:
  - plots/metrics
  - plots/sklearn/confusion_matrix.json:
      template: confusion
      x: actual
      y: predicted
      title: Confusion Matrix
      x_label: True Label
      y_label: Predicted Label

If you are already tracking DVCLive metrics, plots, and parameters in your own
dvc.yaml file, set Live(dvcyaml=False) to avoid duplication.

Allow overwriting data

• Stop throwing errors if data was already logged for a step #445

Example:

from dvclive import Live
live = Live()
live.log_metric("acc", 0.9)
live.log_metric("acc", 0.95) # previously would have raised an error

Shorten field names

• Shorten path-separated names in metrics history files and plots #444

Example:

from dvclive import Live
live = Live()
live.log_metric("train/epoch/acc", 0.9)

This will generate a metrics history file at dvclive/plots/metrics/train/epoch/acc.tsv with the field acc. Previously, the field would be train/epoch/acc, duplicating the path name and resulting in lengthy plots legends.
