Configuration

Every ForecastModel stage auto-captures its kwargs into a ForecastConfig object, which can be saved to YAML/JSON and replayed via from_config() → run(). This page covers config persistence, the dataclass layout, Telegram notifications, and runtime logging.

         fm.save_config()         ForecastModel.from_config(path)
         → forecast.config.yaml   → new ForecastModel
                                  → fm.run() replays each non-None section

A stage that hasn't run yet is None in the YAML - the produced config is "partial" and can be loaded + continued.
fm.evaluate(...) calls save_config() automatically before returning. Call it manually at earlier points to checkpoint a partial pipeline.

Default path

{station_dir}/forecast.config.yaml      # fm.save_config()
{station_dir}/forecast.config.json      # fm.save_config(fmt="json")

{station_dir} = {output_dir}/{network}.{station}.{location}.{channel} - sibling of the per-stage cache/ directories.

Round-trip

fm.save_config("output/config.yaml")
fm2 = ForecastModel.from_config("output/config.yaml")
fm2.run()    # idempotent - replays every captured stage

ForecastExplainConfig fields

Field	Type	Default	Notes
`model`	`Literal["training", "prediction"]`	`"prediction"`	Which upstream stage to explain
`eruption_dates`	`list[str] \| None`	`None`	Falls back to `train()` dates at replay
`save_per_seed`	`bool`	`True`	Persist `shap_values/{seed:05d}.pkl` per seed
`plot_per_seed`	`bool`	`True`	Bar + beeswarm per seed under `classifiers/{Clf}/figures/`
`figsize`	`tuple[float, float] \| None`	`None`	Auto-sized when `None`
`max_display`	`int`	`20`	tsfresh labels truncated to this many in plots
`group_remaining_features`	`bool`	`False`	Forwarded to `shap.plots.beeswarm`
`dpi`	`int`	`150`	Figure resolution
`check_additivity`	`bool`	`False`	Forwarded to `shap.TreeExplainer`
`overwrite_classifier_explanation`	`bool`	`False`	Overwrite cached `ClassifierExplanation_*.pkl`
`output_dir`	`str \| None`	`None`	Inherits from `ForecastModel`
`overwrite`	`bool \| None`	`None`	Inherits from `ForecastModel`
`n_jobs`	`int \| None`	`None`	Inherits from `ForecastModel`
`verbose`	`bool \| None`	`None`	Inherits from `ForecastModel`

`None`-as-inherit

For overwrite, n_jobs, and verbose, a YAML value of null means "inherit the value ForecastModel.__init__ was constructed with". This is the same semantics applied at runtime when the kwarg is omitted, so a replay behaves identically.

TrainingConfig (Standalone)

TrainingModel.__init__ captures its own kwargs into a TrainingConfig dataclass (config/training_config.py), independent of ForecastConfig. Use this when you run TrainingModel outside of ForecastModel:

tm.save_config()      # → {output_dir}/training.config.yaml

The shape mirrors the TrainingModel.__init__ signature - see Training Workflow.

`config.example.yaml`

A fully annotated example config ships at the repo root: config.example.yaml. Project Rule 11 keeps it in sync with forecast_config.py - when any ForecastConfig field is added, renamed, or has its default changed, the example YAML is updated in the same commit.

Telegram Notifications

eruption_forecast.decorators exposes two complementary primitives.

`notify` decorator

Wraps a function to send a Telegram message on success or failure:

from eruption_forecast import notify
import dotenv; dotenv.load_dotenv()

@notify("Run Forecasting")
def main():
    fm = ForecastModel(...)
    fm.calculate(...).train(...).predict(...).evaluate(...)

main()    # Telegram chat receives start, finish, and error messages

`send_telegram_notification(...)` helper

Used by scenarios.py to ship the per-scenario forecast plot:

from eruption_forecast import send_telegram_notification

send_telegram_notification(
    message=f"{name}: {description}",
    files=[fm.PredictionModel.forecast_plot_path],
    file_caption=f"{name}: {description}",
    send_as_document=True,        # preserves DPI - Telegram does not re-encode
)

Credentials (`.env`)

TELEGRAM_BOT_TOKEN=your_bot_token_here
TELEGRAM_CHAT_ID=your_chat_id_here

Bot token from @BotFather
Chat ID from @userinfobot

Both primitives degrade gracefully when the env vars are absent - they emit a warning and skip the network call instead of raising.

Logging

The package wraps loguru behind eruption_forecast.logger.

Function	Purpose
`enable_logging()`	Restore console + file handlers using the current log directory
`disable_logging()`	Remove every active loguru handler - no console, no file
`set_log_level(level)`	Change the console handler level (`"DEBUG"` / `"INFO"` / `"WARNING"` / `"ERROR"` / `"CRITICAL"`)
`set_log_directory(dir)`	Move the log file to a new directory - created if missing

from eruption_forecast import enable_logging, disable_logging
from eruption_forecast.logger import set_log_level, set_log_directory

set_log_directory("logs/2026-06-10")
set_log_level("DEBUG")        # console only - file handlers keep their level

disable_logging()
fm.calculate(...)             # silent - useful during tests
enable_logging()              # restore handlers

enable_logging, disable_logging, notify, and send_telegram_notification are exported from the package root.

Where Configuration Lives in the Filesystem

The *.params.json files inside cache/ capture exactly what went into the cache hash. They are handy when debugging a cache miss - diff two of them to see which kwarg differed.
