Nixtla Experiment Architect
Design and scaffold complete forecasting experiments using Nixtla's libraries.
Overview
This skill creates production-ready experiment harnesses:
- Configuration management: YAML-based experiment config
- Multi-model comparison: StatsForecast + MLForecast + TimeGPT
- Cross-validation: Rolling-origin or expanding-window
- Metrics evaluation: SMAPE, MASE, MAE, RMSE
Prerequisites
Required:
- Python 3.8+
statsforecast, utilsforecast
Optional:
mlforecast: For ML modelsnixtla: For TimeGPTNIXTLA_API_KEY: TimeGPT access
Installation:
pip install statsforecast mlforecast nixtla utilsforecast pyyaml
Instructions
Step 1: Gather Requirements
Collect experiment parameters:
- Data source path
- Target column name
- Forecast horizon (e.g., 14 days)
- Frequency (D, H, W, M)
- Unique ID column (optional)
Step 2: Generate Configuration
python {baseDir}/scripts/generate_config.py \
--data data/sales.csv \
--target sales \
--horizon 14 \
--freq D \
--output forecasting/config.yml
Step 3: Scaffold Experiment
python {baseDir}/scripts/scaffold_experiment.py \
--config forecasting/config.yml \
--output forecasting/experiments.py
Step 4: Run Experiment
python forecasting/experiments.py
Step 5: Review Results
cat forecasting/results/metrics_summary.csv
Output
- forecasting/config.yml: Experiment configuration
- forecasting/experiments.py: Runnable experiment harness
- forecasting/results/: Metrics and forecasts (after running)
Error Handling
-
Error: Data file not found
Solution: Verify data source path in config
-
Error: Column not found
Solution: Check column names match your data
-
Error: Missing required package
Solution: Install missing dependencies with pip
-
Error: Cross-validation failed
Solution: Ensure enough data for n_windows
Examples
Example 1: Daily Sales Forecast
python {baseDir}/scripts/generate_config.py \
--data data/sales.csv \
--target revenue \
--horizon 30 \
--freq D \
--id_col store_id
Output config.yml:
data:
source: data/sales.csv
target: revenue
unique_id: store_id
forecasting:
horizon: 30
freq: D
models:
- SeasonalNaive
- AutoETS
- AutoARIMA
Example 2: Hourly Energy Forecast
python {baseDir}/scripts/generate_config.py \
--data data/energy.csv \
--target consumption \
--horizon 24 \
--freq H
