prefigure

0.0.10 verified Mon Apr 27 auth: no python

Run configuration management utilities combining configparser, argparse, and wandb.API. Version 0.0.10 is the latest; release cadence is sporadic.

pip install prefigure

Common errors

error AttributeError: 'Config' object has no attribute 'parse' ↓

cause Using version < 0.0.8 where parse was called differently.

fix

Upgrade to >=0.0.8: pip install --upgrade prefigure or use Config.parse() only in newer versions.

error ModuleNotFoundError: No module named 'wandb' ↓

cause wandb not installed but code tries to use wandb features.

fix

Install wandb: pip install wandb or disable wandb usage in config.

Warnings

gotcha The 'parse' method may overwrite defaults with command-line args; be careful about order of operations. ↓

fix Call cfg.parse() after setting defaults explicitly.

gotcha If wandb is not installed, the wandb integration fails silently; no error is raised. ↓

fix Install wandb if you need logging: pip install wandb

deprecated The 'wandb_api_key' parameter is deprecated in favor of environment variable WANDB_API_KEY. ↓

fix Set WANDB_API_KEY env var instead of passing it to Config.

Imports

Config

wrong

import prefigure; c = prefigure.Config()

correct

from prefigure import Config

Correct import is direct from module

prefigure
```
import prefigure
```
Module is small; simple import works

Quickstart

Create a Config object with defaults, then parse arguments.

from prefigure import Config
import os

# Define configuration
cfg = Config(
    defaults={
        'learning_rate': 1e-3,
        'batch_size': 32,
    },
    wandb_api_key=os.environ.get('WANDB_API_KEY', '')
)

# Parse command line arguments
cfg.parse()
print(cfg.learning_rate)
