I am trying to alter an existing framework having 18 flags to have 2 more flags. Every single time I try to use the flag, it says that the flag is not existing.

class Config(object):
    def __init__(self):
        self.cv_data: Optional[List[pd.DataFrame]] = None
        self.cv_labels: Optional[pd.DataFrame] = None

        self.train_labels: Optional[pd.DataFrame] = None
        self.test_data: Optional[List[pd.DataFrame]] = None
        self.test_labels: Optional[pd.DataFrame] = None
        self.classes: Optional[Set[int]] = None
        self.num_classes: Optional[int] = None
        self.ts_length: Optional[int] = None
        self.variate: Optional[int] = None
        self.strategy: Optional[str] = None
        self.timestamps: Optional[List[int]] = None
        self.folds: Optional[int] = None

        self.java: Optional[bool] = None
        self.file: Optional[click.File] = None
        self.splits: Optional[dict] = None
        self.make_cv: Optional[bool] = None
        self.realtime: Optional[bool] = None
        self.interval: Optional[int] = None

def cli(config: Config,

    # Store generic parameters
    config.variate = variate
    config.strategy = strategy
    config.folds = folds
    config.target_class = target_class
    config.output = output
    config.java = java
    config.cplus = cplus
    config.splits = None
    config.make_cv = make_cv
    config.interval = interval
    config.realtime = realtime

That is the given code. I tried to "realtime" and "interval".

Every time I try to run the programme using --interval or --realtime, I get the error

Error: no such option: --interval

However, if I run the --help command, the commands are actually listed.

Is there anything I am doing wrong?

CodePudding user response:

click groups with subcommands are picky about argument ordering. Since what you're attempting to modify is indeed a Click group, you'll need to pass --interval before the subcommand name.

A simplified example:

import click
import dataclasses


@dataclasses.dataclass
class Config:
    interval: int = 0


pass_config = click.make_pass_decorator(Config, ensure=True)


@click.group()
@click.option('--interval', default=1)
@pass_config
def cli(config, interval):
    config.interval = interval


@cli.command()
@click.option('--toughness', default=8)
@pass_config
def mangle(config, toughness):
    print(f"Mangling at {config.interval} interval and {toughness} toughness")


if __name__ == '__main__':
    cli()

Passing --interval after mangle: no go.

$ python3 so73649041.py mangle --interval=8
Usage: so73649041.py mangle [OPTIONS]
Try 'so73649041.py mangle --help' for help.

Error: No such option: --interval

Passing --interval before mangle: go.

$ python3 so73649041.py --interval=3 mangle
Mangling at 3 interval and 8 toughness

Passing a subcommand's option before its name: no go.

$ python3 so73649041.py --toughness=7 mangle
Usage: so73649041.py [OPTIONS] COMMAND [ARGS]...
Try 'so73649041.py --help' for help.

Error: No such option: --toughness

Passing everything: go.

$ python3 so73649041.py --interval=42 mangle --toughness=110
Mangling at 42 interval and 110 toughness
