Thanks for your contribution. But why we need download a checkpoint from remote GitHub.

@zhouzaida because model_zoo.yml file may not be available at local.

got it

Got it. Please add an unittest. Another thing is that the config file can not be successfully obtained from remote because the config is parsed from the local repo.

@zhouzaida it is also an issue. wheel package of mmdetection does not include configs directory and mim gives an error when trying to load config from local. I have created a separate issue for that: #50

[fcakyon]

@zhouzaida added tests for model_info_local=False.

hi @fcakyon , the following lines should be moved. In addition, we download checkpoints and configs by default so we can provide two options to only download one of them

mim/mim/commands/download.py

Lines 63 to 71 in eb35cce

	if version:
	raise ValueError(
	highlighted_error('version is not allowed, please type '
	'"mim download -h" to show the correct way.'))
	if not is_installed(package):
	raise RuntimeError(
	highlighted_error(f'{package} is not installed. Please install it '
	'first.'))
