url download error

[jjxyai]

device env: win10 py3.8
found in my env, when downloading yaml and pyth, raise "urllib.error.HTTPError: HTTP Error 404: Not Found",

it turned out that when concat url,

config_url = os.path.join(_URL_CONFIGS, _MODEL_ZOO_CONFIGS[name])

the sep added in the url in windows is '', which cause this error,

to solve in my env:
config_url = _URL_CONFIGS + '/ + _MODEL_ZOO_CONFIGS[name]
or as implemented in https://stackoverflow.com/questions/8223939/how-to-join-absolute-and-relative-urls
