kraken-models's Issues

forward() missing 1 required positional argument: 'hidden' when using en-default.pronn

I tried to use en-default.pronn from the repository with the command kraken -i Screenshot2.png screenshot.txt binarize segment ocr -m en-default.pronn but I got the following error :

Kraken can't get default

Hello,

When running kraken get default I have the following error:

    logger.error('Found {} models when querying for id \'{}\''.format(model_id))
IndexError: tuple index out of range

On another note, kraken list doesn't return the usual list but this instead:

kraken list

Error with kraken get default

When trying to get the default model I receive the following error:

    obj, end = self.scan_once(s, idx)

Any ideas on how to get around that?

Kraken can't access the model repository return 'API rate limit error'

Just ran kraken get default after installing and when I tried to download another model a couple of minutes after I got the following error:

kraken list return the same error.
