ValueError: 'early_stopping' must be a boolean or 'never', but is None.

This error happened even after implementation of :

class Canary(object):
    def __init__(self):
        canary_dir = download(DATA_DIR)
        canary_meta_data = os.path.join(canary_dir, 'model.opt')
        with open(canary_meta_data) as f:
            opt = json.load(f)
        **opt['early_stopping'] = False  # 'never' doesn t work neither**

        opt['skip_generation'] = False
        opt['model_file'] = os.path.join(canary_dir, 'model')
        self.agent = create_agent(opt)

This might due to installing the newer version of transformers library.
My solution is update transformers and Parlai to the latest. (transformer==4.46.3 ,parlai==1.7.2)
Still working on it, making sure that everything goes as plan.
