I add a function(according the code in the tutorial4) to calculate the bleu score, but i get the vey low score(0.09), could you tell me why?
This is code to calculate bleu:

def translate_sentence(sentence, src_field, trg_field, model, device, max_len = 50):
    
    model.eval()
        
    if isinstance(sentence, str):
        nlp = spacy.load('de')
        tokens = [token.te

This is definitely a good implementation of the paper. As shown in the paper, it provides the visualization of the importance (attention) of each word in a document. I'm wondering, can we get the attention score for each word from the codes? Thank you so much!

• boolean flag for scrape_running() status

• save to raw_data_pipeline folder

• timezone basis/reference config (timezone of scrape)

• outline of function def for new hour of data (mock function)

• outline of error handling if scrape interrupted
