我想创建自己的 spacy 训练模型。使用我的以下代码，我收到错误。

TRAIN_DATA = [
    ("Uber blew through $1 million a week", [(0, 4, 'ORG')]),
    ("Android Pay expands to Canada", [(0, 11, 'PRODUCT'), (23, 30, 'GPE')]),
    ("Spotify steps up Asia expansion", [(0, 8, "ORG"), (17, 21, "LOC")]),
    ("Google Maps launches location sharing", [(0, 11, "PRODUCT")]),
    ("Google rebrands its business apps", [(0, 6, "ORG")]),
    ("look what i found on google!", [(21, 27, "PRODUCT")])]

nlp = spacy.blank("en")
optimizer = nlp.begin_training()
for i in range(20):
    random.shuffle(TRAIN_DATA)
    for text, annotations in TRAIN_DATA:
        nlp.update([text], [annotations], sgd=optimizer)
nlp.to_disk("/model")

我收到以下错误，当我在此站点https://spacy.io/usage/training上使用简单的训练循环时，我没有得到它的工作原理

输出：

    508         grads = {}

--> 478                     raise ValueError(err)
    479                 gold = GoldParse(doc, **gold)
    480             doc_objs.append(doc)

ValueError: [E151] Trying to call nlp.update without required annotation types. Expected top-level keys: ('words', 'tags', 'heads', 'deps', 'entities', 'cats', 'links'). Got: [(0, 11, 'PRODUCT')].

谁能帮助我为什么会收到此错误？

我认为这应该解决它：

from spacy.gold import GoldParse  #<--- add this

...
for i in range(20):
    random.shuffle(TRAIN_DATA)
    for text, annotations in TRAIN_DATA:
        text = nlp.make_doc(text)    #<--- add this
        gold = GoldParse(text, entities=annotations)  #<--- add this
        nlp.update([text], [gold], sgd=optimizer)
