ValueError: [E024] 找不到监督解析器的最佳动作

Question

spacy使用自定义训练数据训练NER 模型时出现以下错误。

ValueError: [E024] Could not find an optimal move to supervise the parser. Usually, this means the GoldParse was not correct. For example, are all labels added to the model?

谁能帮我这个？

通过下面的这个函数传递训练数据工作正常，没有任何错误。

def trim_entity_spans(data: list) -> list:
    """Removes leading and trailing white spaces from entity spans.

    Args:
        data (list): The data to be cleaned in spaCy JSON format.

    Returns:
        list: The cleaned data.
    """
    invalid_span_tokens = re.compile(r'\s')

    cleaned_data = []
    for text, annotations in data:
        entities = annotations['entities']
        valid_entities = []
        for start, end, label in entities:
            valid_start = start
            valid_end = end
            while valid_start < len(text) and invalid_span_tokens.match(
                    text[valid_start]):
                valid_start += 1
            while valid_end > 1 and invalid_span_tokens.match(
                    text[valid_end - 1]):
                valid_end -= 1
            valid_entities.append([valid_start, valid_end, label])
        cleaned_data.append([text, {'entities': valid_entities}])

    return cleaned_data
