Question

我第一次尝试基于这个模型使用变形金刚：

https://huggingface.co/bhadresh-savani/distilbert-base-uncased-emotion?text=I+like+you.+I+love+you

此处提供的示例代码其：

from transformers import pipeline
classifier = pipeline("text-classification",model='bhadresh-savani/distilbert-base-uncased-emotion', return_all_scores=True)
prediction = classifier("I love using transformers. The best part is wide range of support and its easy to use", )
print(prediction)

但是我得到这个错误：

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)
<ipython-input-6-74ca6189abbe> in <module>

----> 2 classifier = pipeline("text-classification",model='bhadresh-savani/distilbert-base-uncased-emotion', return_all_scores=True)
      3 prediction = classifier("I love using transformers. The best part is wide range of support and its easy to use", )
      4 print(prediction)

    237         f"Unknown task {task}, available tasks are {list(SUPPORTED_TASKS.keys()) + ['translation_XX_to_YY']}"
    238     )

KeyError: "Unknown task text-classification, available tasks are ['feature-extraction', 'sentiment-analysis', 'ner', 'question-answering', 'table-question-answering', 'fill-mask', 'summarization', 'translation', 'text2text-generation', 'text-generation', 'zero-shot-classification', 'conversational', 'translation_XX_to_YY']"

是的，我先安装了变压器

您从他们的文档中引用的示例似乎已过时。 text-classification 管道已重命名为 sentiment-analysis，因此您需要替换：

classifier = pipeline("text-classification"...

与：

classifier = pipeline("sentiment-analysis"...

如果您想阅读更多相关信息，请点击此处link to the pipeline docs。

未知任务文本分类，可用任务有['feature-extraction', 'sentiment-analysis',
