首先是安装python,更新pip源到清华源。安装transformer
pip install transformer
安装jupyter lab,也简单一行
pip install jupyterlab
现在不想用anaconda了,因为国内没有源了,国外的又慢。直接用pip吧。
然后开始体验之旅吧:
打开终端,输入:
jupyter lab
会弹出一个web页面,代开后输入python代码:
from transformers import pipeline cf = pipeline("sentiment-analysis") cf( ["hello world.", "This place is too dirty.", ] )
输出下面的内容:
No model was supplied, defaulted to distilbert-base-uncased-finetuned-sst-2-english and revision af0f99b (https://huggingface.co/distilbert-base-uncased-finetuned-sst-2-english). Using a pipeline without specifying a model name and revision in production is not recommended.(这里是一个警告,没关系) [{'label': 'POSITIVE', 'score': 0.9997791647911072}, {'label': 'NEGATIVE', 'score': 0.999772846698761}]
输出包含了这两句话的正面还是负面情绪的判断。可以自己写两句看看哦。
注意:代码最后一段的是调用cf,所以没有“=”号,要注意,我一开始就是多添加一个“=”,半天看不出哪里错了。
