# Two lists of sentences
sentences1 = ['The cat sits outside',

             'The new movie is awesome']

sentences2 = ['The dog plays in the garden',

              'The new movie is so great']

#Compute embedding for both lists

embeddings1 = model.encode(sentences1, convert_to_tensor=True)
embeddings2 = model.encode(sentences2, convert_to_tensor=True)

#Compute cosine-similarities
cosine_scores = util.cos_sim(embeddings1, embeddings2)

#Output the pairs with their score
for i in range(len(sentences1)):

我遇到了这个错误

JsException(PythonError: Traceback (最近调用最后一次): 文件“/lib/python3.10/site-packages/_pyodide/_base.py”, 第 429 行，在 eval_code .运行(globals, locals) File "/lib/python3.10/site-packages/_pyodide/_base.py", 第 300 行，在运行 coroutine = eval(self.code, globals, locals) File " “，第 1 行，在 ModuleNotFoundError 中：没有名为 'sentence_transformers' )

的模块

Answer 1

sentence_transformers 不是 Python 标准库中内置的模块，因此您需要安装它。根据documentation, you do that by adding the package name到py-env元素：

<py-env>
- sentence-transformers
</py-env>

但是，目前看来 sentence-transformers 并不是 available in pyodide。您可以打开一个 PR 或问题来添加它。
