uploaded_sentence=" The issue of text semantics, such as word semantics and sentence semantics has received increasing attentions in recent years. However, rare research focuses on the document-level semantic matching due to its complexity. Long documents usually have sophisticated structure and massive information, which causes hardship to measure their semantic similarity. The semantic similarity between words, sentences, texts, and documents is widely studied in various fields, including natural language processing, document semantic comparison, artificial intelligence, semantic web, and semantic search engines.

在构建文件android studio中安装库：
在这个项目中，我们使用 chaquopy 在我们的 android 项目中使用 python，但它有一些问题，比如在导入库时我已经安装了 Nltk、wordnet、停止词和词标记化，但我无法访问这些库python 文件，如果我们安装我们的应用程序，它会崩溃。
if (! Python.isStarted()) {
Python.start(new AndroidPlatform(this));
Python py = Python.getInstance();
final PyObject pyobj = py.getModule("sum");
b2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (path==null) {
Toast.makeText(documentupload.this, " plz upload the doc", Toast.LENGTH_SHORT).show();
//upload.setText(path);
// Intent intent= new Intent(documentupload.this,result.class);
//startActivity(intent);
}
else {
PyObject obj = pyobj.callAttr("main", Words.toString());
upload.setText(obj.toString());
Toast.makeText(documentupload.this, "uploaded" + Words, Toast.LENGTH_LONG).show();
// Toast.makeText(documentupload.this, " plz upload the doc", Toast.LENGTH_LONG).show();
}
}
});
当应用程序崩溃时，它会给出以下错误消息：
【问题讨论】：
-
您的 Python 代码不包含名为
main的函数，因此不清楚 Java 和 Python 代码之间的联系是什么。请编辑您的问题以澄清这一点，并包括来自Logcat 的完整堆栈跟踪。 -
其实取消吧，我已经重现了这个问题，我会在几分钟后发布答案。
