将Java的gensim python与jython结合使用

Question

我想在python代码中使用gensim库，并且需要从Java执行该代码。

以下是python代码，send2vec.py：

import gensim
sentences = gensim.models.doc2vec.LabeledLineSentence('/tmp/sentence.tmp')
model = gensim.models.doc2vec.Doc2Vec(sentences, size=10, window=5, min_count=2, workers=4)
model.save_word2vec_format('/tmp/sentenceVectors.txt')

代码在独立模式下运行良好，即，当由以下人员执行时：

python sent2vec.py

但是我需要从Java代码中调用此函数。我尝试使用Jython，但出现错误。我的Java代码如下所示：

StringWriter writer = new StringWriter(); //output will be stored here
ScriptEngineManager manager = new ScriptEngineManager();
ScriptContext context = new SimpleScriptContext();

context.setWriter(writer); //configures output redirection
ScriptEngine engine = manager.getEngineByName("python");
engine.eval(new FileReader("sent2vec.py"), context);
System.out.println(writer.toString());

我遇到此错误：
