我想使用 GloVe 嵌入英语句子。训练时显示错误“java.lang.RuntimeException：java.lang.UnsupportedOperationExceptionat”

手套嵌入是将英文文本编码为向量的无监督模型。Dl4j 是一个 java 库。在训练 Glove 模型时，会出现此错误。

File inputFile = new ClassPathResource("raw_sentences.txt").getFile();

    // creating SentenceIterator wrapping our training corpus
    SentenceIterator iter = new BasicLineIterator(inputFile.getAbsolutePath());

    // Split on white spaces in the line to get words
    TokenizerFactory t = new DefaultTokenizerFactory();
    t.setTokenPreProcessor(new CommonPreprocessor());

    Glove glove = new Glove.Builder()
            .iterate(iter)
            .tokenizerFactory(t)


            .alpha(0.75)
            .learningRate(0.1)

            // number of epochs for training
            .epochs(25)

            // cutoff for weighting function
            .xMax(100)

            // training is done in batches taken from training corpus
            .batchSize(1000)

            // if set to true, batches will be shuffled before training
            .shuffle(true)

            // if set to true word pairs will be built in both directions, LTR and RTL
            .symmetric(true)
            .build();
    log.info("Up here fine");
    glove.fit();  // Getting error here
