Question

我正在使用预训练的FastText模型设置nlp预处理，以查询和保存单词向量。我遇到了FileNotFoundError: [Errno 2] No such file or directory: 'fasttext': 'fasttext'，目前无法解决。

这是针对我正在从事的nlp临床文本相似性项目。我仔细检查以确保目录中存在所有文件和文件夹。我还想指出，我同时使用了floydhub和google colab来确保这不是环境问题。我经历了两次该过程，并最终遇到相同的错误。第二眼肯定会有所帮助。

复制命令fasttext print-vectors model.bin > vectors.vec的代码如下：

with open(VOCAB_FILE) as f_vocab:
    with open(OUTPUT_FILE, 'a') as f_output:
        subprocess.run(
            [FASTTEXT_EXECUTABLE, 'print-word-vectors', PRETRAINED_MODEL_FILE],
            stdin=f_vocab,
            stdout=f_output)

The traceback error I am getting is below:

FileNotFoundError: [Errno 2] No such file or directory: 'fasttext': 'fasttext'

预期结果是能够查询和保存快速文本向量。我们上方的代码段是从github存储库中获得的，并用于Kaggles Quora问题对。

Answer 1

必须安装快速文本才能查询和保存快速文本向量。

复制命令fasttext查询并保存FastText向量
