OpenNMT-py翻译命令执行报错求助：文件未找到问题

问题背景 #

在OpenNMT-py目录下的sample1文件夹中，已完成两项前置操作：

• 数据准备（创建词汇表）
• 数据训练
  执行翻译命令时触发错误。

执行的命令 #

onmt_translate -model sample1/newmodel_step_1200.pt -src sample1/src-test.hi -output sample1/pred_1000.txt -verbose

报错信息 #

FileNotFoundError: [Errno 2] No such file or directory: 'sample1/src-test.hi'

问题根源 #

报错核心是FileNotFoundError: [Errno 2] No such file or directory: 'sample1/src-test.hi'，说明系统找不到指定路径下的测试源文件src-test.hi。

解决步骤 #

1. 检查文件存在性：打开sample1文件夹，确认是否存在src-test.hi文件，注意文件名大小写、后缀名是否完全匹配。
2. 核对路径正确性：如果当前工作目录不是OpenNMT-py根目录，需改用绝对路径指定文件，例如C:\Users\anurag\OpenNMT-py\sample1\src-test.hi。
3. 补全缺失文件：若文件确实缺失，重新准备测试集数据，将src-test.hi放入sample1文件夹后再执行命令。
