Error with translate-en_zh-1_9.argosmodel

[xinliu9451]

terminate called after throwing an instance of 'std::runtime_error'
what(): Unsupported model binary version. This executable supports models with binary version v5 or below, but the model has binary version v6. This usually means that the model was generated by a later version of CTranslate2. (Forward compatibility is not guaranteed.)

Is there a solution to this problem?

You need a newer version of Argos Translate and CTranslate2. CTranslate2 models aren't forward compatible

My CTranslate2 has been upgraded to v2.24.0, but it still reports errors. If I continue to upgrade to the latest version, it reports an error saying that the include/ctranslate2/translator_pool.h file is missing. What are some other solutions to this problem?

I also encountered the same problem

I upgraded CTranslate2 to v4.4.0, and the CHANGELOG.md said the change are "* Rename or remove some classes and methods:

• TranslationStats -> ExecutionStats
• GeneratorPool -> Generator
• TranslatorPool -> Translator
• TranslatorPool::consume_* -> Translator::translate_*
• TranslatorPool::consume_stream -> removed
• TranslatorPool::score_stream -> removed"

I think the en_zh 1.9 model was ported from Opus-MT using LibreTranslate/Locomotive and ctranslate2==3.20.0. I think we need a version of CTranslate2 newer than that for it to work.

I think the best solution is to update the CTranslate2 git submodule in third_party but I'm open to suggestions.

Also are you guys using the Argos Translate models in MetalTranslate? That's awesome. If you have notes/docs feel free to make a pull request and I can merge them. Or fork the repo and I can link to the fork from the README.
