failed to cast tokenizer

[frederickmannings]

Strange behaviour when trying to run a huggingface embedding pipeline within a test, resulting in error:

The same process works just fine when running outside of tests. @daulet any ideas about what might be the issue here? tokenizers.a is present in /usr/lib/

Using Hugot as the library to generate embeddings.

It's finding the file just fine. Seems to have an issue with parsing it.

[daulet]

@frederickmannings can you share the config? perhaps minimized version if you can reduce it to essential repro?

[frederickmannings]

Thanks @daulet for replying. I will try and shrink this down to the minimal example.
