When trying to serve the model using tgi:

sudo docker run \
        ghcr.io/huggingface/text-generation-inference:1.3.1 \
        --model-id Open-Orca/Mistral-7B-SlimOrca

It throws:

Okay, got that solved by dropping all except the chat ml tokens from added_tokens.json

Now running into:

Exception: No such file or directory (os error 2)

Which looks like it can be solved by also patching tokenizer_config.json seeing https://github.com/huggingface/transformers/pull/15319
gqd

Okay, can confirm that removing toikenizer_file from tokenizer_config.json fixes it
