bartowski/Liberated-Qwen1.5-7B-GGUF-old · Failing to load oobabooga

Hi. Thanks for all the models!
I am using https://github.com/oobabooga/text-generation-webui, main branch commit 91a7370. Latest dependencies pulled from today (although I have tried a few times over the last month), Linux Mint 21.3 Cinnamon. I managed to get bartowski/Liberated-Qwen1.5-7B-exl2 to work but it spits out some weird text sometimes. I have not had much luck with EXL2 generally although its very fast.

I get the following error:

    bos_token = metadata['tokenizer.ggml.tokens'][metadata['tokenizer.ggml.bos_token_id']]
KeyError: 'tokenizer.ggml.bos_token_id'

Any ideas about how this can be made to work?
