Endless loop

#1
by redaihf - opened

This model goes into a loop after about 1000 tokens that continues until the context exhausts. Looping happens for both safe and unsafe content with a temperature of 0.75 and a repeat penalty of 1.08. The repeated content is usually a few short paragraphs of text.

This could be something caused by dare_linear or maybe some components are bugged I'll have to look into it further.

Did you try with lower temps and rep pen 1.12?

I suspect this might be caused by mixing llama with nemotron models. In my recent model_stock tests, it reported too much cosine dissimilarity, much like with the 2501 and 2509 Mistral 24B models.

I'm working on a Nemotron-only merge now with (mostly) my finetunes, and noticed some early terminations there as well when using the della method. It might have something to do with Assistant Pepe using "content": "<|end_of_text|>",instead of "content": "<|eot_id|>", in the special_tokens_map.json.

I'm comparing a version with and without Pepe to inspect this further. Also comparing karcher to della, SCE and model_stock

Update

Surprisingly, the version without Pepe had more early terminations than the one with Pepe. So it must be something else

I think the problem might be related to tokenizer_source: union because when i switched to morpheus tokenizer and swapped pepe's special token map json the early terminations went away (at least from initial tests)
