Adding Support for Custom Qwen2moe Architectures with mergekit-qwen2 #6453
base: master
Are you sure you want to change the base?
Conversation
Thanks @DisOOM for creating this PR based on our discussion regarding why MoE models based on Qwen don't work properly. I will tag @compilade and @slaren who was involve in the PR you mentioned. However, have you tried using this PR to see if the MoE models based on Qwen architecture works properly? #6387 I am testing #6387 now for DBRX, but if it's to solve issues with MoE (not sure if there is a difference between Mergekit MoE and others like Qwen, Mixtral, DBRX). I would personally try it to see if my quantized Qwen MoE model would work. |
I haven't tried this PR yet. I will give it a try later. |
I have pulled and used the latest changes from the It works very fine and has a coherent output. However, any quantized model from this pf16 results in the following error:
@ggerganov I am not sure what causes this error. This is a MoE made by MergeKit based on Qwen models. (one of those situation where the fp16 GGUF model works fine, but the quantized just either crashes or outputs nonsense) |
Statement: This has nothing to do with the fine-grained MoE architecture in Qwen/Qwen1.5-MoE-A2.7B. It is more akin to a traditional MoE, except that its experts are derived from the qwen2 (qwen1.5) model.
I was previously using mergekit-moe to merge the qwen1.5 model into an MoE, but the resulting models were corrupted after being converted into the gguf format.
Subsequently, I discovered this custom mergekit script that successfully merges into qwen2MoE: https://github.com/Aratako/mergekit-qwen2. Following the example of #4912, I made some modifications to llama.cpp, enabling it to correctly convert, quantize, and run MoEs merged using this custom script.
It performs well on older versions, but I encountered errors with the latest version. It can correctly convert and quantize but fails to run. I believe the issue lies in incompatibility with the changes made to llamacpp in #6122, but I am unsure how to resolve this problem.
I am a newbie to coding and this is my first PR, please be lenient.
I encountered no issues when converting with convert-hf-to-gguf.py and quantizing with quantize.exe, but I encountered the following issues when I ran main.exe.
