T-MAC reports an error when using the 3-bit model

[xdd130]

I try used the AutoGPTQ tool to quantize the Qwen2.5-3B-Instruct model to 3 bits. I successfully obtained the model in GPTQ format, but when I compiled the script using T-MAC：

python compile.py -fa -o tuned -da -nt 8 -tb -gc -gs 128 -ags 64 -m gptq-auto -md /home/phytium/yq/Qwen2.5-3B-yq/Qwen2.5-3B-Quant-3b -t

I got the following error:

Traceback (most recent call last):

tvm._ffi.base.TVMError: K(10304) must be devisible by group_size(128)

Does this indicate that there is a problem with my quantization step or that t-mac does not support the direct use of 3-bit models? What additional operations do I need to do?

@xdd130 Does your model have any weight of shape 10304? Since 10304=64*161, you should set -gs=64 in the command.
