Convert bloomz-7b1-mt to ggml error.

[ghost]

I have the following problems when converting bloomz-7b1-mt model:

Some weights of BloomForCausalLM were not initialized from the model checkpoint at D:\projects\code\bloomz-7b1-mt and are newly initialized: ['lm_head.weight']
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.
