Hi, could you please provide more information about your case (e.g. the device_map for loading and the number of GPUs you are using). Also, can you try to load the 8/13b model to see whether the same problem happens?

[CSEEduanyu]

transformers in my env is 4.39 , why must transformers==4.37.0 in dependencies ?

[CSEEduanyu]

all dependencies is "== " ， I wonder if ">" is OK？

[penghao-wu]

Our training and evaluation are mainly conducted with the specified versions and haven't been extensively tested with higher versions to ensure correctness. But I have tested to run the 34B model with transformers==4.39.0 and it works fine. Could you provide the information about device_map for loading and the number of GPUs you are using? Also, what is the version of your accelerate?

when i add some log , is loding "model.mm_projector_aux_0.0.weight" @penghao-wu

[CSEEduanyu]

Is it because I only kept the second one in mm_vision_tower_aux_list?

[penghao-wu]

What do you mean by this? You don't need to modify the config if you want to load our trained model.

because i can only load local path model，Can you list the huggingface download addresses for these four vision models?

"mm_vision_tower_aux_list": [ "siglip/CLIP-ViT-SO400M-14-384", "openai/clip-vit-large-patch14-336", "facebook/dinov2-giant-res378", "clip-convnext-XXL-multi-stage" ],

[CSEEduanyu]

For example, CLIP-ViT-SO400M-14-384 seems to have many versions, and I can't search clip-conv-xxL-multi-stage in huggfing face

[penghao-wu]

CLIP-ViT-SO400M-14-384 should be hf-hub:timm/ViT-SO400M-14-SigLIP-384 and clip-conv-xxL-multi-stage should be hf-hub:laion/CLIP-convnext_xxlarge-laion2B-s34B-b82K-augreg-soup . If you use local path, you might need to look into the loading code for each of the vision encoders in the cambrian/model/multimodal_encoder folder to ensure the correctness.

Hi, how can I set 2 48G gpus?

[penghao-wu]

return _sentencepiece.SentencePieceProcessor_LoadFromFile(self, arg) TypeError: not a string

This error seems not related to multiple GPUs. Make sure that all model files are downloaded correctly (e.g. tokenizer.model)

[penghao-wu]

@dionren Some of the vision encoders are not from transformers and do not support device_map, so there are some problems setting device_map=auto using multiple GPUs. And we are still working to convert the vision encoders to support this.

But I have a workaround for your case with 2 48G gpus. This includes the following modifications:

1. Modify the beginning of cambrian/model/builder.py

   
   from accelerate import infer_auto_device_map, dispatch_model

def load_pretrained_model(model_path, model_base, model_name, load_8bit=False, load_4bit=False, device_map="auto", device="cuda", kwargs): device_map='sequential' kwargs = {"device_map": device_map, "max_memory":{0: "30GIB", 1: "49GIB"}, kwargs}

2. Change https://github.com/cambrian-mllm/cambrian/blob/9d382223ba3e0ab9f99bad4f45c0fd4a21749dc6/cambrian/model/language_model/cambrian_llama.py#L252 to
```cur_latent_query_with_newline = torch.cat([cur_latent_query, cur_newline_embd.to(cur_latent_query.device)], 2).flatten(1,2)```

I'm gonna try it out. Thanks a ton for your help and the awesome work you've done. It's truly impressive.
