Hi - please check our repo (https://github.com/microsoft/LLaVA-Med?tab=readme-ov-file#contents) for the use of LLaVA-Med v1.5.

Hi, thanks for you response. I want to finetune your base-model on my own data. Let me know if it is possible to do so in near future? Thank you

Hi, did you solve the problem? I met the same problem that Transformers does not recognize this architecture. I download the model files and run them offline.

No. It's not possible. We switched to original llava model.

Hello. I want to fine tune the Llava-med on my own dataset. Is it possible, did you find a solution?

I can load it successfully, steps are as following:

1. clone repository from https://github.com/microsoft/LLaVA-Med and create virtual environment
2. download parameters from this repository
3. use the following code to load model:

from llava.model.builder import load_pretrained_model
tokenizer, model, image_processor, context_len = load_pretrained_model(
        model_path='<path_to_downloaded_repository(this)>',
        model_base=None,
        model_name='llava-med-v1.5-mistral-7b'
 )

Then I can use this model like any other models in Hugging Face transformers library.

Thanks for the update @mizukiQ

Also, wanted to ask - what's the max resolution of image that can be used? ViTL14 supports 224 x 224.
And what are various strategies to handle CT/ MR images.

I am also willing to join on discord or zoom to catchup and exchange-notes with other builders in the space.

Best,
Shash

thank you!
I also want to ask how should I prepare my dataset. I have images and captions. How should I convert them for fine tuning on lava med?
Is there any tutorial ?

I am not the official researcher of llava-med, here's some configuration from their code:
llava-med utilizes CLIPImageProcessor to handle image, and its crop_size is (336, 336), and it will split it into patches with shape (24, 24), where each patch is 14 x 14.
llava-med handles the images in different modalities (CT or MR) in the same way.

thank you!

I publish some data loading code here (the code is from my reproduction of llava-med, it may be not good enough)
You can replace SlakeDataset class with your own dataset class (since image caption and vqa have the similar form I + Q -> T), just keep two interfaces the same. and finetune the model.

I actually want to convert my image-text pair dataset to QA dataset like in the paper.
So I need to get question and answers from my texts first.
maybe after that I can use the exact code without changing in the repo
do you have any recommendation for that "meta-llama/Llama-3-8b-chat-hf" and "meta-llama/Meta-Llama-3-8B-Instruct" models seems suitable for this task

hey, awesome solution
i have a bug that my path does not appear to have a file named config.json
any help?
thanks

i have a bug that my path does not appear to have a file named config.json
any help? did you solve this error?

can anyone send the updated code.. now i am not able to load the model

@marinasam @satheeshkola532

I am confused about your problem. This repository (https://huggingface.co/microsoft/llava-med-v1.5-mistral-7b) does contain config.json.
How about re-cloning this repository and checking file integrity?

Easiest way to load

git clone https://github.com/microsoft/LLaVA-Med

Then in this directory run this

from llava.model.builder import load_pretrained_model
model_path='microsoft/llava-med-v1.5-mistral-7b'
model_base=None
model_name='llava-med-v1.5-mistral-7b'
tokenizer, model, image_processor, context_len = load_pretrained_model(model_path, model_base, model_name, load_8bit=False, load_4bit=False, device="cuda")

For quantized loading though, this doesn't work with some strange errors like llava_mistral is unrecognized
This can be bypassed by

from transformers import AutoTokenizer, BitsAndBytesConfig
from llava.model import LlavaMistralForCausalLM
from transformers import AutoModelForCausalLM

model_path = "microsoft/llava-med-v1.5-mistral-7b"
kwargs = {"device_map": "auto"}
kwargs['load_in_4bit'] = True
kwargs['quantization_config'] = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_compute_dtype=torch.float16,
    bnb_4bit_use_double_quant=True,
    bnb_4bit_quant_type='nf4'
)
#model = AutoModelForCausalLM.from_pretrained(model_path, low_cpu_mem_usage=True, **kwargs)
model = LlavaMistralForCausalLM.from_pretrained(model_path, low_cpu_mem_usage=True, **kwargs)
tokenizer = AutoTokenizer.from_pretrained(model_path, use_fast=False)

*AutoModelForCausalLM did work for me sometimes. But I can't seem to reproduce it now

Whenever I try to follow the previously mentioned instructions, I always get "Some weights of the model checkpoint at llava-med-v1.5-mistral-7b were not used when initializing LlavaMistralForCausalLM: ['model.vision_tower.vision_tower.vision_model.encoder.layers.1.self_attn.v_proj.weight'...". My understanding is that the pretrained vision_tower from llava-med-v1.5-mistral-7b is not being used and, instead, another pretrained vision tower from the LLava-med repository is being used. Can anyone clarify?

Before loading the model, could someone please explain to me how to download parameters from the repository ? I dont understand this step

It is more easier to follow this .py file: LLaVA-Med/llava/eval/model_vqa.py

It would be cool is someone converted the weights to the Transformers-native model, LlavaForConditionalGeneration.

Here's the conversion script: https://github.com/huggingface/transformers/blob/main/src/transformers/models/llava/convert_llava_weights_to_hf.py.

I can load it successfully, steps are as following:

1. clone repository from https://github.com/microsoft/LLaVA-Med and create virtual environment
2. download parameters from this repository
3. use the following code to load model:

from llava.model.builder import load_pretrained_model
tokenizer, model, image_processor, context_len = load_pretrained_model(
        model_path='<path_to_downloaded_repository(this)>',
        model_base=None,
        model_name='llava-med-v1.5-mistral-7b'
 )

Then I can use this model like any other models in Hugging Face transformers library.

hi，could you give me a sample code that can directly use pictures and questions to generate answers? My code keeps reporting errors and cannot be generated.
