I tried the above approach from past few days. The processor function is not optimised to handle batch images, texts and the output it generates for two examples is also very high in memory.

@samyak24jain did you fix the error??

Could this be fixed by #16 by @sebbyjp ?

@WilliamSotoM It guess it should

try out https://wandb.ai/byyoung3/mlnews3/reports/How-to-fine-tune-Phi-3-Vision-on-a-custom-dataset--Vmlldzo4MTEzMTg3

Thanks @bdytx5 ! This is helpful.

I used the code from Wanda.ai blog on dataset preparation and combined it with peft lora but I am getting below error when training using trainer fucntion
Have added link to download the dataset file(mars_dataset.csv) and original dataset is available on hugging face :-

can someone help? > i have the same error

@bdytx5 @samyak24jain @WilliamSotoM @digitalesingulary @Magneto

You could use this code for fine-tuning the model!

https://github.com/2U1/Phi3-Vision-ft

You could use this code. It also has the options to tune img_projector and vision_model together like llava-1.6.

Got stuck with the same "The processor function is not optimised to handle batch images, texts ", so have to prepare the dataset in dataloader format.
@Magneto Thanks a lot for the code, was really helpful,

But while trying to recreate your code results, got error

    49                 data = self.dataset.__getitems__(possibly_batched_index)
     50             else:

     52         else:
     53             data = self.dataset[possibly_batched_index]

TypeError: 'DataLoader' object is not subscriptable

i`ve installed all latest version

!pip install -q git+https://github.com/huggingface/transformers.git
!pip install -q accelerate datasets peft bitsandbytes flash_attn

Can someone please help me out why trainer function doesn't accept Data Loader as train dataset..

is this due to the version issues ?

@EphronM As you can see here, the Trainer class in huggingface takes dataset as input. I think you should change to dataset again.
