I tried to implement https://huggingface.co/blog/fine-tune-vit

Training runs fine. Inference though produces something weird. I need the logits of the model (array of three classes-scores). But I get something different. Does it even load my trained model? Do I get the last layer (output for three classes) or is this the feature-vector one layer below?

IMPORTANT:
I want to run this in a docker. So first step for you is to build the docker in order to replicate what I did.

Please find all files in https://gitlab.com/boprinnit/tarkapp

STEPS:
- Make a docker with Dockerfile_kivy
- Tag it tarkov_docker:latest
- Start a docker session with
xhost + \
&& xhost +local:docker \
&& docker run --net=host -e DISPLAY=unix$DISPLAY --privileged -v ~/dev/git:/root/dev/git -v ~/dev/pv_data:/root/dev/pv_data -v /var/www/vhosts:/var/www/vhosts -it tarkov_docker:latest /bin/bash
- train a model by
- cd ~/dev/git/tarkov/hugging_image_classifier_vit
- python3 train.py

BUT THEN when I run python3 inference.py I get some weird messages and a vector of not 3 but hundreds of floats. I would expect three (one for each class). Here are the details:

Some weights of the model checkpoint at vit-base-beans-demo-v5/checkpoint-60 were not used when initializing ViTModel: ['classifier.bias', 'classifier.weight']
- This IS expected if you are initializing ViTModel from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
- This IS NOT expected if you are initializing ViTModel from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).
Some weights of ViTModel were not initialized from the model checkpoint at vit-base-beans-demo-v5/checkpoint-60 and are newly initialized: ['vit.pooler.dense.bias', 'vit.pooler.dense.weight']
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

TO CONCLUDE:
Your job is to fix the given files so that the inference runs and gives the classification result between the three (!!!) trained classes of the trained model.

IMPORTANT: Must be fixed in the next 48 hours
