Not using GPU although it is specified

Hello, I am new to the huggingface library and I am currently going over the course.

I want to finetune a BERT model on a dataset (just like it is demonstrated in the course), but when I run it, it gives me +20 hours of runtime.

I therefore tried to run the code with my GPU by importing torch, but the time does not go down.

However, in the course, it says it should only take a couple of minutes with a GPU.

Can someone explain what I am doing wrong? I have a NVIDEA RTX 2060, 16GB of DDR4 RAM and an AMD RYZEN 7.

from datasets import load_dataset
from transformers import AutoTokenizer, DataCollatorWithPadding

raw_datasets = load_dataset("glue", "mrpc")
checkpoint = "bert-base-uncased"
tokenizer = AutoTokenizer.from_pretrained(checkpoint)

def tokenize_function(example):
    return tokenizer(example["sentence1"], example["sentence2"], truncation=True)

tokenized_datasets =, batched=True)
data_collator = DataCollatorWithPadding(tokenizer=tokenizer)

from transformers import TrainingArguments

training_args = TrainingArguments("test-trainer")

from transformers import AutoModelForSequenceClassification

model = AutoModelForSequenceClassification.from_pretrained(checkpoint, num_labels=2)

import torch

device = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")
model =
device                                                        #This outputs 'cuda'

from transformers import Trainer

trainer = Trainer(


The code comes almost directly from this link: Fine-tuning a pretrained model - Hugging Face Course

When running, I have a really small peak in my GPU in my task manager at the beginning, but then the load of the GPU returns to 0.

Thank you in advance!

Hey @blommeolivier, can you try running the commands in this Stack Overflow answer?

One line that looks a bit odd in your code is:

model =

This is probably not the source of the problem (since returns self), but is not the conventional way of placing the model on the device. The Trainer does the device placement automatically for you, so you could either remove that line or try:
