Thus, these tools democratize access. In the following sections, follow step-by-step guides for popular methods.
Step-by-Step Guide: Running Gemma 3 270M with Hugging Face Transformers
You start by installing the necessary libraries. Open your terminal and execute:
pip install transformers torch
This command fetches Transformers and PyTorch. Next, import the components in a Python script:
from transformers import AutoTokenizer, AutoModelForCausalLM
Load the model and tokenizer:
model_name = "google/gemma-3-270m"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto")
The device_map="auto" places the model on GPU if available. Prepare your input:
input_text = "Explain quantum computing in simple terms."
inputs = tokenizer(input_text, return_tensors="pt").to(model.device)
Generate output:
outputs = model.generate(**inputs, max_new_tokens=200)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
This produces a coherent explanation. To optimize, add quantization:
from transformers import BitsAndBytesConfig
quant_config = BitsAndBytesConfig(load_in_4bit=True)
model = AutoModelForCausalLM.from_pretrained(model_name, quantization_config=quant_config)
Quantization reduces memory usage. You handle errors by ensuring Hugging Face login for gated models:
from huggingface_hub import login
login(token="your_hf_token")
Obtain the token from your Hugging Face account. With this setup, you run inferences repeatedly. However, for non-Python users, consider LM Studio next.

from peft import LoraConfig, get_peft_model
lora_config = LoraConfig(r=16, lora_alpha=32, target_modules=["q_proj", "v_proj"])
model = get_peft_model(model, lora_config)
Prepare a dataset, then train:
from transformers import Trainer, TrainingArguments
trainer = Trainer(model=model, args=TrainingArguments(output_dir="./results"))
trainer.train()
LoRA requires little data, finishing quickly on modest hardware. Save and reload the adapter. This boosts performance on custom tasks like chess move prediction. However, monitor overfitting.
