Step-by-Step Installation Guides

Method 1: Hugging Face Transformers (Python)

Step 1: Install Dependencies

pip install transformers torch

Step 2: Set Up Your Python Script

from transformers import AutoTokenizer, AutoModelForCausalLM

# Load model and tokenizer
model_name = "google/gemma-3-270m"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto")

# Prepare input
input_text = "Explain quantum computing in simple terms."
inputs = tokenizer(input_text, return_tensors="pt").to(model.device)

# Generate response
outputs = model.generate(**inputs, max_new_tokens=200)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Step 3: Optimize with Quantization

from transformers import BitsAndBytesConfig

quant_config = BitsAndBytesConfig(load_in_4bit=True)
model = AutoModelForCausalLM.from_pretrained(
    model_name, 
    quantization_config=quant_config
)

Method 2: LM Studio (GUI Approach)

Step 1: Download LM Studio from lmstudio.ai

Step 2: Launch the application and search for "gemma-3-270m" in the model hub

Step 3: Select a quantized variant (Q4_0 recommended) and download

Step 4: Load the model from the sidebar and configure settings:

• Context length: 32,000

• Temperature: 1.0
