then press Enter).
Monitor GPU Status#
To monitor your GPU’s performance and status (e.g. memory consumption, utilization, etc.), you can use either the Windows Task Manager (in Performance
Tab) (see the left side of the figure below) or the Arc Control application (see the right side of the figure below)
A Quick Example#
Now let’s play with a real LLM. We’ll be using the Qwen-1.8B-Chat model, a 1.8 billion parameter LLM for this demonstration. Follow the steps below to setup and run the model, and observe how it responds to a prompt “What is AI?”.
Step 1: Follow Runtime Configurations Section above to prepare your runtime environment.
Step 2: Install additional package required for Qwen-1.8B-Chat to conduct:
pip install tiktoken transformers_stream_generator einops
Step 3: Create code file. IPEX-LLM supports loading model from Hugging Face or ModelScope. Please choose according to your requirements.
Create a new file named
demo.py
and insert the code snippet below to run Qwen-1.8B-Chat model with IPEX-LLM optimizations.# Copy/Paste the contents to a new file demo.py import torch from ipex_llm.transformers import AutoModelForCausalLM from transformers import AutoTokenizer, GenerationConfig generation_config = GenerationConfig(use_cache=True) print('Now start loading Tokenizer and optimizing Model...') tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen-1_8B-Chat", trust_remote_code=True) # Load Model using ipex-llm and load it to GPU model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen-1_8B-Chat", load_in_4bit=True, cpu_embedding=True, trust_remote_code=True) model = model.to('xpu') print('Successfully loaded Tokenizer and optimized Model!') # Format the prompt question = "What is AI?" prompt = "user: {prompt}\n\nassistant:".format(prompt=question) # Generate predicted tokens with torch.inference_mode(): input_ids = tokenizer.encode(prompt, return_tensors="pt").to('xpu') print('--------------------------------------Note-----------------------------------------') print('| For the first time that each model runs on Intel iGPU/Intel Arc™ A300-Series or |') print('| Pro A60, it may take several minutes for GPU kernels to compile and initialize. |') print('| Please be patient until it finishes warm-up... |') print('-----------------------------------------------------------------------------------') # To achieve optimal and consistent performance, we recommend a one-time warm-up by running `model.generate(...)` an additional time before starting your actual generation tasks. # If you're developing an application, you can incorporate this warm-up step into start-up or loading routine to enhance the user experience. output = model.generate(input_ids, do_sample=False, max_new_tokens=32, generation_config=generation_config) # warm-up print('Successfully finished warm-up, now start generation...') output = model.generate(input_ids, do_sample=False, max_new_tokens=32, generation_config=generation_config).cpu() output_str = tokenizer.decode(output[0], skip_special_tokens=True) print(output_str)
Please first run following command in Anaconda Prompt to install ModelScope:
pip install modelscope==1.11.0
Create a new file named
demo.py
and insert the code snippet below to run Qwen-1.8B-Chat model with IPEX-LLM optimizations.# Copy/Paste the contents to a new file demo.py import torch from ipex_llm.transformers import AutoModelForCausalLM from transformers import GenerationConfig from modelscope import AutoTokenizer generation_config = GenerationConfig(use_cache=True) print('Now start loading Tokenizer and optimizing Model...') tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen-1_8B-Chat", trust_remote_code=True) # Load Model using ipex-llm and load it to GPU model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen-1_8B-Chat", load_in_4bit=True, cpu_embedding=True, trust_remote_code=True, model_hub='modelscope') model = model.to('xpu') print('Successfully loaded Tokenizer and optimized Model!') # Format the prompt question = "What is AI?" prompt = "user: {prompt}\n\nassistant:".format(prompt=question) # Generate predicted tokens with torch.inference_mode(): input_ids = tokenizer.encode(prompt, return_tensors="pt").to('xpu') print('--------------------------------------Note-----------------------------------------') print('| For the first time that each model runs on Intel iGPU/Intel Arc™ A300-Series or |') print('| Pro A60, it may take several minutes for GPU kernels to compile and initialize. |') print('| Please be patient until it finishes warm-up... |') print('-----------------------------------------------------------------------------------') # To achieve optimal and consistent performance, we recommend a one-time warm-up by running `model.generate(...)` an additional time before starting your actual generation tasks. # If you're developing an application, you can incorporate this warm-up step into start-up or loading routine to enhance the user experience. output = model.generate(input_ids, do_sample=False, max_new_tokens=32, generation_config=generation_config) # warm-up print('Successfully finished warm-up, now start generation...') output = model.generate(input_ids, do_sample=False, max_new_tokens=32, generation_config=generation_config).cpu() output_str = tokenizer.decode(output[0], skip_special_tokens=True) print(output_str)
Tip
Please note that the repo id on ModelScope may be different from Hugging Face for some models.
Note
When running LLMs on Intel iGPUs with limited memory size, we recommend setting
cpu_embedding=True
in thefrom_pretrained
function. This will allow the memory-intensive embedding layer to utilize the CPU instead of GPU.Step 4. Run
demo.py
within the activated Python environment using the following command:python demo.py
Example output#
Example output on a system equipped with an Intel Core Ultra 5 125H CPU and Intel Arc Graphics iGPU:
user: What is AI?
assistant: AI stands for Artificial Intelligence, which refers to the development of computer systems that can perform tasks that typically require human intelligence, such as visual perception, speech recognition,
Tips & Troubleshooting#
Warm-up for optimal performance on first run#
When running LLMs on GPU for the first time, you might notice the performance is lower than expected, with delays up to several minutes before the first token is generated. This delay occurs because the GPU kernels require compilation and initialization, which varies across different GPU types. To achieve optimal and consistent performance, we recommend a one-time warm-up by running model.generate(...)
an additional time before starting your actual generation tasks. If you’re developing an application, you can incorporate this warm-up step into start-up or loading routine to enhance the user experience.
