In the realm of AI, data science, and machine learning, Jupyter Notebooks are highly valued for their interactive capabilities, enabling users to develop with immediate feedback and iterative experimentation.
However, as models grow in complexity and datasets expand, the need for powerful computational resources becomes critical.
Traditional setups often require significant adjustments or sacrifices, such as migrating code to different platforms or dealing with cumbersome configurations to access GPUs.
Additionally, often only a small portion of the code requires GPU acceleration, while the rest can run efficiently on local resources.
What if you could selectively run resource-intensive cells on powerful remote GPUs while keeping the rest of your workflow local?
That's exactly what Datalayer Cell Kernels feature enables. Datalayer works as an extension of the Jupyter ecosystem. With this innovative approach, you can optimize your cost without disrupting your established processes.
We're excited to show you how it works.
The Power of Selective Remote Execution
Datalayer Cell Kernels introduce a game-changing capability: the ability to run specific cells on remote GPUs while keeping the rest of your notebook local. This selective approach offers several advantages:
- Cost Optimization: Only use expensive GPU resources when absolutely necessary.
- Performance Boost: Accelerate computationally intensive tasks without slowing down your entire workflow.
- Flexibility: Seamlessly switch between local and remote execution as needed.
Let's dive into a practical example to see how this works.
We'll demonstrate this hybrid approach using a sentiment analysis task with Google's Gemma-2 model.
Create the LLM Prompt
We start by creating our prompt locally. This part of the notebook runs on your local machine:
prompt = """
Analyze the following customer reviews and provide a structured JSON response for each review. Each response should contain:
- "review_id": A unique identifier for each review.
- "themes": A dictionary where each key is a theme or topic mentioned in the review, and each value is the sentiment associated with that theme (positive, negative, or neutral).
Format your response as a JSON array where each element is a JSON object corresponding to one review. Ensure that the JSON structure is clear and easily parseable.
Customer Reviews:
1. "I love the smartphone's performance and speed, but the battery drains quickly."
2. "The smartphone's camera quality is top-notch, but the battery life could be better."
3. "The display on this smartphone is vibrant and clear, but the battery doesn't last as long as I'd like."
4. "The customer support was helpful when my smartphone had issues with the battery draining quickly. The camera is ok, not good nor bad."
Respond in this format:
[
{
"review_id": "1",
"themes": {
"...": "...",
...
}
},
...
]
"""
Analyse Topics and Sentiment on Remote GPU
Now, here's where we leverage the remote GPU. This cell contains the code to perform sentiment analysis using the Gemma-2 model and the Hugging Face Transformers library.
We'll switch to the Remote Kernel for just this cell:
from huggingface_hub import login
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
login(token="HF_TOKEN")
tokenizer = AutoTokenizer.from_pretrained("google/gemma-2-2b-it")
model = AutoModelForCausalLM.from_pretrained(
"google/gemma-2-2b-it",
device_map="auto",
torch_dtype=torch.bfloat16,
)
chat = [{"role": "user", "content": prompt},]
prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True)
inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt")
outputs = model.generate(input_ids=inputs.to(model.device), max_new_tokens=2000)
prompt_length = inputs.shape[1]
response = tokenizer.decode(outputs[0][prompt_length:])
By executing only this cell remotely, we're optimizing our use of GPU resources. This targeted approach allows us to tap into powerful computing capabilities precisely when we need them, without the overhead of running our entire notebook on a remote machine.
To execute this cell on a remote GPU, you just have to select the remote environment for this cell.
This is done with just a few clicks, as shown below:
With a simple selection from the cell dropdown, you can seamlessly transition from local to remote execution.
Using a Tesla V100S-PCIE-32GB GPU, the sentiment analysis task completes on average in 10 seconds. The number of tokens/seconds processed is ± 19.
The model was pre-downloaded in the remote environment. This was done to eliminate download time. Datalayer lets you customize your computing environment to match your exact needs.
Choose your hardware specifications and install the libraries and models you require.
Datalayer Cell Kernels allow you to manage variable transfers between your local and remote environments.
You can easily configure which variables should be passed from your local setup to the Remote Kernel and vice versa, as illustrated below:
This ensures that your remote computations have access to the data they need and that your local environment can utilize the results of remote processing.
Variable transfers are currently limited in practice to 7 MB of data. This limit is expected to increase in the future, and the option to add data to the remote environment will also be introduced.
To help you monitor and optimize your resource usage, Datalayer provides a clear and intuitive interface for viewing Remote Kernel usage.
Process and Visualize Results Locally
We switch back to local execution for processing and visualizing the results.
This is the processed list of themes and sentiments extracted from the reviews by the Gemma-2 model:
[
{
'review_id': '1',
'themes': {'performance': 'positive', 'speed': 'positive', 'battery': 'negative'}
},
{
'review_id': '2',
'themes': {'camera': 'positive', 'battery': 'negative'}
},
{
'review_id': '3',
themes': {'display': 'positive', 'battery': 'negative'}
},
{
'review_id': '4',
'themes': {'customer support': 'positive', 'camera': 'neutral', 'battery': 'negative'}
}
]
And below is a visualization of the theme and sentiment distribution across the reviews:
Key Takeaways
Datalayer Cell Kernels allow you to selectively run specific cells on remote GPUs.
This hybrid approach optimizes both performance and cost by using remote resources only when necessary.
Complex tasks like sentiment analysis with large language models become more accessible and efficient.
