Live Example

Here is a functional code block demonstrating the use of vLLM:

import torch
from vllm import Worker, GPU

# Initialize the worker and GPU
worker = Worker()
gpu = GPU()

# Load the pre-trained model
model = torch.load("model.pth")

# Set the input and output tensors
input_tensor = torch.randn(1, 3, 224, 224)
output_tensor = torch.randn(1, 3, 224, 224)

# Perform inference on the GPU
output = worker.inference(gpu, model, input_tensor)

# Print the output
print(output)

This code block demonstrates how to use the vLLM library to perform inference on a pre-trained model using the GPU. It initializes the worker and GPU, loads the pre-trained model, sets the input and output tensors, and performs inference on the GPU.
