Set Up Your Google Cloud Platform Environment
- Create a Google Cloud Project. Navigate to the [Google Cloud Console](https://console.cloud.google.com/), click on the project dropdown and select "New Project". Give your project a meaningful name.
- Enable Billing. Google Cloud requires an active billing account setup, so make sure to enable billing for your new project.
- Enable Compute Engine and AI Platform APIs by navigating to the “APIs & Services” section in the console and enabling these APIs.
Configure Your Local Environment
Create a VM Instance with GPU Support
- In the Google Cloud Console, navigate to "Compute Engine > VM Instances", and click "Create Instance".
- Choose a machine type that fits your workload. For PyTorch, it's beneficial to select a machine type with a GPU. Under the “Machine type” section, choose “N1” and select one with GPU support, like n1-standard-4 with a compatible GPU from “GPUs > Add GPU”.
- Configure the disk size and other necessary parameters based on your needs and then click "Create".
- Ensure you have installed the necessary NVIDIA drivers and CUDA Toolkit on your VM as per [NVIDIA’s documentation](https://cloud.google.com/compute/docs/gpus/install-drivers-gpu).
Deploy PyTorch Models on AI Platform
- Prepare your PyTorch model for deployment by saving it in a format that Cloud AI Platform supports, such as TorchScript. Convert your model, you can use:
import torch
import torchvision
# Example model, for illustration.
model = torchvision.models.resnet18(pretrained=True)
scripted_model = torch.jit.script(model)
scripted_model.save('model.pt')
- Upload your model to Google Cloud Storage (GCS), which can be done with the CLI as follows:
gsutil mb gs://your-bucket-name
gsutil cp model.pt gs://your-bucket-name/
- Deploy the model to AI Platform by running this command:
gcloud ai-platform models create pytorch_model --regions=us-central1
- Create a model version:
gcloud ai-platform versions create v1 --model pytorch_model --framework pytorch --python-version 3.7 --runtime-version 2.2 --origin gs://your-bucket-name/model.pt
Handle Inference Requests
Monitor and Manage Your Deployment
- Utilize Google Cloud’s monitoring tools to keep track of your model’s performance. This can be done using “Stackdriver Monitoring”.
- Regularly check your deployment’s logs for any anomalies or necessary scaling opportunities.
Optimize and Scale as Needed
- Assess your model’s performance and start optimizing your code or scaling your resources accordingly.
- Use managed services like Google Kubernetes Engine (GKE) to automate scaling for significant model request loads.
