Question #: 99
Topic #: 3

[All Professional Machine Learning Engineer Questions]

You are developing an image recognition model using PyTorch based on ResNet50 architecture. Your code is working fine on your local laptop on a small subsample. Your full dataset has 200k labeled images You want to quickly scale your training workload while minimizing cost. You plan to use 4 V100 GPUs. What should you do? (Choose Correct Answer and Give Reference and Explanation)

AConfigure a Compute Engine VM with all the dependencies that launches the training Train your model with Vertex Al using a custom tier that contains the required GPUs.

BPackage your code with Setuptools. and use a pre-built container Train your model with Vertex Al using a custom tier that contains the required GPUs.

CCreate a Vertex Al Workbench user-managed notebooks instance with 4 V100 GPUs, and use it to train your model

DCreate a Google Kubernetes Engine cluster with a node pool that has 4 V100 GPUs Prepare and submit a TFJob operator to this node pool.

Show Suggested Answer

Suggested Answer: C

Traffic splitting is a feature of Vertex AI that allows you to distribute the prediction requests among multiple models or model versions within the same endpoint. You can specify the percentage of traffic that each model or model version receives, and change it at any time. Traffic splitting can help you test the new model in production without creating a new endpoint or a separate service. You can deploy the new model to the existing Vertex AI endpoint, and use traffic splitting to send 5% of production traffic to the new model. You can monitor the end-user metrics, such as listening time, to compare the performance of the new model and the previous model. If the end-user metrics improve between models over time, you can gradually increase the percentage of production traffic sent to the new model. This solution can help you test the new model in production while minimizing complexity and cost.Reference:

Wait, I can use my refrigerator as a GPU? *scratches head* Nah, that's probably not a good idea. Time to get serious and go with Option B. Gotta package that code up and let Vertex AI handle the heavy lifting!

Hmm, I'm not sure I trust any of these options. I think I'll just train my model on my local laptop and hope it scales eventually. Who needs fancy cloud infrastructure anyway? *laughs nervously*

Using cloud infrastructure like Vertex AI can greatly speed up your training process and save you time in the long run. It's worth considering!

Option A seems like the best choice for scaling your training workload with minimal cost. You should configure a Compute Engine VM with the necessary dependencies and use Vertex AI with custom tier containing the required GPUs.

Option D is intriguing, but it sounds a bit more complex than I'd like to deal with. Setting up a GKE cluster and submitting a TFJob operator seems like a lot of work. I'm more interested in a simpler, managed solution like Vertex AI.

I'm leaning towards Option C. Creating a Vertex AI Workbench instance with the required GPUs sounds like a great way to get my model training up and running quickly. Plus, I don't have to worry about managing the infrastructure myself.
