AWS CDK utility

The primary AWS CDK utility is contained within the file within the root listing. The venture consists of a number of stacks, so now we have to import the stacks:

#!/usr/bin/env python3
import aws_cdk as cdk

from stack.generative_ai_vpc_network_stack import GenerativeAiVpcNetworkStack
from stack.generative_ai_demo_web_stack import GenerativeAiDemoWebStack
from stack.generative_ai_txt2nlu_sagemaker_stack import GenerativeAiTxt2nluSagemakerStack
from stack.generative_ai_txt2img_sagemaker_stack import GenerativeAiTxt2imgSagemakerStack

We outline our generative AI fashions and get the associated URIs from SageMaker:

from script.sagemaker_uri import *
import boto3

region_name = boto3.Session().region_name
env={"area": region_name}

#Textual content to Picture mannequin parameters
TXT2IMG_MODEL_ID = "model-txt2img-stabilityai-stable-diffusion-v2-1-base"
TXT2IMG_MODEL_INFO = get_sagemaker_uris(model_id=TXT2IMG_MODEL_ID,

#Textual content to NLU picture mannequin parameters
