# MODEL_ID = "eu.meta.llama3-2-90b-instruct-v1:0"
IMAGE_NAME = "share-electricity-renewable-small.png"
bedrock_runtime = boto3.shopper("bedrock-runtime")
with open(IMAGE_NAME, "rb") as f:
picture = f.learn()
user_message = "Based mostly on this chart, which international locations in Europe have the very best share?"
messages = [
{
"role": "user",
"content": [
{"image": {"format": "png", "source": {"bytes": image}}},
{"text": user_message},
],
}
]
response = bedrock_runtime.converse(
modelId=MODEL_ID,
messages=messages,
)
