The textual content strings to transform to embeddings.
texts = [
"Star Wars: A farm boy joins rebels to fight an evil empire in space",
"Jurassic Park: Scientists create dinosaurs in a theme park that goes wrong",
"Finding Nemo: A father fish searches the ocean to find his lost son"]
embeddings=[]
#Generate vector embeddings for the enter texts
for textual content in texts:
physique = json.dumps({
"inputText": textual content
})
# Name Bedrock's embedding API
response = bedrock.invoke_model(
modelId='amazon.titan-embed-text-v2:0', # Titan embedding mannequin
physique=physique)
# Parse response
response_body = json.hundreds(response['body'].learn())
embedding = response_body['embedding']
embeddings.append(embedding)Now, you’ll be able to insert vector embeddings into the vector index and question vectors in your vector index utilizing the question embedding:
# Create S3Vectors consumer
s3vectors = boto3.consumer('s3vectors', region_name="us-west-2")
# Insert vector embedding
s3vectors.put_vectors( vectorBucketName="channy-vector-bucket",
indexName="channy-vector-index",
vectors=[
{"key": "v1", "data": {"float32": embeddings[0]}, "metadata": {"id": "key1", "source_text": texts[0], "style":"scifi"}},
{"key": "v2", "knowledge": {"float32": embeddings[1]}, "metadata": {"id": "key2", "source_text": texts[1], "style":"scifi"}},
{"key": "v3", "knowledge": {"float32": embeddings[2]}, "metadata": {"id": "key3", "source_text": texts[2], "style":"household"}}
],
)
#Create an embedding in your question enter textual content
# The textual content to transform to an embedding.
input_text = "Listing the flicks about adventures in area"
# Create the JSON request for the mannequin.
request = json.dumps({"inputText": input_text})
# Invoke the mannequin with the request and the mannequin ID, e.g., Titan Textual content Embeddings V2.
response = bedrock.invoke_model(modelId="amazon.titan-embed-text-v2:0", physique=request)
# Decode the mannequin's native response physique.
model_response = json.hundreds(response["body"].learn())
# Extract and print the generated embedding and the enter textual content token rely.
embedding = model_response["embedding"]
# Performa a similarity question. You may as well optionally use a filter in your question
question = s3vectors.query_vectors( vectorBucketName="channy-vector-bucket",
indexName="channy-vector-index",
queryVector={"float32":embedding},
topK=3,
filter={"style":"scifi"},
returnDistance=True,
