## Code

```python theme={null}
from agno.knowledge.embedder.huggingface import HuggingfaceCustomEmbedder
from agno.knowledge.knowledge import Knowledge
from agno.vectordb.pgvector import PgVector

embeddings = HuggingfaceCustomEmbedder().get_embedding(
    "The quick brown fox jumps over the lazy dog."
)

# Print the embeddings and their dimensions
print(f"Embeddings: {embeddings[:5]}")
print(f"Dimensions: {len(embeddings)}")

# Example usage:
knowledge = Knowledge(
    vector_db=PgVector(
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai",
        table_name="huggingface_embeddings",
        embedder=HuggingfaceCustomEmbedder(dimensions=1024),
