Getting syntax error when running

See error here: File "privateGPT.py", line 26 match model_type: ^ SyntaxError: invalid syntax

Code is below:

import os

load_dotenv()

llama_embeddings_model = os.environ.get("LLAMA_EMBEDDINGS_MODEL") persist_directory = os.environ.get('PERSIST_DIRECTORY')

model_type = os.environ.get('MODEL_TYPE') model_path = os.environ.get('MODEL_PATH') model_n_ctx = os.environ.get('MODEL_N_CTX')

from constants import CHROMA_SETTINGS
