If you want to upgrade pymilvus to newest version

$ pip install --upgrade pymilvus

Import

from milvus import Milvus, IndexType, Status

Getting started

Initial a Milvus instance and connect to the sever

>>> milvus = Milvus()

>>> milvus.connect(host='SERVER-HOST', port='SERVER-PORT')
Status(code=0, message="Success")

Once successfully connected, you can get the version of server

>>> milvus.server_version()
(Status(code=0, message='Success'), 0.3.1)  # this is example version, the real version may vary

Add a new table

First set param

>>> param = {'table_name':'test01', 'dimension':256, 'index_type':IndexType.FLAT, 'store_raw_vector':False}

Then create table

>>> milvus.create_table(param)
Status(message='Table test01 created!', code=0)

Describe the table we just created

>>> milvus.describe_table('test01')
(Status(code=0, message='Success!'), TableSchema(table_name='test01',dimension=256, index_type=<IndexType: FLAT>, store_raw_vector=False))

Add vectors into table test01

First create 20 vectors of 256-dimension.

  • Note that random and pprint we used here is for creating fake vectors data and pretty print, you may not need them in your project
>>> import random
>>> from pprint import pprint

>>> dim = 256  # Dimension of the vector

# Initialize 20 vectors of 256-dimension
>>> fake_vectors = [[random.random() for _ in range(dim)] for _ in range(20)]

Then add vectors into table test01

>>> status, ids = milvus.add_vectors(table_name='test01', records=vectors)
>>> print(status)
Status(code=0, message='Success')
>>> pprint(ids) # List of ids returned
23455321135511233
12245748929023489
...

Search vectors

# create 5 vectors of 256-dimension
>>> q_records = [[random.random() for _ in range(dim)] for _ in range(5)]

Then get results

>>> status, results = milvus.search_vectors(table_name='test01', query_records=q_records, top_k=10)
>>> print(status)
Status(code=0, message='Success')
>>> pprint(results) # Searched top_k vectors

Delet the table we just created

>>> milvus.delete_table(table_name='test01')
Status(code=0, message='Success')

Disconnect with the server

>>> milvus.disconnect()
Status(code=0, message='Success')
