[Bug]: Create collection will fail using number for int8 field instead of numpy.int8

[NicoYuan1986]

Is there an existing issue for this?

• [X] I have searched the existing issues

Environment

- Milvus version: master-20230530-b09e7aea
- Deployment mode(standalone or cluster): standalone
- MQ type(rocksmq, pulsar or kafka): rocksmq
- SDK version(e.g. pymilvus v2.0.0rc2): 2.4.0.dev56

Current Behavior

Create collection will fail using number for int8 field instead of numpy.int8. (int16, int32, float too)

RPC error: [create_collection], <MilvusException: (code=1, message=default value type mismatches field schema type: expected=DataType_Int64, actual=not match: invalid parameter)>, <Time:{'RPC start': '2023-05-30 15:31:40.255728', 'RPC error': '2023-05-30 15:31:40.271251'}>

pymilvus.exceptions.MilvusException: <MilvusException: (code=1, message=default value type mismatches field schema type: expected=DataType_Int64, actual=not match: invalid parameter)>

Expected Behavior

create successfully

Steps To Reproduce

from pymilvus import CollectionSchema, FieldSchema, Collection, connections, DataType, Partition, utility
import numpy as np
import pandas as pd
import random
connections.connect()

# create collection
dim = 128
nb = 300
fields = [
    FieldSchema(name="pk", dtype=DataType.INT64, is_primary=True, description='pk'),
    FieldSchema(name="int8", dtype=DataType.INT8, default_value=8),
    # succeed: FieldSchema(name="int8", dtype=DataType.INT8, default_value=np.int8(8)),
    FieldSchema(name="float_vector", dtype=DataType.FLOAT_VECTOR, dim=dim),
]
schema = CollectionSchema(fields=fields)

collection = Collection("test_default_value", schema=schema)

FieldSchema(name="float", dtype=DataType.FLOAT, default_value=float(3.1415)) -> report error FieldSchema(name="float", dtype=DataType.FLOAT, default_value=np.float32(3.1415)) -> ✅

[smellthemoon]

Yes, this is as expected, when using float(), the type is float64, which is parsed as double when using milvus. The only thing we can do is to check is if we pass in more than the maximum value of this type, whether to report an error. @NicoYuan1986

It's not an error.
