I want to ask

self.collection = Collection(collection_name)

self.collection.load()

self.collection_index_schema = self.collection.indexes[0]

self.collection_index_schema._index_params['index_type']

Sometimes key error occurs but sometimes it works. How to solve it?

Hello @dkchung0! I'm here to assist you with any bugs, questions, or contributions you may have. Let's work together to resolve any issues you're encountering.

A KeyError when accessing _index_params in a Milvus index schema can occur if the index parameters are not properly set or if the index creation fails. Here are a few things to consider:

1. Index Creation: Ensure that the index is created successfully with the correct parameters. If the index type or other parameters are incorrect, the index might not be created, leading to missing _index_params.

2. Collection Load State: Make sure the collection is properly loaded before accessing the index parameters. If the collection is not fully loaded, the index parameters might not be available.

3. Index Schema Updates: If there are any updates or changes to the index schema, ensure that the collection is released before making changes, as Milvus does not allow altering index properties on a loaded collection ^[1].

4. Intermittent Issues: If the issue is intermittent, it might be related to the environment or specific conditions under which the index is accessed. Double-check the consistency of the environment and any conditions that might affect the index loading or creation.

If these steps do not resolve the issue, further investigation into the specific conditions and environment might be necessary.
