How to save and load a database from local in mem0？

[lemon-little]

Issue with current documentation:

Like embedchain reuse a vector database reuse embeddding

My code:

config = {
    "llm": {
        "provider": "openai",
        },
    "embedder": {
        "provider": "openai" 
        },
    "history_db_path": "/home/lcy/.mem0/history.db",
    "vector_store": {
        "provider": "qdrant",
        "config": {
            "host": "localhost",
            "path": "/tmp/qdrant",
            "collection_name": "mem0",
        }
    }
}
memory = Memory().from_config(config)
all_memories = memory.get_all()

I can't reuse the local memory with the same code when I run the code.

Hey @lemon-little You actually can reuse the local memory but make sure the Memory is not initialized again, because that will recreate a new collection. @zhurou603 You can also try the same approach.

Let me know if you still face any issues.

I can not understand 'local memory' means, I want to save my collections into disk(instead of memory), and close current process, maybe another process can load this collection.

Hey @lemon-little You actually can reuse the local memory but make sure the Memory is not initialized again, because that will recreate a new collection. @zhurou603 You can also try the same approach.嘿，@lemon小你实际上可以重用本地内存，但请确保内存不会再次初始化，因为这将重新创建一个新的集合。@zhurou603您也可以尝试相同的方法。

Let me know if you still face any issues.如果您仍然遇到任何问题，请告诉我。

But another process can't load the collection.

@lemon-little Please visit this doc and set on_disk param to True for persistent storage.
