Declaration of structure 1.1 Basic knowledge of structures A structure is a collection of values called member variables. Each member of the […]

Large language model 16 – long text context fine-tuning Llama-2 based on LongLoRA

Increasing the LLM context length can improve the performance of large language models on some tasks, including multi-round long conversations, long text summaries, high-resolution 4k model understanding of the visual-linguistic Transformer model, code generation, image and audio generation, etc. For long context scenarios, in the decoding stage, caching the Key and Value (KV) of the […]

Langchain-Chachat Project: 2.1 – Retrieving NebulaGraph via GPT2 model

The official example shows how to retrieve the NebulaGraph graph database through chain = NebulaGraphQAChain.from_llm(ChatOpenAI(temperature=0), graph=graph, verbose=True). This article introduces the idea and implementation of replacing ChatOpenAI through GPT2, without considering the effect for the time being. The reason why ChatGLM2 is not used is that loading the model is too slow and debugging is […]
