I solved this by adding n_ctx and max_tokens = 256.

Quick fix: remove n_ctx = 256, max_tokens = 256 and change chain_type="stuff" to chain_type="refine"

su77ungr commented 1 year ago

The customLLM.py might be deprecated. I won't include it in the production release. I Instead adding Custom Support to the main startLLM with supported version of LlamaCpp

Keep me posted and thanks for your insights. Maybe we should opt in for a docker release too.

Also, seems like there is no proper stop and start, hence the agent is in a continuous loop of Q&A till it encounters error.

Issue resolved with stable-release?

alxspiker commented 1 year ago

Also increase MODEL_N_CTX in .env if you ever reach the tokens limit again, it increases the context window of 512 error by default to 1000 for both the vector store and the llm model already but can be as high as 9000 in my testing with my unlimited AI tools repo (And honestly don't see a problem as long as your prompt is engineered to give a short answer, the context is only used up by the information from the AI running commands - Must have a decent computer to run very high contexts).

Curiosity007 commented 1 year ago

seems like error is fixed with the new release for now. But I can not stop the model to stop talking on its own. How to do that?

Btw, the original startLLM.py did not work for me. Was throwing syntax error. So , using self modified below version

Tried everything - lowered temp, changed stuff to refine or something else. model does not stop talking immediately. It outputs a self thought chain for a large para, then it stops.

In this Capitol, generation after generation, Americans have debated great questions amid great strife, and have done great things.

We have fought for freedom, expanded liberty, defeated totalitarianism and terror.

And built the strongest, freest, and most prosperous nation the world has ever known.

Now is the hour.

Our moment of responsibility.

Our test of resolve and conscience, of history itself.

> source_documents/state_of_the_union.txt:
And I did that 4 days ago, when I nominated Circuit Court of Appeals Judge Ketanji Brown Jackson. One of our nation’s top legal minds, who will continue Justice Breyer’s legacy of excellence.

> source_documents/state_of_the_union.txt:
I call it building a better America.

My plan to fight inflation will lower your costs and lower the deficit.

17 Nobel laureates in economics say my plan will ease long-term inflationary pressures. Top business leaders and most Americans support my plan. And here’s the plan:

First – cut the cost of prescription drugs. Just look at insulin. One in ten Americans has diabetes. In Virginia, I met a 13-year-old boy named Joshua Davis.

> source_documents/state_of_the_union.txt:
We are cutting off Russia’s largest banks from the international financial system.

Preventing Russia’s central bank from defending the Russian Ruble making Putin’s $630 Billion “war fund” worthless.

We are choking off Russia’s access to technology that will sap its economic strength and weaken its military for years to come.

Tonight I say to the Russian oligarchs and corrupt leaders who have bilked billions of dollars off this violent regime no more.

To stop is from talking on its own for GPT4All() and Llama:

stop: List[str] | None = [],

Example:

LlamaCpp(model_path=local_path, n_ctx=model_n_ctx, stop=["\n"], callbacks=callbacks, verbose=True)

Pretty sure, havnt tested.

alxspiker commented 1 year ago

I am no expert, but I am pretty sure the try except wouldn't catch because I accidentally used a llamacpp model in gpt4all and it just complained about tokens but seems like the script ran as if it did not error.

hippalectryon-0 commented 1 year ago

The newer release should fix the "talking on its own" (don't forget to update your .env and your models as written in the readme)

Curiosity007 commented 1 year ago

Seems like talking on own and context error, both error gone. Closing this issue for now.

I do have one new feature request now - llama GPTQ supports GPU. Will it be possible to incorporate GPU support in this ?

hippalectryon-0 commented 1 year ago

GPU is already supported ;) see the README, it's actually better than GPTQ for small GPUs like mine, since it's CPU+GPU at the same time

The version on main might be missing the env key to add, "N_GPU_LAYERS=..."

Curiosity007 commented 1 year ago

I saw that in the dev branch. GPU part will come soon then.

But I noticed one thing. I deleted all the source documents, recreated the database. Now I want this to talk only on those documents. If it can not find anything , it should say - Nothing found in context.

But right now, model is giving outputs whatever it can. e.g. I kept only 1 pdf with academic formulas. But it is giving me answer on a food recipe, rather than showing it does not find anything in context

hippalectryon-0 commented 1 year ago

Can you open a new issue and share more detail (env, prompt, document) ?

su77ungr commented 1 year ago

@Curiosity007 lower the temperature, reset db.

Edit: add some trickery with the init pompt like "don't respond if you can't answer the question."

Curiosity007 commented 1 year ago

Will try adding that prompt, but seems more stable than before. Thank you for introducing this. This might be the 1st best repo which introduces custom LLMs with custom chatbot function.

Regarding lowering temp and resetting DB, those I had already done. Seems like, prompt tuning and some other environment factor tinkering is required.

On GPU side, I can not see more than 1.4 GB being used, but ideally it should be much more than that. I will wait for full GPU implementation guide.

hippalectryon-0 commented 1 year ago

Don't hesitate to open a new issue, but on my end it can use more than that. Did you adjust N_GPU_LAYERS ?

Curiosity007 commented 1 year ago

Hi, I know this is closed issue, but wanted to ask about feasibility of one thing. Is it possible to incorporate GPTQ models as well? Because in low cpu and high gpu environment, ggml models are being bottle necked by low number of processors

su77ungr commented 1 year ago

see here and switch to GPT4ALL
