Models not responding (No AVX Support)

JeshMate commented 1 year ago

Not sure if im doing something wrong but when i send a request through curl to the api, it does this:

It doesn't go past this whatsoever, I'm new to this whole thing, so far I built the binary by itself but the same thing would happen in docker too.

If there's anything that needs to be supplied, let me know.

JeshMate commented 1 year ago

im actually starting to guess it might be because the lack of avx support on the cpus im using which would be causing this problem

I am seeing the problem using an M1 Max Macbook Pro / Ventura 13.3.1 / Docker 4.17.0 (99724).

Exactly same issue on M1 Pro 32 gb, Docker version 20.10.24, build 297e128, Ventura 13.3.1 (22E261). Tried with different models, just nothing happens: no errors, no timeouts.

hatsoever, I'm new to this whole thing, so far I built the binary by itself, but the same thing would happen in docker too.

@JeshMate , This could very well be the case. I ran the same container in two different hosts, one with AVX and another without it; the one with AVX works the other one does not. This is the output of docker logs in the one that works

i did see that there are ways to run it without avx but it does consume a lot more resources and also requires rebuilding the binaries behind it, i have no idea what settings to use and hopefully the repo host could guide us in the right way.

Hey all :wave: very well detective work here!

Docs are lacking here, so my bad. Until we get that's fixed let me give some hints:

If you don't have AVX, inference will be very slow, however you can build the image locally with "BUILD_TYPE=generic" as docker build arg. - I will fix the examples in the repos soon
If on mac(arm-based), don't use docker. It will be much slower - so better just run make build and compile it locally until we have #66 fixed.
You can turn "DEBUG=true" or pass --debug to enable debug logging to increase logs verbosity.

JeshMate commented 1 year ago

Okie dokie!

Just wondering, because I didn't really want to use docker regardless for something like this, I built a local binary with make build within the cloned git repo on machine, loaded the gglm-gpt4all-j model and it doesn't seem to crash but I sat and waited for a good hour and still nothing, I'm guessing that if I want a response within a reasonable time, I must use a machine with AVX I presume?

If nothing seems to be working, I'm happy to wait until the docs get updated to support environments like this so we've got more of an understanding to how stuff like this can be used.

Fantastic work on this by the way!

P.S, Didn't mean to close the thread lol, still new to github.

After using make build then make run:

curl http://localhost:8080/v1/models {"object":"list","data":[{"id":".DS_Store","object":"model"},{"id":".devcontainer","object":"model"},{"id":".dockerignore","object":"model"},{"id":".env","object":"model"},{"id":".git","object":"model"},{"id":".github","object":"model"},{"id":".gitignore","object":"model"},{"id":".vscode","object":"model"},{"id":"Dockerfile","object":"model"},{"id":"Earthfile","object":"model"},{"id":"LICENSE","object":"model"},{"id":"Makefile","object":"model"},{"id":"README.md","object":"model"},{"id":"api","object":"model"},{"id":"charts","object":"model"},{"id":"examples","object":"model"},{"id":"go-gpt2","object":"model"},{"id":"go-gpt4all-j","object":"model"},{"id":"go-llama","object":"model"},{"id":"go.mod","object":"model"},{"id":"go.sum","object":"model"},{"id":"local-ai","object":"model"},{"id":"main.go","object":"model"},{"id":"models","object":"model"},{"id":"pkg","object":"model"},{"id":"prompt-templates","object":"model"},{"id":"renovate.json","object":"model"},{"id":"tests","object":"model"},{"id":"","object":"model"}]}%

I also tried using go-gpt4all-j, go-gpt2 and go-llama as the model in the above curl.

I then tried downloading the https://gpt4all.io/models/ggml-gpt4all-j.bin model:

# Download gpt4all-j to models/
wget https://gpt4all.io/models/ggml-gpt4all-j.bin -O models/ggml-gpt4all-j

# Use a template from the examples
cp -rf prompt-templates/ggml-gpt4all-j.tmpl models/

Then running make build and make run, but still it shows 'model does not exist'.

MartyLake commented 1 year ago

@pobmob to run locally, you have to specify the --models-path

./local_ai --models-path models/

or change directory to /models before running:

cd models
../local_ai

pobmob commented 1 year ago

Thanks @MartyLake

./local-ai --models-path models/

Got things working for me.

Although I still noticed the model had 'unexpectedly reached end of file' using the make build process.

curl http://localhost:8080/v1/models

Even with the error above, I am now getting a response using curl.

     "model": "ggml-gpt4all-j",

However, I would be happy to help you with that."}}]}%

Anybody know where the task "need to make a list of all the cities in the world" came from? Has it just made that up/hallucinated?

I am using the ggml-alpaca-7b-q4 model now and for my usage it works so good on my M1 Max 32GB Macbook Pro.

dannyvfilms commented 1 year ago

I'm confused on if different installation instructions need to be added to the Readme for AVX vs Non-AVX or if we need to wait for a fix. I'm having what I believe to be a similar issue error loading model: unexpectedly reached end of file problem on a Ryzen 5 4600 on Unraid:

Oddly in my case it worked for a bit until I tried a large payload, and now after restarting and recreating the container it won't work at all. I'm hoping it's related to this issue, but I can start a new issue if it turns out it isn't related.

LarsBingBong commented 1 year ago

I'm running this on a K3s v1.25.5+k3s1 cluster. On VMWare. I controlled whether the CPU's dedicated to the VM supports avx by executing: grep -o -w 'avx\|avx2\|avx512' /proc/cpuinfo.

And the output:

avx
avx2
avx
avx2
avx
avx2
avx
avx2
avx
avx2
avx
avx2

So the answer is yes. However, e.g. executing:

curl http://local-ai.ai-llm.svc.cluster.local:8080/v1/chat/completions -H "Content-Type: application/json" -d '{
     "model": "ggml-gpt4all-j.bin",
     "messages": [{"role": "user", "content": "How are you?"}],
     "temperature": 0.9 
   }'

Towards the Local-AI Pod gives me no answer. I've waited for more than 10 minutes over several tries.

I also see the: local-ai error loading model: unexpectedly reached end of file error in the Local-AI Pod.

Other notes:

The worker the Local-AI Pod ended up on the initial cluster whereon I tried this. "Only" have 6 vCPU's. And the Local-AI Pod IS using almost all of that ... do I need to give it more juice?

For good measure I tried on a cluster with 8 vCPU's dedicated and double up on RAM/MEMORY on the workers.

And the result: Bad. Couldn't even install. So....

Hmm I've not always been impressed with the IOPS that the Longhorn CSI can give. ( They're looking into it and are switching to SPDK in the next version ). So might this be a under performing disk setup. I guess that Local-AI of course needs to read the model at a certain speed form the deployed PVC?

Therefore I created a new Longhorn StorageClass that specifies one replica and strict locality ( so that the volume is on the same node as the Pod mounting it ).

Result: I could now install the Local-AI Helm Chart.

Testing with:

curl http://local-ai.ai-llm.svc.cluster.local:8080/v1/chat/completions -H "Content-Type: application/json" -d '{
     "model": "ggml-gpt4all-j.bin",
     "messages": [{"role": "user", "content": "How are you?"}],
     "temperature": 0.9 
   }'

I see the model loading >> and still the error loading model: unexpectedly reached end of file and the "How are you" prompt is hanging for a long time ....

The Local-AI process is now maxing out the 8 vCPU's over 15 threads. But, NO answer after having waited for more than 10 minutes.

I also executed grep -o -w 'avx\|avx2\|avx512' /proc/cpuinfo inside the Local-AI Pod and the result is the same as on the worker node itself. AVX is enabled.

I therefore enabled debug logging to get some more info. This by editing the Local-AI Deployment on the cluster whereon it was running.

So:

spec:
  progressDeadlineSeconds: 600
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      app.kubernetes.io/instance: local-ai
      app.kubernetes.io/name: local-ai
  strategy:
    rollingUpdate:
      maxSurge: 25%
      maxUnavailable: 25%
    type: RollingUpdate
  template:
    metadata:
      creationTimestamp: null
      labels:
        app.kubernetes.io/instance: local-ai
        app.kubernetes.io/name: local-ai
      name: local-ai
    spec:
      containers:
      - args:
        - --debug
        command:
        - /usr/bin/local-ai
....
....
....
....

And here's the result >> Still hanging and no response.

Looked into my options in regards to how the API can be requested. So tried a simpler query.

curl http://local-ai.ai-llm.svc.cluster.local:8080/v1/completions -H "Content-Type: application/json" -d '{
     "model": "ggml-gpt4all-j.bin",
     "prompt": "How are you?",
     "temperature": 0.7 
   }'

However, the picture remains, No response and full CPU exhaustion on the worker.

Trying with more tokens.

curl http://local-ai.ai-llm.svc.cluster.local:8080/v1/completions -H "Content-Type: application/json" -d '{
     "model": "ggml-gpt4all-j.bin",
     "prompt": "How are you?",
     "temperature": 0.7,
     "max_tokens": 1536
}'

Result: Waited for more than 10 minutes ... no answer

Other notes

I've experienced that the Local-AI process seems not to release the CPU. At least not after the first couple of minutes after having canceled one of the above cURL examples.

For good measure here are the Local-AI debug logs

9:50AM DBG Request received: {"model":"ggml-gpt4all-j.bin","prompt":"How are you?","stop":"","messages":null,"stream":false,"echo":false,"top_p":0,"top_k":0,"temperature":0.7,"max_tokens":1536,"n":0,"batch":0,"f16":false,"ignore_eos":false,"repeat_penalty":0,"n_keep":0,"seed":0}

I really hope this can be fixed/get working ... as this really have promise and is exciting.

Thank you very much to you all.

I'm getting the same issue but the CPU I'm running on does support AVX/AVX2 but not AVX512

Does this require AVX2 or AVX512 explicitly ?

Intel has removed AVX512 support on consumer cpu's

faust93 commented 1 year ago

CPU Ryzen 5 4600G with AVX2, plain build (no docker). According to CPU usage it does something, waited for 10 min but got no response..

mudler commented 1 year ago

the issue with @LarsBingBong was resolved over discord and was threads overbooking. lowering the number of threads to physical cores was the issue in his case - can you try specifying a lower number of threads?

kub3let commented 1 year ago

The issue is fixed by latest 1.5.1 docker image for me :)

ksingh7 commented 1 year ago

1) I am still wondering why it always throw this error ?

2) i am running the latest docker image quay.io/go-skynet/local-ai as of 3rd May , and i can confirm that response from API is coming, however its ultra slow. This is on AWS t3a.xlarge instance type (4vcpu , 16gMemory, AVX, AVX2 support) Amazon Linux , running with `--threads 8``

Does anyone know how to speed things up , should i bump up the instance type, would it help ?

That is definitely too much, this is my output:

I also get that exact error about the unexpected end of file. In AWS, I'm using m5.xlarge.

The error on the llama.cpp backend is on the first-load of the model. If you don't specify a backend in the model config file, the first load is greedy and will try to load a model from any of the backends. (see here https://github.com/go-skynet/LocalAI#advanced-configuration on how to do that )

I think the real problem here is that you have a 4vcpu, so you should lower the threads - at least at 4cores. But I wouldn't expect fast responses on small droplets. You should probably for rwkv models instead.

:warning::warning::warning::warning::warning:

Hi! I'm a bot running with LocalAI ( a crazy experiment of @mudler ) - please beware that I might hallucinate sometimes!

_but.... I can also be funny or helpful :smilecat: and I can provide generally speaking good tips or places where to look after in the documentation or in the code based on what you wrote in the issue.

Don't engage in conversation with me, I don't support (yet) replying!

:warning::warning::warning::warning::warning:

I can see from the image you provided that the issue is with the request body. The prompt parameter should be a string that describes what the model should generate text for. In your case, it seems like the prompt is not formatted correctly. Please check the request body and make sure to include the prompt parameter in the correct format.

closing this as not relevant anymore. Many things changed meanwhile and support for old CPU with missing flags is now documented in the build section of our docs https://localai.io/basics/build/
