ROCM: Garbadge output #33

Slightly better result: |
|
Can you provide the exact model used? It works correctly on my machine: |
|
@ardfork rocm version? GPU? 6_0-bpw-h6 https://huggingface.co/latimar/Synthia-13B-exl2 |
|
I have ROCm 5.6.0 on my host, I have the same nightly PyTorch version as you. Using a 6700 xt with gfx1030 ISA. I only tested Marcoroni-7b-GPTQ, similar to your last test: So, it seems that either something is wrong when running on gfx906 or with your ROCm install. Edit: I also verified that it works correctly with docker.io/rocm/dev-ubuntu-22.04:5.6.1-complete and latest ROCm nightly torch. Maybe try with a container to isolate potential ROCm installation problem. |
GPTQ works on exllama v1. Transformers version works too. |
|
Are you using the same venv, particularly the same pytorch version? I also have heard that sometime gfx906 can have some problem with some optimization level. Can you try replacing |
|
Replacing -03 to -02 or -01 doesn't have any affect, still output garbadge. -00 cause memory access fault (reason: page not present or supervisor privilege) when warmup. |
|
How did you compile exllamav2 to work with ROCm? Or did you just install these:
In advance before installing exllamav2? |
No venv. pytorch system-wide. Other pkgs installed for user.
No noticeable effect with -O1 and -O0. Anyway my GPU works with stable diffusion and exllama v1.
Yes. Just |
|
Since you are not the only one with a gfx906 that have this problem. There is probably something wrong with ROCm and that GPU. Either some emitted code that is incorrect or a builtin function that is broken. I'm curious if it has something to do with one of the half2 functions. Can you try this exllama v1 PR: turboderp/exllama#146? If it produce gibberish we can at least isolate the problem to one of the half2 function. |
Same error in AutoGPTQ/AutoGPTQ#340:
Idk. I have installed AUTOMATIC1111/stable-diffusion-webui and wiki says: For me both Two runs
|
What do you mean same error? It's the first time you are posting that one. This error is because it is based on an older exllama version, it is broken on recent pytorch. Apply the PR on current exllama master or backport this patch turboderp/exllama@3dff8fe.
Exllama always use half, but in exllama v1, it could use half2 and half, half2 were broken (without the PR I linked) so it always used half. Exllama v2 support only half2 (saw some code for half support but don't think it's complete). |
Updated post. I got a little confused responding to different discussions on a similar topic at the same time. |
In commit:
Works, no garbage: |
That just an added comment, the important part was
Interesting, I didn't know about this To go back on your issue, I'm not really sure how to troubleshot it. You could try running with |

Hi, @Jipok. |
No. But I didn’t really look for it due to lack of free time.
Do I understand correctly that this is a server GPU similar to my MI50? In this case, perhaps the problem occurs only on server cards(although rocm usually have problems with desktop cards) |
yes, my device is MI210. |
|
Can confirm the issue still exists today after the pre-build RoCM wheels available. |

I just tested the 2.5bpw Llama2 chat 7B model on my AMD hardware (with llama mode) and it responded like this: Question/Response pairs
Each codeblock was a new chat. It responded very "conservative" and almost always denied the request. However, it seemed to read the input prompt wrong (look at last chat) Inference detailsI had to run it like this: I am not sure if this is a ROCm issue, nor if it is bpw related, when I am home I will compare it to CUDA inference and download all the bpw variants on AMD and NVIDIA (right now I have a a super limited internet connection, I just wanted to document this rn) |
|
It becomes a lot more cooperative with a custom prompt like |

I myself am 99% of the time using exllama on NVIDIA systems, I just wanted to investigate in the amd reliability. I got a better connection here and tested the 4bpw model: mostly unimportantUser: What time is it?

Now it seemed to answer most of the questions but the "alignment" efforts still seem to predominantly peak through for some reason. If this is a non-amd related issue (I will test that in some days when I am back home), maybe this could be mitigated through a good calibration dataset but idk I just wanted to comment my findings. |
|
Just wanted to update that the 4.0bpw works extremely well on AMD hardware, so I apologize for my previous reports. (2.4bpw of the 13b codellama instruct seemed to have the same issues as the llama 7b chat low bpw version) |
|
Your issue have nothing to do with the original one. The problem is that for some reason, exllama v2 produce gibberish on gfx906 (MI50, MI60, Radeon VII, Radeon Pro VII) and gfx90a (MI210, MI250, MI250X). This issue is a duplicate of #15 but provide a bit more information. If AMD GPU have different output or perplexity result than NVIDIA, you should open a different issue. |
|
Mistral consistently produces something similar to a sentence at the beginning. But still a problem. |
|
@Jipok I can not reproduce the issue on MI210 + rocm5.6/5.7 Specifically running https://github.com/PanQiWei/AutoGPTQ/blob/bbbc3c334a35d52d830a5299534d3edfdb268a57/tests/test_q4.py#L374. It is using only a subset of exllama v2 kernels so that may be the reason why. |
|
@fxmarty Hi fxmarty, I just checked with Radeon VII + rocm5.6 with latest exllamav2 code. The issue still exists, so maybe it's something else in the exllamav2 kernel? |
|
Change the warp layout in exllamav2/exllamav2_ext/cuda/rms_norm.cu like #137, from (32,32) to (16,64), can solve this problem. |
|
i can confirm this issue is related to warp size, i can test with many rocm devices (gfx900, gfx906, gfx908, gfx1030) and this issue occures on any device with warp size 64 |
|
I tested my AMD MI25 and MI60 with Mistral-7B-Instruct-v0.2-GPTQ, and the problem still exists. |
|
it certainly is fixed for me on those devices as of 5a61d6e did you compile from recent sources? |
|
I tried to install it from the latest source: And received: `python3 test_inference.py -m /home/dev/test/models/TheBloke_Mistral-7B-Instruct-v0.2-GPTQ -p "hello" hello@ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇ -- Response generated in 5.62 seconds, 128 tokens, 22.79 tokens/second (includes prompt eval.)` |
|
might be something that only shows in minstal, could you try a llama(v2) based model to narrow it down? |
|
I have tried TheBloke_Dolphin-Llama2-7B-GPTQ, TheBloke_WizardLM-7B-uncensored-GPTQ, and TheBloke_Mistral-7B-Instruct-v0.2-GPTQ. Almost identical result. Just a bunch of "⁇ ⁇ ⁇ ⁇ ⁇ ⁇ ⁇". Dolphin-Llama2 starts with some text, but after several words starts printing "⁇ ⁇ ⁇." |
|
what rocm version are you using and is the mi25 and the mi60 in the same system? |
|
I tried Llama-2-7B-Chat-fp16, and it works perfectly on both mi25 and mi60 |
|
That means the normalization kernel works, at least. It's hard to say what else might be acting up. You can try disabling flash-attn with This will run both models in parallel and compare the hidden state between each, and while the difference is likely going to explode, it would be helpful to know when it happens exactly, i.e. if it's after an attention or MLP block. |
|
@turboderp I want to share my mi60 for debugging. How can I contact you? |
|
@turboderp @ZanMax I have a dual mi60 system and am having the exact same issue with the question marks. Same thing when manually updating exllamav2 and using it inside of text-generation-webui as well. |
|
I have a 7900XTX on order now. Once it arrives I can start doing some ROCm testing myself. Give it a few more days. |
|
Cool sounds good. I can get you an SSH key to my dual mi60 machine too, if you want. It more or less stays on 24/7 |
|
@turboderp you might want a wave64 device to (ie a old consumer card or mi25-mi300) i would be willing to provide a mi25 free of charge if you are in Europe. |
|
Was this ever investigated any further? |
|
I'm going to close this issue here since it seems to be stale, but please open a new issue if there continues to be issues with wave64 cards. |
GPTQ models works with exllama v1.
