Tried both bitsandbytes 4 bit & 8 bit quantization, not worked. Memory cost is still same to bf16

Tried both bitsandbytes 4 bit & 8 bit quantization, not worked. Memory cost is still same to bf16

how to load this model in 8bit?

I should have read this here first! https://github.com/TimDettmers/bitsandbytes/issues/1155

I change the model format using this script:

import json
from safetensors import safe_open
from safetensors.torch import save_file
from pathlib import Path

model_dir = Path('your_model_dir')
output_dir = Path('your_output_dir')

NUM_EXPERTS = 16
HIDDEN_SIZE = 6144
FFN_HIDDEN_SIZE = 10752

def change_tensor(tensor, reverse=False):

    output = [x.contiguous() if not reverse else x.t().contiguous() for x in tensor.reshape(NUM_EXPERTS, FFN_HIDDEN_SIZE, HIDDEN_SIZE)]

    return output

def change_mlp(tensors):

    keys = list(tensors.keys())
    for k in keys:
        if any([x in k for x in ['w1', 'v1', 'w2']]):
            prefix,dtype = k.rsplit('.', 1)
            tensor = tensors.pop(k)
            output_tensor = change_tensor(tensor, dtype=='w2')
            for i,t in enumerate(output_tensor):
                tensors[f'{prefix}.{i}.{dtype}.weight'] = t

    return tensors

for file in model_dir.glob('*.safetensors'):
    print(file)
    tensors = {}
    with safe_open(file, 'pt') as f:
        metadata = f.metadata()
        for k in f.keys():
            tensors[k] = f.get_tensor(k)
    tensors = change_mlp(tensors)
    save_file(tensors, (output_dir / file.name).as_posix(), metadata)

with open(model_dir / 'model.safetensors.index.json') as f:
    weight_map = json.load(f)

weight_keys = list(weight_map['weight_map'])
for k in weight_keys:
    if any([x in k for x in ['w1', 'v1', 'w2']]):
        prefix,dtype = k.rsplit('.', 1)
        value = weight_map['weight_map'].pop(k)
        for i in range(NUM_EXPERTS):
            weight_map['weight_map'][f'{prefix}.{i}.{dtype}.weight'] = value

sorted_map = sorted(list(weight_map['weight_map'].items()))
weight_map['weight_map'] = dict(sorted_map)

with open(output_dir / 'model.safetensors.index.json', 'w') as f:
    json.dump(weight_map, f, indent=4)

Then, inside file modeling_dbrx.py I change some here:

I tried something very similar to the above last night, on my own, and can confirm it works. Once the experts are just normal nn.Linear layers they can be loaded with 4 bit quantization. Well, the model "works" in the sense that when you load it in 4 bit it's mostly okay, but will frequently misspell words, double up commas, output random garbage tokens, etc. So something is still off about it (might just be unusually sensitive to load_in_4bit quantization).

Would be nice if we could get some way to do this officially. Otherwise, I imagine someone will upload a model with these changes, and lots of people will just use that version, as you can train LoRA on it etc. Alternatively, bitsandbytes and PEFT would have to add explicit support somehow for the current fused weight architecture.

I uploaded an adjusted version based on the code from fahadh4ilyas, so people don't need to make the changes manually. Thank you so much for the scripts and the adjustments. Here is the model: SinclairSchneider/dbrx-instruct-quantization-fixed

@SinclairSchneider can you please upload the 4bit quantized version of the model? Thanks!

Thank you! so this is a 8bit version?

Also, can you please share how the 4-bit/8-bit quantized model is performing? Thanks!

Based on the file size, it is the original model with bf16.

It's not quantized but you can use "load_in_4bit=True" or "load_in_8bit=True" without running into out of memory issues like when using the original model.

Thanks! Understood

@SinclairSchneider is it possible for you to quantized the model using that option? Since you are loading the model in 4bit mode, I think the script is converting the model to 4 bits on the fly which means you can do the same for generating the quantized model files.

In my case, it works quite well. I literally only change nn.Parameter into nn.Linear. Even when load it in cpu without quantization and generate using it, the generation result is no different with this repo.

@fahadh4ilyas You are awesome! Anyone interested, the dbrx-instruct converted model is currently getting uploaded to hf 33% complete:

Hi @fahadh4ilyas , I have tried your modification but have this error:

 File "modeling_dbrx.py", line 642, in __init__
    self.norm_1 = nn.LayerNorm(hidden_size, bias=False)
TypeError: __init__() got an unexpected keyword argument 'bias'

Hi @fahadh4ilyas , I have tried your modification but have this error:

 File "modeling_dbrx.py", line 642, in __init__
    self.norm_1 = nn.LayerNorm(hidden_size, bias=False)
TypeError: __init__() got an unexpected keyword argument 'bias'

I think you have to update your torch. Because that error implied that nn.LayerNorm has no bias parameter in its init method. But, from torch documentation here, clearly bias exists there.

@fahadh4ilyas Thanks for the clarification! I think now I can load the model in 4 bit, taking ~71G ram in total, but the loading is very slow. The generation also contains many random and garbage tokens.

dbrx-base-converted now on hf: https://huggingface.co/LnL-AI/dbrx-base-converted

(pending upload...should be complete in about 10 minutes). I have cancelled the broken upload of instruct-converted model now that base is here.

bnb 4 bit version can be found here: https://huggingface.co/PrunaAI/dbrx-base-bnb-4bit

dbrx-base-converted-v2 now on hf: https://huggingface.co/LnL-AI/dbrx-base-converted-v2 with Wqkv split into q, k, v for potentially better quant compatible. exllama v2 latest code also does this split. Testing and quant has not been verified yet.

Again thanks to @fahadh4ilyas for the v2 changes.

bnb 4 bit version can be found here: https://huggingface.co/PrunaAI/dbrx-base-bnb-4bit

Is there bnb 4bit for dbrx-instruct? The base model is not good at instruction following. Thanks!

@MLDataScientist 4bit quant is available for apple mlx (but need like m ultra) and exllama v2 has it too. But if you want base to instruct follow, it doesn't do that. It is base vs instruct for good reason.

I know, right! That is why I needed the instruct bnb 4bit. Fortunately, we already have it as @johnrachwanpruna mentioned above.

@johnrachwanpruna , Is this dbrx-instruct converted using the method described by @fahadh4ilyas ?

Yes exactly :)

@fahadh4ilyas @Qubitium Looks like the converted models don't play nice with 4bit-qlora+fsdp:

Which model are you using? v1 or v2?

@fahadh4ilyas @winglian was using v2 for that crash
