# BigScience's BLOOMZ 176B GPTQ
These files are GPTQ 4bit model files for [BigScience's BLOOMZ](https://huggingface.co./bigscience/bloomz).
It is the result of quantising to 4bit using [AutoGPTQ](https://github.com/PanQiWei/AutoGPTQ).
**This is a BIG model! 2 x 80GB or 3 x 48GB GPUs are required**
## Important note: files must be joined before use
It is not currently possible to shard GPTQ files, therefore the model file is one single 100+GB file.
Huggingface Hub has a 50GB per-file limit. I have therefore been forced to split the file in to three parts for upload.
I did this using the simple *nix command `split`.
To join the files on any *nix system, run:
```
cat gptq_model-4bit--1g.JOINBEFOREUSE.split-*.safetensors > gptq_model-4bit--1g.safetensors
```
To join the files on Windows, open a Command Prompt and run:
```
COPY /B gptq_model-4bit--1g.JOINBEFOREUSE.split-a.safetensors + gptq_model-4bit--1g.JOINBEFOREUSE.split-b.safetensors + gptq_model-4bit--1g.JOINBEFOREUSE.split-c.safetensors gptq_model-4bit--1g.safetensors
```
The SHA256SUM of the joined file will be:
```
50baeab9859362d22df6f822f158b9ba75b44ffc6605b715992fe6245aa6e93a gptq_model-4bit--1g.safetensors
```
Once you have the joined file, you can safely delete `gptq_model-4bit--1g.JOINBEFOREUSE.split-*.safetensors`.
## Repositories available
* [4-bit GPTQ model for GPU inference](https://huggingface.co./TheBlokeAI/bloomz-175B-GPTQ)
* [Unquantised fp16 model in pytorch format, for GPU inference and for further conversions](https://huggingface.co./bigscience/bloomz)
## Two files provided - separate branches
- Main branch: `gptq_model-4bit--1g.safetensors`
- Group Size = None
- Desc Act (act-order) = True
- This version will use the least possible VRAM, and should have higher inference performance in CUDA mode
- Branch `group_size_128g`: `gptq_model-4bit-128g.safetensors`
- Group Size = 128g
- Desc Act (act-oder) = True
- This version will use more VRAM, which shouldn't be a problem as it shouldn't exceed 2 x 80GB or 3 x 48GB cards.
- However CUDA inference performance is likely to be a lot slower, possibly necessitating the use of Triton mode.
By default you will download the first file, unless you choose to download from branch `group_size_128g`.

## How to easily download and use this model in text-generation-webui
Please make sure you're using the latest version of text-generation-webui.
Note 1: this is a non-Llama model which cannot be used with ExLlama. Use Loader: AutoGPTQ.
Note 2: As described above, you must join the files after downloading and before loading in text-generation-webui.
1. Click the **Model tab**.
2. Under **Download custom model or LoRA**, enter `TheBloke/bloomz-176B-GPTQ`.
- If you would rather download the group_size 128g version, enter `TheBloke/bloomz-176B-GPTQ:group_size_128g`
3. Click **Download**.
4. The model will start downloading. Once it's finished it will say "Done". This is a huge model so it may take a while!
5. Now follow the steps described above to join the model to get a single `.safetensors` file.
6. Untick **Autoload model**
7. In the top left, click the refresh icon next to **Model**.
8. In the **Model** dropdown, choose the model you just downloaded: `bloomz-176B-GPTQ`
9. Make sure Loader is set to AutGPTQ.
10. This model cannot load on one GPU, so you should set **GPU Memory** accordingly.
- If using two 80GB GPUs, try: GPU0 = 60GB, GPU1 = 79GB
- If using three 48GB GPUs, try: GPU0 = 30GB, GPU1 = 47GB, GPU2 = 47GB
11. Click **Save settings** to save your settings, and then **Reload** to load the model.
12. The model will load, and is now ready for use!
13. Once you're ready, click the **Text Generation tab** and enter a prompt to get started!
## How to use this GPTQ model from Python code
First make sure you have [AutoGPTQ](https://github.com/PanQiWei/AutoGPTQ) installed:
`GITHUB_ACTIONS=true pip install auto-gptq`
Because this model has to be joined locally, you must first download it. Example download code:
```python
from huggingface_hub import snapshot_download
snapshot_download(repo_id="TheBloke/bloomz-176B-GPTQ",
local_dir="/workspace/models/bloomz-176GB-GPTQ",
local_dir_use_symlinks=False)
```
If you want to download the group_size 128g file instead, add `revision="group_size_128g"` to the above command.
Now join the three `split` files up as described above, to get a single `safetensors` file.
Then try the following example code:
```python
from transformers import AutoTokenizer, pipeline, logging
from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig
import argparse
# Use the local path you downloaded the model to and joined the split files in
model_name_or_path = "/workspace/models/bloomz-176GB-GPTQ"
model_basename = "gptq_model-4bit--1g"
use_triton = False
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, use_fast=True)
model = AutoGPTQForCausalLM.from_quantized(model_name_or_path,
model_basename=model_basename,
max_memory={0: '60GiB', 1: '79GiB'} # max_memory is for 2 x 80GB GPUs; adjust if your config is different!
use_safetensors=True,
trust_remote_code=False,
use_triton=use_triton,
quantize_config=None)
prompt = "Translate this to French: AI is the future of computing"
prompt_template=f'''{prompt}
Translation:
'''
print("\n\n*** Generate:")
input_ids = tokenizer(prompt_template, return_tensors='pt').input_ids.cuda()
output = model.generate(inputs=input_ids, temperature=0.7, max_new_tokens=512)
print(tokenizer.decode(output[0]))
# Inference can also be done using transformers' pipeline
# Prevent printing spurious transformers error when using pipeline with AutoGPTQ
logging.set_verbosity(logging.CRITICAL)
print("*** Pipeline:")
pipe = pipeline(
"text-generation",
model=model,
tokenizer=tokenizer,
max_new_tokens=512,
temperature=0.7,
top_p=0.95,
repetition_penalty=1.15
)
print(pipe(prompt_template)[0]['generated_text'])
```
## Provided files
## Main branch:
**gptq_model-4bit--1g.safetensors**
This will work with AutoGPTQ. It is untested with GPTQ-for-LLaMa. It will *not* work with ExLlama.
It was created with group_size none (-1) to reduce VRAM usage, and with --act-order (desc_act) to increase inference speed.
* `gptq_model-4bit-128g.safetensors`
* Works with AutoGPTQ in CUDA or Triton modes.
* Does NOT work with [ExLlama](https://github.com/turboderp/exllama) as it's not a Llama model.
* Works with GPTQ-for-LLaMa in CUDA mode. May have issues with GPTQ-for-LLaMa Triton mode.
* Works with text-generation-webui, including one-click-installers.
* Parameters: Groupsize = -1. Act Order / desc_act = True.
## Branch `group_size_128g`
**gptq_model-4bit-128g.safetensors**
This will work with AutoGPTQ. It is untested with GPTQ-for-LLaMa. It will *not* work with ExLlama.
It was created with both group_size 128g and --act-order (desc_act) for increased inference quality.
**Note** Using group_size + desc_act together can significantly lower performance in AutoGPTQ CUDA. You might want to try AutoGPTQ Triton mode instead (Linux only.)
* `gptq_model-4bit-128g.safetensors`

* Does NOT work with [ExLlama](https://github.com/turboderp/exllama) as it's not a Llama model.
* Untested with GPTQ-for-LLaMa.
* Works with text-generation-webui, including one-click-installers.
* Parameters: Groupsize = 128. Act Order / desc_act = True.
