# Mamba
|
||||
|
||||
<!-- Provide a quick summary of what the model is/does. -->
|
||||
This repository contains the `transfromers` compatible `mamba-2.8b`. The checkpoints are untouched, but the full `config.json` and tokenizer are pushed to this repo.
|
||||
|
||||
# Usage
|
||||
|
||||
You need to install `transformers` from `main` until `transformers=4.39.0` is released.
|
||||
```bash
|
||||
pip install git+https://github.com/huggingface/transformers@main
|
||||
```
|
||||
|
||||
We also recommend you to install both `causal_conv_1d` and `mamba-ssm` using:
|
||||
|
||||
```bash
|
||||
pip install causal-conv1d>=1.2.0
|
||||
pip install mamba-ssm
|
||||
```
|
||||
|
||||
If any of these two is not installed, the "eager" implementation will be used. Otherwise the more optimised `cuda` kernels will be used.
|
||||
|
||||
## Generation
|
||||
You can use the classic `generate` API:
|
||||
```python
|
||||
>>> from transformers import MambaConfig, MambaForCausalLM, AutoTokenizer
|
||||
>>> import torch
|
||||
|
||||
>>> tokenizer = AutoTokenizer.from_pretrained("state-spaces/mamba-2.8b-hf")
|
||||
>>> model = MambaForCausalLM.from_pretrained("state-spaces/mamba-2.8b-hf")
|
||||
>>> input_ids = tokenizer("Hey how are you doing?", return_tensors="pt")["input_ids"]
|
||||
|
||||
>>> out = model.generate(input_ids, max_new_tokens=10)
|
||||
>>> print(tokenizer.batch_decode(out))
|
||||
["Hey how are you doing?\n\nI'm doing great.\n\nI"]
|
||||
```
|
||||
|
||||
## PEFT finetuning example
|
||||
In order to finetune using the `peft` library, we recommend keeping the model in float32!
|
||||
|
||||
```python
|
||||
from datasets import load_dataset
|
||||
from trl import SFTTrainer
|
||||
from peft import LoraConfig
|
||||
from transformers import AutoTokenizer, AutoModelForCausalLM, TrainingArguments
|
||||
tokenizer = AutoTokenizer.from_pretrained("state-spaces/mamba-2.8b-hf")
|
||||
model = AutoModelForCausalLM.from_pretrained("state-spaces/mamba-2.8b-hf")
|
||||
dataset = load_dataset("Abirate/english_quotes", split="train")
|
||||
training_args = TrainingArguments(
|
||||
output_dir="./results",
|
||||
num_train_epochs=3,
|
||||
per_device_train_batch_size=4,
|
||||
logging_dir='./logs',
|
||||
logging_steps=10,
|
||||
learning_rate=2e-3
|
||||
)
|
||||
lora_config = LoraConfig(
|
||||
r=8,
|
||||
target_modules=["x_proj", "embeddings", "in_proj", "out_proj"],
|
||||
task_type="CAUSAL_LM",
|
||||
bias="none"
|
||||
)
|
||||
trainer = SFTTrainer(
|
||||
model=model,
|
||||
tokenizer=tokenizer,
|
||||
args=training_args,
|
||||
peft_config=lora_config,
|
||||
train_dataset=dataset,
|
||||
dataset_text_field="quote",
|
||||
)
|
||||
trainer.train()
|
||||
```
