## Installation

The following requirements should be satisfied
- [PyTorch](https://pytorch.org/) >= 2.5
- [Triton](https://github.com/openai/triton) >=3.0 (or nightly version, see [FAQs](FAQs.md))
- [einops](https://einops.rocks/)
- [transformers](https://github.com/huggingface/transformers) >=4.45.0

- [causal-conv1d](https://github.com/Dao-AILab/causal-conv1d) >=1.4.0

As `fla` is actively developed now, no released packages are provided at this time.
If you do need to use `fla` ops/modules and contemplate further explorations, an alternative way is to install the package from source
```sh
# uninstall `fla` first to ensure a successful upgrade
pip uninstall fla && pip install -U git+https://github.com/fla-org/flash-linear-attention
```
or manage `fla` with submodules
```sh
git submodule add https://github.com/fla-org/flash-linear-attention.git 3rdparty/flash-linear-attention
ln -s 3rdparty/flash-linear-attention/fla fla
```

## Usage

### Token Mixing

We provide ``token mixing'' linear attention layers in `fla.layers` for you to use.
You can replace the standard multihead attention layer in your model with other linear attention layers.
Example usage is as follows:
```py
>>> import torch
>>> from fla.layers import MultiScaleRetention
>>> batch_size, num_heads, seq_len, hidden_size = 32, 4, 2048, 1024
>>> device, dtype = 'cuda:0', torch.bfloat16
>>> retnet = MultiScaleRetention(hidden_size=hidden_size, num_heads=num_heads).to(device=device, dtype=dtype)
>>> retnet
MultiScaleRetention(
  (q_proj): Linear(in_features=1024, out_features=1024, bias=False)
  (k_proj): Linear(in_features=1024, out_features=1024, bias=False)
  (v_proj): Linear(in_features=1024, out_features=2048, bias=False)
  (g_proj): Linear(in_features=1024, out_features=2048, bias=False)
  (o_proj): Linear(in_features=2048, out_features=1024, bias=False)
  (g_norm_swish_gate): FusedRMSNormSwishGate(512, eps=1e-05)
  (rotary): RotaryEmbedding()
)
>>> x = torch.randn(batch_size, seq_len, hidden_size).to(device=device, dtype=dtype)
>>> y, *_ = retnet(x)
>>> y.shape
torch.Size([32, 2048, 1024])
```

We provide the implementations of models that are compatible with 🤗 Transformers library.
Here's an example of how to initialize a GLA model from the default configs in `fla`:

```py
>>> from fla.models import GLAConfig

### Fused Modules

We offer a collection of fused modules in `fla.modules` to facilitate faster training:

* [`Rotary Embedding`](fla/modules/rotary.py): rotary positional embeddings as adopted by the Llama architecture, a.k.a., Transformer++.
* [`Norm Layers`](fla/modules/layernorm.py):
  * `RMSNorm`, `LayerNorm` and `GroupNorm`
  * `RMSNormLinear`, `LayerNormLinear` and `GroupNormLinear` to reduce memory usage of intermediate tensors for improved memory efficiency.
* [`Norm Layers with Gating`](fla/modules/fused_norm_gate.py): combine norm layers with element-wise gating, as used by RetNet/GLA.
* [`Cross Entropy`](fla/modules/fused_cross_entropy.py): faster Triton implementation of cross entropy loss.
* [`Linear Cross Entropy`](fla/modules/fused_linear_cross_entropy.py): fused linear layer and cross entropy loss to avoid the materialization of large logits tensors. Also refer to implementations by [mgmalek](https://github.com/mgmalek/efficient_cross_entropy) and [Liger-Kernel](https://github.com/linkedin/Liger-Kernel/blob/main/src/liger_kernel/ops/fused_linear_cross_entropy.py).
* [`Linear KL Divergence`](fla/modules/fused_kl_div.py): fused linear layer and KL divergence loss in a similar vein as CE loss.

### Generation

Upon successfully pretraining a model, it becomes accessible for generating text using the 🤗 text generation APIs.
In the following, we give a generation example:
```py
>>> import fla
>>> from transformers import AutoModelForCausalLM, AutoTokenizer
>>> name = 'fla-hub/gla-1.3B-100B'
>>> tokenizer = AutoTokenizer.from_pretrained(name)
>>> model = AutoModelForCausalLM.from_pretrained(name).cuda()
>>> input_prompt = "Power goes with permanence. Impermanence is impotence. And rotation is castration."
>>> input_ids = tokenizer(input_prompt, return_tensors="pt").input_ids.cuda()
>>> outputs = model.generate(input_ids, max_length=64)
>>> tokenizer.batch_decode(outputs, skip_special_tokens=True)[0]
```

We also provide a simple script [here](benchmarks/benchmark_generation.py) for benchmarking the generation speed.
Simply run it by:
```sh
$ python -m benchmarks.benchmark_generation \
  --path 'fla-hub/gla-1.3B-100B' \
  --repetition_penalty 2. \
  --prompt="Hello everyone, I'm Songlin Yang"

Prompt:
Hello everyone, I'm Songlin Yang
Generated:
Hello everyone, I'm Songlin Yang.
I am a 20 year old girl from China who is currently studying in the United States of America for my Master degree and also working as an English teacher at school here on campus since last summer (1st semester). My main goal to be able do well with this course so that we can have

Prompt length: 10, generation length: 64
Total prompt processing + decoding time: 4593ms
```

All of the pretrained models currently available can be found in [`fla-hub`](https://huggingface.co/fla-hub).
```py
>>> from huggingface_hub import list_models
>>> for model in list_models(author='fla-hub'): print(model.id)
```

### Hybrid Models

`fla` provides a flexible method to incorporate standard attention layers into existing linear attention models.
This is easily achieved by specifying the `attn` argument in the model configuration.

For example, to create a 2-layer Samba model with interleaved Mamba and local attention layers, using a sliding window size of 2048:

```py
>>> from fla.models import SambaConfig
>>> from transformers import AutoModelForCausalLM
>>> config = SambaConfig(num_hidden_layers=2)
>>> config.attn = {
  'layers': [1],
  'num_heads': 18,
  'num_kv_heads': 18,
  'window_size': 2048
}
>>> config
SambaConfig {
  "attn": {
    "layers": [
      1
    ],
    "num_heads": 18,
    "num_kv_heads": 18,
    "window_size": 2048
  },
  "bos_token_id": 1,
  "conv_kernel": 4,

During inference, you **DO NOT** need to revise anything for generation!
The model will produce output as-is, without any need for additional configurations or modifications.

## Evaluations

The [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness) library allows you to easily perform (zero-shot) model evaluations.
Follow the steps below to use this library:

1. Install `lm_eval` following [their instructions](https://github.com/EleutherAI/lm-evaluation-harness/blob/main/README.md).

2. Run evaluation with:
```sh
$ PATH='fla-hub/gla-1.3B-100B'
$ python -m evals.harness --model hf \
    --model_args pretrained=$PATH,dtype=bfloat16 \
    --tasks wikitext,lambada_openai,piqa,hellaswag,winogrande,arc_easy,arc_challenge,boolq,sciq,copa,openbookqa \
    --batch_size 64 \
    --num_fewshot 0 \
    --device cuda \
    --show_config  
```

We've made `fla` compatible with hf-style evaluations, you can call [evals.harness](evals/harness.py) to finish the evaluations.
Running the command above will provide the task results reported in the GLA paper.

3. Multi-GPU Evaluation with Hugging Face accelerate 🚀

To perform data-parallel evaluation (where each GPU loads a separate full copy of the model), we leverage the accelerate launcher as follows:
```sh
$ PATH='fla-hub/gla-1.3B-100B'
$ accelerate launch -m evals.harness --model hf \
    --model_args pretrained=$PATH,dtype=bfloat16 \
    --tasks wikitext,lambada_openai,piqa,hellaswag,winogrande,arc_easy,arc_challenge,boolq,sciq,copa,openbookqa \
    --batch_size 64 \
    --num_fewshot 0 \
    --device cuda \
    --show_config  
```

If a GPU can't load a full copy of the model, please refer to [this link](https://github.com/EleutherAI/lm-evaluation-harness?tab=readme-ov-file#multi-gpu-evaluation-with-hugging-face-accelerate) for FSDP settings.

> [!Tip]
> If you are using `lm-evaluation-harness` as an external library and can't find (almost) any tasks available, before calling `lm_eval.evaluate()` or `lm_eval.simple_evaluate()`, simply run the following to load the library's stock tasks!
```py
>>> from lm_eval.tasks import TaskManager; TaskManager().initialize_tasks()
```

## Benchmarks

We compared our Triton-based RetNet implementation with CUDA-based FlashAttention2, using a batch size of 8, 32 heads, and a head dimension of 128, across different sequence lengths.
These tests were conducted on a single A100 80GB GPU, as illustrated in the following graph
```py
# you might have to first install `fla` to enable its import via `pip install -e .`
$ python benchmark_retention.py
