EasyDeL 0.0.55

An open-source library to make training faster and more optimized in Jax/Flax

EasyDeL 🔮

EasyDeL, an open-source library, is specifically designed to enhance and streamline the training process of machine learning models. It focuses primarily on Jax/Flax and aims to provide convenient and effective solutions for training Flax/Jax Models on TPU/GPU for both Serving and Training purposes. Additionally, EasyDeL will support mojo and will be rewritten for mojo as well.

Some of the key features provided by EasyDeL include:

• Serving and API Engines for Using and serving LLMs in JAX as efficiently as possible.
• Support for 8, 6, and 4 BIT inference and training in JAX
• A wide range of models in Jax is supported which have never been implemented before such as Falcon, Qwen2, Phi2, Mixtral, and MPT ...
• Integration of flashAttention in JAX for GPUs and TPUs
• Automatic serving of LLMs with mid and high-level APIs in both JAX and PyTorch
• LLM Trainer and fine-tuner in JAX
• Video CLM Trainer and Fine-tunerFalcon, Qwen2, Phi2, Mixtral, and MPT ...
• RLHF (Reinforcement Learning from Human Feedback) in Jax (Beta Stage)
• DPOTrainer(Supported) and SFTTrainer(Developing Stage)
• Various other features to enhance the training process and optimize performance.
• LoRA: Low-Rank Adaptation of Large Language Models
• RingAttention, Flash Attention, BlockWise FFN, and Efficient Attention are supported for more than 90 % of models (FJFormer Backbone).
• Serving and API Engines for Using and serving LLMs in JAX as efficient as possible.
• Automatic Converting Models from JAX-EasyDeL to PyTorch-HF and reverse

[!NOTE] In case of using EasyDel on Kaggle TPUs you need to upgrade tensorflow version too.

[!NOTE] EasyDel Will only support JAX>=0.4.22 Due to miss computations being happened in older version and also not bein able to run Flash Attention and Splash Attention (Splash Attention is still under Process)

[!NOTE] These features collectively aim to simplify and accelerate the training of machine learning models, making it more efficient and accessible for developers working with Jax/Flax.

Documentation 💫

[!IMPORTANT] Documents and Examples are ready at Here Please have that in mind that EasyDel is in the loop of fast-development so we might have API changes

Serving

you can read docs or examples to see how JAXServer works but let me show you how you can simply host and serve any model that supported by EasyDeL fo this example ill just use gemma-7-it by google but you can use any model as you wish.

python -m examples.jax_serve_example \
  --prompter_type="gemma" \ 
  --share_gradio=True \ 
  --sharding_axis_dims=1,1,1,-1 \
  --attn_mechanism="normal" \
  --scan_ring_attention=True \
  --max_sequence_length=8192 \ 
  --max_new_tokens_ratio=25 \
  --max_compile_tokens=256 \ 
  --block_k=128 \
  --block_q=128 \
  --pretrained_model_name_or_path="google/gemma-7b-it" \
  --dtype="bf16"

[!NOTE] you can use EasyServe which is a Serve API Engine for production purpose sice that's more stable provide versioned API and efficient.

RLHF(Reinforcement Learning From Human Feedback)

RLHF or Reinforcement Learning From Human Feedback is Available At the moment, but it's still under heavy development , because I don't have enough experience with Reinforcement Learning at the moment so its still in beta version but it's works and ill soon release a Tutorial For that

FineTuning

with using EasyDel FineTuning LLM (CausalLanguageModels) are easy as much as possible with using Jax and Flax and having the benefit of TPUs for the best speed here's a simple code to use in order to finetune your own Model

Days Has Been Passed and now using easydel in Jax is way more similar to HF/PyTorch Style now it's time to finetune our model

)

output = trainer.train(flax.core.FrozenDict({"params": params}))
print(f"Hey ! , here's where your model saved {output.checkpoint_path}")

[!TIP] you can then convert it to pytorch for better use I don't recommend jax/flax for hosting models since pytorch is better option for gpus

LLMServe

To use EasyDeL in your project, you will need to import the library in your Python script and use its various functions and classes. Here is an example of how to import EasyDeL and use its Model class:

from EasyDel.modules import AutoEasyDelModelForCausalLM
from EasyDel.serve import JAXServer
from transformers import AutoTokenizer
import jax

model_huggingface_repo_id = "meta-llama/Llama.md-2-7b-chat-hf"

tokenizer = AutoTokenizer.from_pretrained(model_huggingface_repo_id, trust_remote_code=True)
model, params = AutoEasyDelModelForCausalLM.from_pretrained(
    model_huggingface_repo_id,
    jax.devices("cpu")[0],
    jax.numpy.float16,
    jax.numpy.float16,
    jax.lax.Precision("fastest"),
    (1, 1, 1, -1),
    device_map="auto"
)

server = JAXServer.from_parameters(
    model=model,
    config_model=model.config,
    tokenizer=tokenizer,
    params=model.params,
    add_params_field=True
)

response_printed = 0
for response, tokens_used in server.process(
        "String To The Model", stream=True
):
    print(response[response_printed:], end="")
    response_printed = len(response)

DPO Fine-tuning

DPOTrainer is the new Trainer in EasyDeL, so you might have except some bugs in process but as far as i have tested everything works just fine, and you can consider it the first DPO Trainer in JAX/Flax let have an example and see how you can fine-tune your own model with DPOTrainer

[!TIP] In case that you want a better script to learn about DPOTrainer you can see examples at here which contain DPO Tuning a Mixtral model with Intel DPO dataset.

now you have trained your first model Using DPOTrainer in JAX with EasyDeL.

[!TIP] The API of EasyDeL DPO Trainer is similar to DPO Trainer in TRL from HuggingFace so that means you have freedom and have access to a hackable and changeable code.

EasyDelState

EasyDelState is new and cool feature in EasyDeL and have a lot of options like storing Model Parameters, Optimizer State, Model Config, Model Type, Optimizer and Scheduler Configs

Let see and examples of using EasyDelState

Fine-tuning

Fine-tuning from a previous State or a new state

from EasyDel import (
    AutoEasyDelConfig,
    EasyDelState
)
from transformers import AutoTokenizer
from jax import numpy as jnp, lax
import jax

huggingface_model_repo_id = "REPO_ID"
checkpoint_name = "CKPT_NAME"

state = EasyDelState.from_pretrained(
    pretrained_model_name_or_path=huggingface_model_repo_id,
    filename=checkpoint_name,
    optimizer="adamw",
    scheduler="none",
    tx_init=None,
    device=jax.devices('cpu')[0],  # Offload Device
    dtype=jnp.bfloat16,
    param_dtype=jnp.bfloat16,
    precision=lax.Precision("fastest"),
    sharding_axis_dims=(1, 1, 1, -1),
    # the way to shard model across gpu,cpu or TPUs using sharding array (1, 1, 1, -1)
    # everything training will be in sequence and model parallel automatic and share data between devices
    sharding_axis_names=("dp", "fsdp", "tp", "sp"),
    query_partition_spec=jax.sharding.PartitionSpec(("dp", "fsdp"), "sp", "tp", None),
    key_partition_spec=jax.sharding.PartitionSpec(("dp", "fsdp"), "sp", "tp", None),
    value_partition_spec=jax.sharding.PartitionSpec(("dp", "fsdp"), "sp", "tp", None),
    bias_partition_spec=jax.sharding.PartitionSpec(("dp", "fsdp"), None, None, None),
    attention_partition_spec=jax.sharding.PartitionSpec(("dp", "fsdp"), "sp", "tp", None),
    use_shard_map=False,
    input_shape=(1, 1),
    backend=None,
    init_optimizer_state=False,
    free_optimizer_state=True,
    verbose=True,
    state_shard_fns=None,
)

config = AutoEasyDelConfig.from_pretrained(
    huggingface_model_repo_id
)

config.use_pjit_attention_force = False

tokenizer = AutoTokenizer.from_pretrained(
    huggingface_model_repo_id,
    trust_remote_code=True
)

max_length = config.max_position_embeddings

configs_to_initialize_model_class = {
    'config': config,
    'dtype': jnp.bfloat16,
    'param_dtype': jnp.bfloat16,
    'input_shape': (8, 8)
}

EasyDelState also has .load_state() and .save_state() with some other usable options like .free_opt_state() which free optimizer state or .shard_params() which shard parameters you can read docs in order to find out more about these options.

Converting to Huggingface and Pytorch

Let see how you can convert a EasyDelMistral Model to Huggingface Pytorch Mistral Model from a trained State

from transformers import MistralForCausalLM
from EasyDel import (
    AutoEasyDelConfig,
    EasyDelState,
    easystate_to_huggingface_model
)
import jax

huggingface_model_repo_id = "REPO_ID"

config = AutoEasyDelConfig.from_pretrained(
    huggingface_model_repo_id
)
with jax.default_device(jax.devices("cpu")[0]):
    model = easystate_to_huggingface_model(
        state=EasyDelState.load_state(
            "PATH_TO_CKPT"
        ),  # You can Pass EasyDelState here
        base_huggingface_module=MistralForCausalLM,
        config=config
    )

model = model.half()  # it's a huggingface model now

Other Use Cases

EasyDelState have a general use you can use it everywhere in easydel for example for a stand-alone model , serve, fine-tuning and many other features, it's up to you to test how creative you are 😇.

Flash Attention and Splash Attention Are Here 🥵

here's a simple example about how can you use Flash Attention in EasyDeL

# Config is built in config for every model (EasyDelPretrainedConfig)
config.add_basic_configurations(
    attn_mechanism="flash",  # flash , normal or splash (not fully supported yet on GPU,TPU) 
    block_b=1,
    block_q=512,
    block_k=512,
    block_k_major=512
)

Flash Attention works on TPU with ease but for gpu there are still some improvements in process.

EasyDeLXRapTure for layer tuning and LoRA

in case of using LoRA and applying that on the EasyDeL models there are some other things that you might need to config on your own but a lot of things being handled by EasyDeL so let just jump into an example for LoRA fine-tuning section and use EasyDeLXRapTure in for mistral models with flash attention example
