tried merging the checkpoints as described for single GPU python tools/merge20b.py --input_dir ./20B_checkpoints --output_dir ./20B_checkpoints_merged

However Im getting this error when generating RuntimeError: Error(s) in loading state_dict for EmbeddingPipe: size mismatch for word_embeddings.weight: copying a param with shape torch.Size([50432, 6144]) from checkpoint, the shape in current model is torch.Size([50304, 6144]).

How can I adjust to make the current model match size 50432? or is it the other way around?

Clean up neox configuration so config files can be used instead of a mishmash of files, command line args and enviroment variables.

Aim:

• All parameters can be set using passed json files
• No parameters are repeated
• Modify megatron's codebase as little as possible to make it easier to merge upstream megatron changes in the future.

Nice to haves:

• JSON schema files
• Single config documentation

Todo:

• [x] Convert all examples and configs to new configuration
• [ ] Create config documentation with all possible parameters
• [x] Separate configs into: model and system
• [x] Cast numbers to numbers in JSON (suggested by @StellaAthena)
• [x] Calculate batch size from other parms (micro_batch_per_gpu*GAS*n_gpus)

The modeling and configuration files are largely based on HF's gpt-j model. (I found gpt-j's architecture more similar to gpt-neox than gpt-neo, especially it uses rotary embedding)

Modifications to the original gpt-j modeling:

• Added post-attention layernorm as ln_2.
• Changed q_proj, k_proj, v_proj linear layers to a single qkv_proj that corresponds to gpt-neox's attention.query_key_value linear layer. And set bias=True.
• Combined gpt-neox's and HF gpt-j's rotatry embedding functions.
• Set bias=False for lm_head.
• Updated the computation in GPTNeoXBlock in correspondence to two residual computing ways in gpt-neox, which is controlled by a new config argument gpt_j_residual.

Modifications to the original gpt-j configuration:

• Set the default value of activation_function to gelu.
• Removed rotary_dim (so that its default value is None).
• Added a gpt_j_residual argument (default value is False) in correspondence to two residual computing ways in gpt-neox.

A conversion script:

• that reads config files and gpt-neox's output state dict files and outputs a pretrained HF pytorch GPTNeoX model.
• Note that weights are not loaded for two kinds of model parameters transformer.h.*.attn.bias and transformer.h.*.attn.masked_bias because they should keep their default values.

Things that I have checked with a 1B model, which is trained basically following the default XL.yml config:

• The above conversion script works correctly.
• The greedy-decoding outputs by gpt-neox's inference script and HF's generate() are identical.
• Intermediate outputs (e.g. hidden states) are almost identical when running from gpt-neox code and HF code. There are some small differences, which I think are caused by precision settings.

Things that are not included in this pull request:

• Tensorflow-related code.
• Conversion script that considers checkpoints trained with model parallel.
• Other model variants that might use a different type of, for example, rotary embeddings.
• Things that haven't come to my mind.

BTW, I haven't found a better place to put the new files so I simply created a directory huggingface under /tools.

A table that summarizes parameters (and their shapes) in 1) a GPT-NeoX checkpoint, 2) an HF GPTNeo model, 3) an HF GPTJ model, and 4) the HF GPTNeoX model in this pull request:

Looking deeper into the gpt-j residual implementation I found a delta in the way layernorm(s) are applied. I don't see the point in applying two separate layer norm modules to the hidden_states (x)

Compare the HF implementation. https://github.com/huggingface/transformers/blob/a94105f95fb66ee4129077c03e4e8a224f6a07fd/src/transformers/models/gptj/modeling_gptj.py#L279

Is there a reason for having two layernorms? Am I completally off?

Hi!

Thanks for contribution making this repo available :)

I tried to train the 13B model with micro batch size 1, model parallelism degree 8, but unable to get it to work. (always get OOM) The library advertises being able to scale up to 100B. What is required for this? I also tried deepspeed stage 3 with offload without using pipeline parallelism but that doesn't seem to work either. Please let me know what I'm missing. thanks!

This PR adds Tri Dao's Flash Attention as an optional backend for the global attention operation, enabled by setting the attention_config to [[["flash"], ...]. I've tested the changes in my own environment and consistently see a 2x boost for 4K sequence lengths in models ranging from 100M - 3B parameters.

Maybe relevant: @tridao @lucidrains

Pipeline parallelism and gradient checkpointing both work when you use them individually. However when you turn them both on you get a mysterious KeyError: 0 from somewhere deep in DeepSpeed.

Hi, I want train a 13B model with 4 nodes, each node have 8*A100 GPUs, but I don't know how to run the code on my cluster, can you show me an example? I just run it on a single node successful.

Restart the now reverted previous fix.

History:

• Old PR was merged, after which some (small?) differences in model output became apparent in discussion with @sdtblck
• Old PR was reverted
• This PR is opened to discuss the issue

Tests and validations so far:

Inference was tested on a trained neox checkpoint (model size ~4B, 60k steps trained). Random sampling is deactivated (no top_k, top_p, temperature).

1. test NOT using recompute, i.e. with cache values used in the text generation (interactive)

python deepy.py generate.py -d configs ... text_generation

(copy pasted from terminal) Context prompt >>> Once upon a time Generated Text: , the only way to get a job at any of the many colleges and universities in the United States of America was to have a high school diploma

=> the model is working => generated text seems far from random (though not a fairytale :-) )

2. test using recompute, i.e. with NO cache values used in the text generation (interactive)

python deepy.py generate.py -d configs ... text_generation

(copy pasted from terminal) Context prompt >>> Once upon a time Generated Text: , the only way to get a job at any of the many colleges and universities in the United States of America was to have a high school diploma

=> The generated text is exactly the same as above

Tests and validations that resulted in discussions.

The following line has been added to text_generation_utils.py to print logits.

=> Generated text still the same => Logits are different. This is the question at hand

Questions

• Why are logits different?
• Does the difference only occur for alibi? Is this a general issue if an issue at all?

Describe the bug When using an image based on the provided Dockerfile and running the quick start steps (download enron data, run deep.py), execution crashes before training begins.

To Reproduce Steps to reproduce the behavior:

1. Build an image using the provided Dockerfile
2. Run said image, mounting 8 RTX800 GPUs
3. Fetch enron data using the prepare_dataset.py script
4. Run ./deepy.py pretrain_gpt2.py -d configs small.yml local_configs.yml
5. The code crashes with a non-descript NCCL error in: /pytorch/torch/lib/c10d/ProcessGroupNCCL.cpp:825, unhandled system error, NCCL version 2.7.8

Expected behavior Training starts or a specific error is provided.

Proposed solution The NCCL error is typically a stand-in for a real issue that is not relayed back through multiprocessing. As a first step, it would be nice to know if this setup works out-of-the-box for others; in that case, it might be my resources or CUDA version.

Environment (please complete the following information):

• GPUs: 8 RTX8000 GPUs
• Configs: Ubuntu 20.04, Cuda 11.2

Additional context Add any other context about the problem here.

We will want to run experiments with a variety of configs and options. To enable this, we need two things:

• [ ] configs files that we can use to specify the settings for a particular run
• [ ] an experiment runner for managing and automatically executing several runs

Describe the bug In interactive mode prompt length more than one word causes to crash. When I type just one word it generates text though.

This PR fixes #750 . Upstream DeepSpeed saves checkpoints in a new layout which is incompatible with the old conversion script. This makes convert_to_hf.py work with upstream DeepSpeed, and leaves legacy_convert_to_hf.py for conversion from DeeperSpeed.

Draft for now because I need to test on a real model.

The tools/convert_to_hf.py script will need to be updated / a different version may need to be created for checkpoints saved with DeepSpeed. Checkpoints are no longer saved layer-by-layer, it seems, and now all weights are in several mp_rank_{MP_RANK}_model_states.pt files for each Model Parallel partition.

Describe the bug I get the following error upon trying to use predictor.predict(data) for AWS Sagemaker.

ModelError: An error occurred (ModelError) when calling the InvokeEndpoint operation: Received client error (400) from primary with message "{
  "code": 400,
  "type": "InternalServerException",
  "message": "Could not load model /.sagemaker/mms/models/EleutherAI__gpt-neox-20b with any of the following classes: (\u003cclass \u0027transformers.models.auto.modeling_auto.AutoModelForCausalLM\u0027\u003e, \u003cclass \u0027transformers.models.gpt_neox.modeling_gpt_neox.GPTNeoXForCausalLM\u0027\u003e)."
}

To Reproduce Steps to reproduce the behavior:

1. Create Dockerfile
2. Add the following into Dockerfile

FROM 763104351884.dkr.ecr.us-east-1.amazonaws.com/huggingface-pytorch-inference:1.10.2-transformers4.17.0-gpu-py38-cu113-ubuntu20.04
RUN pip install --upgrade 'transformers==4.25.1'
RUN pip install --upgrade 'torch==1.13.0'

3. Build the Dockerfile via command docker build -t gpt-neox . in the directory Dockerfille is in
4. Create a file named dockerize.sh
5. Add the following content into the file

%%sh

# Specify an algorithm name
algorithm_name=gpt-neox

account=$(aws sts get-caller-identity --query Account --output text)

# Get the region defined in the current configuration (default to us-west-2 if none defined)
region=$(aws configure get region)

fullname="${account}.dkr.ecr.${region}.amazonaws.com/${algorithm_name}:latest"

# If the repository doesn't exist in ECR, create it.

aws ecr describe-repositories --repository-names "${algorithm_name}" > /dev/null 2>&1
if [ $? -ne 0 ]
then
aws ecr create-repository --repository-name "${algorithm_name}" > /dev/null
fi

# Log into Docker
aws ecr get-login-password --region ${region}|docker login --username AWS --password-stdin ${fullname}

# Build the docker image locally with the image name and then push it to ECR
# with the full name.

docker build -t ${algorithm_name} .
docker tag ${algorithm_name} ${fullname}

docker push ${fullname}

7. Run command docker login (you need docker cli)
8. Execute the shell script file (you need aws cli)
9. Open Jupyter Notebook
10. Add the following to Jupyter Notebook

%pip install sagemaker
%pip install boto3

from sagemaker.huggingface import HuggingFaceModel
import boto3

client=boto3.client('sts')
account=client.get_caller_identity()['Account']

my_session=boto3.session.Session()
region=my_session.region_name

algorithm_name="gpt-neox"
tag="latest"
ecr_image='{}.dkr.ecr.{}.amazonaws.com/{}:{}'.format(account, region, algorithm_name, tag)

role = 'SageMaker'

hub = {
    'HF_MODEL_ID':'EleutherAI/gpt-neox-20b',
    'HF_TASK':'text-generation'
}

huggingface_model = HuggingFaceModel(
    image_uri=ecr_image,
    env=hub,
    role=role,
#     transformers_version="4.17", these are not needed anymore
#     pytorch_version="1.10",
#     py_version="py38",
)

predictor = huggingface_model.deploy(
    initial_instance_count=1,
    instance_type="ml.m5.xlarge"
)

12. Run this final command in Jupyter Notebook once predictor is done.

predictor.predict({
    "inputs": "The weather is"
})

13. See error

Expected behavior I expect to see a generated query from the input using the 20 billion parameters pretrained EleutherAI model.

Proposed solution I suspect I could fix this issue if I all together ditched the huggingface Sagemaker library. Also, the model hasn't been updated for the last 8 months, so I'm not sure if it is due to that.

Environment (please complete the following information):

• GPUs: none
• Configs: unsure

Additional context I have tried the other versions of GPT-Neo's like 125M and 2.7B and those have worked perfectly. The reason that I need to extend the Docker container for AWS is to not get another error which is apparently an issue with the latest version of transformers (4.17?) on the default docker is not up to date enough.

Describe the bug

Using DeeperSpeed-trained model checkpoints (git+https://github.com/EleutherAI/DeeperSpe[email protected]#egg=deepspeed ),

loading them raises an error when trying to use deepspeed_main with the upstream DeepSpeed.

To Reproduce Steps to reproduce the behavior:

Train a model from main branch using DeeperSpeed (or download model ckpt from s-eai-neox/pythia/1.3B/global_step71500)

Try to load this checkpoint using the deepspeed_main branch and upstream Deepspeed (for either training or evaluation), gives the following error:

Traceback (most recent call last):
  File "/fsx/hailey/deepspeed-main-neox/gpt-neox/evaluate.py", line 76, in <module>

    model, _, _ = setup_model_and_optimizer(
  File "/fsx/hailey/deepspeed-main-neox/gpt-neox/megatron/training.py", line 437, in setup_model_and_optimizer
    neox_args.iteration = load_checkpoint(
  File "/fsx/hailey/deepspeed-main-neox/gpt-neox/megatron/checkpointing.py", line 235, in load_checkpoint
    checkpoint_name, state_dict = model.load_checkpoint(
  File "/fsx/shiv/torchtest/lib/python3.8/site-packages/deepspeed/runtime/engine.py", line 2647, in load_checkpoint
    load_path, client_states = self._load_checkpoint(load_dir,
  File "/fsx/shiv/torchtest/lib/python3.8/site-packages/deepspeed/runtime/engine.py", line 2713, in _load_checkpoint
    self.load_module_state_dict(state_dict=checkpoint['module'],
  File "/fsx/shiv/torchtest/lib/python3.8/site-packages/deepspeed/runtime/engine.py", line 2507, in load_module_state_dict
    self.module.load_state_dict(state_dict, # TODO
  File "/fsx/shiv/torchtest/lib/python3.8/site-packages/torch/nn/modules/module.py", line 1620, in load_state_dict
    raise TypeError("Expected state_dict to be dict-like, got {}.".format(type(state_dict)))
TypeError: Expected state_dict to be dict-like, got <class 'NoneType'>.

This gives the above traceback and checkpoint loading fails.

Expected behavior The checkpoints should be loadable by either Deepspeed version, ideally.

Proposed solution This could be an issue with Deepspeed checkpoint formats changing over the course of 4 versions--not sure yet.

Additional context Relevant to merging #663 since we have checkpoints we want to use trained in DeeperSpeed.
