FM Training Estimator

Estimators for Large Language Model Training.

Estimate resource consumption - memory, tokens, time etc for training and fine-tuning jobs using an hybrid of theory and learned regression models.

Feature Matrix and Roadmap

Technique	Support
Full (1 gpu)	✔️

Time

Full learned approach. Coverage based on availability of training data.

Memory

Hybrid theory + learned. Coverage of learned approach is subject to availability of training data.

Tokens

Fully theory. Simulation based models available.

Technique	Explanation	Availability
TE0	Simulation based - slow but accurate	✔️
TE1	Statistical	Planned
TE2	Approximate - fast, light, reasonable accurate	Coming soon

Usage

You can use the library fm_training_estimator as a Python package by installing it via pip, see installation, build a regression model and using the library. If you'd like to construct the estimator service with a Web UI via FastAPI or build a docker image, clone the repository in your local machine before following the instructions in those sections.

Within your working directory, it is recommended to create a virtual environment to ensure no conflicts in dependencies.

python -m venv .venv
source .venv/bin/activate

Install

pip install fm_training_estimator

Build a regression model for learned prediction method

Now, prepare data in the expected format for lookup and regression. Some example data csv files are here. Save your data file into ./workdir/data.csv.

mkdir workdir
mv <data file> ./workdir/data.csv

Now, build a regression model using this data, using the provided make target:

from fm_training_estimator.regressor.xgboost.train import train 
train("./workdir/data.csv", "./workdir/model.json", ["tokens_per_second","memory","memory_act"])

This will create a model called ./workdir/model.json which you can then use to estimate the resource consumption.

You can now run the estimator library, see below.

Use the library to get estimates

Example code:

# Standard
import os

# First Party
from fm_training_estimator.config.arguments import (
    DataArguments,
    EstimateInput,
    EstimatorMetadata,
    FMArguments,
    HFTrainingArguments,
    InfraArguments,
    JobConfig,
)
from fm_training_estimator.sdk import (
    estimate_cost,
    estimate_memory,
    estimate_time,
    estimate_tokens,
)

workdir_path = os.path.join(os.path.abspath(os.curdir), "workdir")

model_path = os.path.join(workdir_path, "model.json")
lookup_data_path = os.path.join(workdir_path, "data.csv")

estimator_metadata = EstimatorMetadata(base_data_path=lookup_data_path)

fm = FMArguments(
    base_model_path="ibm-granite/granite-7b-base",
    torch_dtype="bfloat16",
    block_size=1024,
)
hf_training = HFTrainingArguments(
    per_device_train_batch_size=1, gradient_checkpointing=False
)
data = DataArguments(dataset="imdb", te_approach=0)
infra = InfraArguments(numGpusPerPod=1)
job_conf = JobConfig(hf_training, fm, data, infra)
est_input = EstimateInput(estimator_metadata=estimator_metadata, job_configs=[job_conf])

print("Estimating Memory:....")

print("With only theory: ", estimate_memory(est_input))
print("With reg model: ", estimate_memory(est_input, model_path))

hf_training.fsdp = "full_shard"

print("Using fsdp full shard")
print("With only theory: ", estimate_memory(est_input))
print("With reg model: ", estimate_memory(est_input, model_path))


print("Estimating Time:....")
print("With only theory: ", estimate_time(est_input))
print("With reg model: ", estimate_time(est_input, model_path))

print("Estimating Tokens:....")
print("With only theory: ", estimate_tokens(est_input))
print("With reg model: ", estimate_tokens(est_input, model_path))

Make estimates via a Web UI

To do this, first prepare a txt file called model_whitelist.txt in the workdir/ with a list of model names, 1 per line. Note that these are the models on which you want to run the estimator to estimate their resource consumption. You can use the provided example and place it in your workdir. Modify this list as needed.

Now, run the ui:

make run-web-ui

This will start the UI on localhost:3000 port.

(The web ui has other options, not covered in this simple setup. If you want to skip the model whitelisting or change the port, directly run the UI as shown in the README in the ./fm_training_estimator/ui folder.)

Build a Docker Container Image

To build the estimator container image:

1. Make sure both model.json and data.csv files are present in the workdir folder.

2. Use this command to build and push the image:

make cbuild
make cpush # If you want to push to the container registry

3. Use this command to run the image:

docker run --rm -it -v "/path/to/input.json:/app/input.json" icr.io/ftplatform/fm_training_estimator:latest
