FinetuningScheduler explicit loss animation

FinetuningScheduler is simple to use yet powerful, offering a number of features that facilitate model research and exploration:

  • easy specification of flexible fine-tuning schedules with explicit or regex-based parameter selection
    • implicit schedules for initial/naive model exploration
    • explicit schedules for performance tuning, fine-grained behavioral experimentation and computational efficiency
  • automatic restoration of best per-phase checkpoints driven by iterative application of early-stopping criteria to each fine-tuning phase
  • composition of early-stopping and manually-set epoch-driven fine-tuning phase transitions

Setup

Step 0: Install from PyPI

pip install finetuning-scheduler
Additional installation options

Install Optional Packages

To install additional packages required for examples:

pip install finetuning-scheduler['examples']

or to include packages for examples, development and testing:

pip install finetuning-scheduler['all']

Source Installation Examples

To install from (editable) source (includes docs as well):

git clone https://github.com/speediedan/finetuning-scheduler.git
cd finetuning-scheduler
python -m pip install -e ".[all]" -r requirements/docs.txt

Install a specific FTS version from source using the standalone pytorch-lighting package:

export FTS_VERSION=2.0.0
export PACKAGE_NAME=pytorch
git clone -b v${FTS_VERSION} https://github.com/speediedan/finetuning-scheduler
cd finetuning-scheduler
python -m pip install -e ".[all]" -r requirements/docs.txt

Latest Docker Image

Note, publishing of new finetuning-scheduler version-specific docker images was paused after the 2.0.2 patch release. If new version-specific images are required, please raise an issue.

Docker Image Version (tag latest semver)

Step 1: Import the FinetuningScheduler callback and start fine-tuning!

import lightning as L
from finetuning_scheduler import FinetuningScheduler

trainer = L.Trainer(callbacks=[FinetuningScheduler()])

Get started by following the Fine-Tuning Scheduler introduction which includes a CLI-based example or by following the notebook-based Fine-Tuning Scheduler tutorial.

Installation Using the Standalone pytorch-lightning Package

applicable to versions >= 2.0.0

Now that the core Lightning package is lightning rather than pytorch-lightning, Fine-Tuning Scheduler (FTS) by default depends upon the lightning package rather than the standalone pytorch-lightning. If you would like to continue to use FTS with the standalone pytorch-lightning package instead, you can still do so as follows:

Install a given FTS release (for example v2.0.0) using standalone pytorch-lightning:

export FTS_VERSION=2.0.0
export PACKAGE_NAME=pytorch
wget https://github.com/speediedan/finetuning-scheduler/releases/download/v${FTS_VERSION}/finetuning-scheduler-${FTS_VERSION}.tar.gz
pip install finetuning-scheduler-${FTS_VERSION}.tar.gz

Continuous Integration

Fine-Tuning Scheduler is rigorously tested across multiple CPUs, GPUs and against major Python and PyTorch versions. Each Fine-Tuning Scheduler minor release (major.minor.patch) is paired with a Lightning minor release (e.g. Fine-Tuning Scheduler 2.0 depends upon Lightning 2.0).

To ensure maximum stability, the latest Lightning patch release fully tested with Fine-Tuning Scheduler is set as a maximum dependency in Fine-Tuning Scheduler's requirements.txt (e.g. <= 1.7.1). If you'd like to test a specific Lightning patch version greater than that currently in Fine-Tuning Scheduler's requirements.txt, it will likely work but you should install Fine-Tuning Scheduler from source and update the requirements.txt as desired.
