FFCV: Fast Forward Computer Vision (and other ML workloads!)

Last update: Jan 03, 2023

Overview

Fast Forward Computer Vision: train models at a fraction of the cost with accelerated data loading!

[install] [quickstart] [features] [docs] [support slack] [homepage]
Maintainers: Guillaume Leclerc, Andrew Ilyas and Logan Engstrom

ffcv is a drop-in data loading system that dramatically increases data throughput in model training:

Train an ImageNet model on one GPU in 35 minutes (98¢/model on AWS)
Train a CIFAR-10 model on one GPU in 36 seconds (2¢/model on AWS)
Train a $YOUR_DATASET model $REALLY_FAST (for $WAY_LESS)

Keep your training algorithm the same, just replace the data loader! Look at these speedups:

ffcv also comes prepacked with fast, simple code for standard vision benchmarks:

Installation

conda create -y -n ffcv python=3.9 cupy pkg-config compilers libjpeg-turbo opencv pytorch torchvision cudatoolkit=11.3 numba -c pytorch -c conda-forge
conda activate ffcv
pip install ffcv

Troubleshooting note: if the above commands result in a package conflict error, try running conda config --env --set channel_priority flexible in the environment and rerunning the installation command.

(Make sure to replace xxxxxxx above with the hash of the commit used!)

Quickstart

Accelerate any learning system with ffcv. First, convert your dataset into ffcv format (ffcv converts both indexed PyTorch datasets and WebDatasets):

from ffcv.writer import DatasetWriter
from ffcv.fields import RGBImageField, IntField

# Your dataset (`torch.utils.data.Dataset`) of (image, label) pairs
my_dataset = make_my_dataset()
write_path = '/output/path/for/converted/ds.beton'

# Pass a type for each data field
writer = DatasetWriter(write_path, {
    # Tune options to optimize dataset size, throughput at train-time
    'image': RGBImageField(max_resolution=256, jpeg_quality=jpeg_quality),
    'label': IntField()
})

# Write dataset
writer.from_indexed_dataset(ds)

Then replace your old loader with the ffcv loader at train time (in PyTorch, no other changes required!):

from ffcv.loader import Loader, OrderOption
from ffcv.transforms import ToTensor, ToDevice, ToTorchImage, Cutout
from ffcv.fields.decoders import IntDecoder, RandomResizedCropRGBImageDecoder

# Random resized crop
decoder = RandomResizedCropRGBImageDecoder((224, 224))

# Data decoding and augmentation
image_pipeline = [decoder, Cutout(), ToTensor(), ToTorchImage(), ToDevice(0)]
label_pipeline = [IntDecoder(), ToTensor(), ToDevice(0)]

# Pipeline for each data field
pipelines = {
    'image': image_pipeline,
    'label': label_pipeline
}

# Replaces PyTorch data loader (`torch.utils.data.Dataloader`)
loader = Loader(write_path, batch_size=bs, num_workers=num_workers,
                order=OrderOption.RANDOM, pipelines=pipelines)

# rest of training / validation proceeds identically
for epoch in range(epochs):
    ...

Prepackaged Computer Vision Benchmarks

From gridding to benchmarking to fast research iteration, there are many reasons to want faster model training. Below we present premade codebases for training on ImageNet and CIFAR, including both (a) extensible codebases and (b) numerous premade training configurations.

ImageNet

We provide a self-contained script for training ImageNet fast. Above we plot the training time versus accuracy frontier, and the dataloading speeds, for 1-GPU ResNet-18 and 8-GPU ResNet-50 alongside a few baselines.

Link to Config	top_1	top_5	# Epochs	Time (mins)	Architecture	Setup
Link	0.784	0.941	88	77.2	ResNet-50	8 x A100
Link	0.780	0.937	56	49.4	ResNet-50	8 x A100
Link	0.772	0.932	40	35.6	ResNet-50	8 x A100
Link	0.766	0.927	32	28.7	ResNet-50	8 x A100
Link	0.756	0.921	24	21.7	ResNet-50	8 x A100
Link	0.738	0.908	16	14.9	ResNet-50	8 x A100
Link	0.724	0.903	88	187.3	ResNet-18	1 x A100
Link	0.713	0.899	56	119.4	ResNet-18	1 x A100
Link	0.706	0.894	40	85.5	ResNet-18	1 x A100
Link	0.700	0.889	32	68.9	ResNet-18	1 x A100
Link	0.688	0.881	24	51.6	ResNet-18	1 x A100
Link	0.669	0.868	16	35.0	ResNet-18	1 x A100

Train your own ImageNet models! You can use our training script and premade configurations to train any model seen on the above graphs.

CIFAR-10

We also include premade code for efficient training on CIFAR-10 in the examples/ directory, obtaining 93% top1 accuracy in 36 seconds on a single A100 GPU (without optimizations such as MixUp, Ghost BatchNorm, etc. which have the potential to raise the accuracy even further). You can find the training script here.

Features

Computer vision or not, FFCV can help make training faster in a variety of resource-constrained settings! Our performance guide has a more detailed account of the ways in which FFCV can adapt to different performance bottlenecks.

Plug-and-play with any existing training code: Rather than changing aspects of model training itself, FFCV focuses on removing data bottlenecks, which turn out to be a problem everywhere from neural network training to linear regression. This means that:
- FFCV can be introduced into any existing training code in just a few lines of code (e.g., just swapping out the data loader and optionally the augmentation pipeline);
- You don't have to change the model itself to make it faster (e.g., feel free to analyze models without CutMix, Dropout, momentum scheduling, etc.);
- FFCV can speed up a lot more beyond just neural network training---in fact, the more data-bottlenecked the application (e.g., linear regression, bulk inference, etc.), the faster FFCV will make it!
See our Getting started guide, Example walkthroughs, and Code examples to see how easy it is to get started!
Fast data processing without the pain: FFCV automatically handles data reading, pre-fetching, caching, and transfer between devices in an extremely efficiently way, so that users don't have to think about it.
Automatically fused-and-compiled data processing: By either using pre-written FFCV transformations or easily writing custom ones, users can take advantage of FFCV's compilation and pipelining abilities, which will automatically fuse and compile simple Python augmentations to machine code using Numba, and schedule them asynchronously to avoid loading delays.
Load data fast from RAM, SSD, or networked disk: FFCV exposes user-friendly options that can be adjusted based on the resources available. For example, if a dataset fits into memory, FFCV can cache it at the OS level and ensure that multiple concurrent processes all get fast data access. Otherwise, FFCV can use fast process-level caching and will optimize data loading to minimize the underlying number of disk reads. See The Bottleneck Doctor guide for more information.
Training multiple models per GPU: Thanks to fully asynchronous thread-based data loading, you can now interleave training multiple models on the same GPU efficiently, without any data-loading overhead. See this guide for more info.
Dedicated tools for image handling: All the features above work are equally applicable to all sorts of machine learning models, but FFCV also offers some vision-specific features, such as fast JPEG encoding and decoding, storing datasets as mixtures of raw and compressed images to trade off I/O overhead and compute overhead, etc. See the Working with images guide for more information.

Two or more crops for a single image

Hey! Thank you for the great work.

Is it possible to apply the same pipeline multiple times to the same image? From what I checked, this is currently not possible as it seems that the images are loaded and cropped within a single operation. Is there any way to go around this, loading the image only once and applying the augmentations pipelines multiple times?

Cifar10 example: very slow training speed on P100 GPU

Hello, as the title suggested, I run the cifar example code on a tesla-p100 gpu, but got a very slow training speed (784.29492) compared to the official stated one (36 s). Anything wrong in my setting? I don't think the p100 gpu is 20x slower than a100.

Below is the command line output (directly copy & paste and don't format it, sorry for that)

Git tag for v0.0.3

I see that there's a release tagged for v0.0.3rc1, but no tag for release v0.0.3 which is currently that latest release on pypi. Would it be possible to get a git tag for v0.0.3?

Having git tags for releases makes it a lot easier for others to package ffcv, eg in Nixpkgs.

$Tried allocating 144000000 but page size is {self.page_size}$

Tried allocating 144000000 but page size is {self.page_size}

Hi,

I am trying to convert my dataset into ffcv format. There are 3 inputs, img, ldx and, ldy. img has size (2, 600, 600), ldx has size(100,1,600,600) and, ldy has same size as ldy. Output has size (100,600,600) and all the inputs and outputs are float32. Witer works fine but writer.from_indexed_dataset(train_dataset) throws error:

"Tried allocating 144000000 but page size is {self.page_size}".

from dataset import dataset

num=20
train_dataset = dataset(num, is_train=True)

write_path = '/ffcv_test/d.beton'

for img, ldx, ldy, output in train_dataset:

How to perform identical transformation on images and targets in dense prediction tasks?

In dense prediction (or Pix2Pix) tasks such as segmentation, depth estimation etc, we often need to perform the same transformation on images and targets. e.g. Either both the image and the corresponding target should be horizontally flipped, or neither of them.

How do I achieve that with FFCV?

FFCV Imagenet Image Quality vs. Native Imagenet Image Quality
Hello! I see that FFCV offers alot of options for the quality of the dataset - e.g. in the imagenet example:

# - 50% JPEG encoded, 90% raw pixel values # - quality=90 JPEGs ./write_dataset.sh 500 0.50 90

One thing I'm curious is the effects of these quality options on the training results of the dataset, as I'm interested in reproducing Imagenet results but faster using FFCV. What would also be recommended settings to use if you would like to produce Native Imagenet Quality precisely (barring the crop size).

Is albumentations support useful?

HI, ffcv team! Thanks for your great work. ffcv is so exciting for me.

Do you plan to improve its interoperability with other libraries? In fact, I want to use more complicated augmentations on ffcv pipeline. So I tried to add a new Operation to wrap transforms of argumentation. These codes are below.

https://github.com/ar90n/ffcv/commit/f53d49dcdb7084f9a05dd99d49a4925814a6172b

It seems that they work correctly except for integrations with JIT-compiled codes. If are you interested in my work, I would like to contribute them to ffcv. What do you think?

can't pip install ffcv

Hi, I have an existing conda environment that I'm trying to add ffcv to. Oddly enough, if I create a new conda environment with ffcv in it (via the conda create line given in the docs), I can import ffcv just fine. However, if I want to add the ffcv dependancies to an existing conda environment, ffcv won't install. Here's my work flow.

(Note: I used pip instead of conda install because I get some

have an existing conda environment w/ python 3.8, cuda 10.2, torch 1.9, torchvision 0.10, numba
pip install open-cv, cupy, pkgconfig, compiler, pyturbojpeg (no libjpeg-turbo for pip available)
pip install ffcv

Then I get this exception:

Note: I used pip because when I tried to use conda for (cupy, pkg-config, compilers, open-cv, etc), I get this error:

Collecting package metadata (current_repodata.json): done
Solving environment: | 
The environment is inconsistent, please check the package plan carefully
The following packages are causing the inconsistency:

  - pytorch/linux-64::torchvision==0.10.0=py38_cu111
  - pytorch/linux-64::torchaudio==0.9.0=py38

Which after a long output of conflicts, it states this:

Your installed version is: 2.27

To get around this, I used pip, and didn't have these conflicts. But again, I can't install ffcv. Anybody have any idea what might be the issue?

Update:

I've also tried install opencv from source via https://docs.opencv.org/4.x/d7/d9f/tutorial_linux_install.html#tutorial_linux_install_quick_build_core, but still got the same exception above when trying to pip install ffcv

Update2:

I cloned the ffcv repo and ran python setup.py, and inspected the extension_kwargs var, and got this:

Error when using install ffcv using guidance command.
Hi, I am trying to install ffcv on my server. Here are the server settings.

Platform:amd-linux GPU: 1*RTX02080Ti

When I use the default code to create the environment, and set up the environment, I could not move data to gpu and an error occurred. Here is the error:

Torch not compiled with CUDA enabled

I have installed GPU driver on my server. Could you please tell me why this happens?

Unexpected pipeline behavior with NDArrayField

I don't think this is a bug, but as a new user it surprised me, perhaps its documented but if not perhaps should be. I define a dataset like so:

fshape = (1,31,32)
writer = DatasetWriter(write_path, {
    'data': NDArrayField(shape=fshape, dtype=np.dtype('float64')),
    'target': NDArrayField(shape=fshape, dtype=np.dtype('float64')),
    'vol': NDArrayField(shape=(1,fshape[-1]), dtype=np.dtype('float64')),
    'temp': NDArrayField(shape=(1,), dtype=np.dtype('float64')),

}, num_workers=64)

After writing the .beton file, I at first tried creating a loader using the same pipeline

float_pipeline = [NDArrayDecoder(), ToTensor()]

# Pipeline for each data field
pipelines = {
    'data': float_pipeline,
    'target': float_pipeline,
    'vol': float_pipeline,
    'temp': float_pipeline
}       

loader = Loader(ffcv_file, batch_size=64, num_workers=8,
                order=OrderOption.RANDOM, pipelines=pipelines)
data,target,vol,temp = next(iter(loader))

However, all of the variables have the shape of the smallest array, in this case temp (i.e. data is shape (Nbatch,1), where it should be (Nbatch,1,31,32)).

When I create separate pipelines for each variable which is a different size, then things come out correctly:

float_pipeline = [NDArrayDecoder(), ToTensor()]
vol_pipeline = [NDArrayDecoder(), ToTensor()]
T_pipeline = [NDArrayDecoder(), ToTensor()]

# Pipeline for each data field
pipelines = {
    'data': float_pipeline,
    'target': float_pipeline,
    'vol': vol_pipeline,
    'temp': T_pipeline
}

Unable to reproduce the results using the official training script

Hello,

Unfortunately I have been unable to reproduce reported results despite a lot of efforts.

Installation

conda create -y -n ffcv python=3.9 cupy pkg-config compilers libjpeg-turbo opencv pytorch torchvision cudatoolkit=11.3 numba -c pytorch -c conda-forge

As PyTorch 1.13 has been released and it only supports CUDA 11.6 and 11.7, the above installed the CPU version of PyTorch 1.13. Thus I had to install again PyTorch 1.12.1 for compatibility with CUDA 11.3:

conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=11.3 -c pytorch

And installation of dependencies:

conda activate ffcv
pip install torchmetrics

Create dataset

git clone https://github.com/libffcv/ffcv-imagenet.git
cd ffcv-imagenet
export IMAGENET_DIR=$HOME/data/imagenet
export WRITE_DIR=$HOME/data/imagenet_ffcv/jpg50
bash write_imagenet.sh 500 0.50 90

/home/.conda/envs/ffcv/lib/python3.9/site-packages/torchmetrics/utilities/prints.py:36: UserWarning: Torchmetrics v0.9 introduced a new argument class property called 
`full_state_update` that has
                not been set for this class (MeanScalarMetric). The property determines if `update` by
                default needs access to the full metric state. If this is not the case, significant speedups can be
                achieved and we recommend setting this to `False`.
                We provide an checking function
                `from torchmetrics.utilities import check_forward_full_state_property`
                that can be used to check if the `full_state_update=True` (old and potential slower behaviour,
                default for now) or if `full_state_update=False` can be used safely.

As you can see, epoch 0 already took 28 minutes to complete (the subsequent epochs took more than 6 minutes but this is still too high). I checked GPU utilization using nvidia-smi: all GPUs were used (and under-used, obviously):

My server has 8 GPU Nvidia A100 (SXM4 80 Go) and 512 GB of RAM, which is comparable to what was used in your experiments.

What should I check to see what went wrong? Could you please try reproducing the above on your side? I guess this would take only a few minutes (the write_imagenet step takes a lot of time but you already have the files so this step can be skipped).

Thank you very much in advance for your response!

Merging two FFCV .beton datasets

Hi

Let's say we have two datasets written to two FCCV dataset files say dataset1.beton and dataset2.beton. Assume both these datasets have the exact same image and label format and are written using the same method. Is it possible to take these two .beton dataset files and merge them into a single merged-dataset.beton FFCV dataset file?

This will be very useful when we want to continuously increase the size of the training datasets through continuous data collection.

Thanks!
