Figure 1: An Example for FedAvg. You can create a scenario using generate_X.py
and run an algorithm using main.py
, clientX.py
, and serverX.py
.
We expose this user-friendly algorithm library (with an integrated evaluation platform) for beginners who intend to start federated learning (FL) study.
-
34 traditional FL (tFL) or personalized FL (pFL) algorithms, 3 scenarios, and 14 datasets.
-
Some experimental results are avalible here.
-
Refer to this guide to learn how to use it.
-
This library can simulate scenarios using the 4-layer CNN on Cifar100 for 500 clients on one NVIDIA GeForce RTX 3090 GPU card with only 5.08GB GPU memory cost.
-
To simultaneously support statistical and model heterogeneity, please refer to our extended project Heterogeneous Federated Learning (HtFL).
-
As we strive to meet diverse user demands, frequent updates to the project may alter default settings and scenario creation codes, affecting experimental results.
The origin of the statistical heterogeneity phenomenon is the personalization of users, who generate the non-IID (not Independent and Identically Distributed) and unbalanced data. With statistical heterogeneity existing in the FL scenario, a myriad of approaches have been proposed to crack this hard nut. In contrast, the personalized FL (pFL) may take the advantage of the statistically heterogeneious data to learn the personalized model for each user.
Thanks to @Stonesjtu, this library can also record the GPU memory usage for the model. By using the package opacus, we introduce DP (differential privacy) into this library (please refer to ./system/flcore/clients/clientavg.py
for example). We also introduce the DLG (Deep Leakage from Gradients) attack and PSNR (Peak Signal-to-Noise Ratio) metric to evaluate the privacy-preserving ability of tFL/pFL algorithms (please refer to ./system/flcore/servers/serveravg.py
for example). Now we can train on some clients and evaluate on other new clients by setting args.num_new_clients
in ./system/main.py
. Note that not all the tFL/pFL algorithms support this feature.

For the label skew scenario, we introduce 8 famous datasets: MNIST, Fashion-MNIST, Cifar10, Cifar100, AG_News, Sogou_News, and Tiny-ImageNet (fetch raw data from this site), they can be easy split into IID and non-IID version. Since some codes for generating datasets such as splitting are the same for all datasets, we move these codes into ./dataset/utils/dataset_utils.py
. In non-IID scenario, 2 situations exist. The first one is the pathological non-IID scenario, the second one is practical non-IID scenario. In the pathological non-IID scenario, for example, the data on each client only contains the specific number of labels (maybe only 2 labels), though the data on all clients contains 10 labels such as MNIST dataset. In the practical non-IID scenario, Dirichlet distribution is utilized (please refer to this paper for details). We can input balance
for the iid scenario, where the data are uniformly distributed.
For the feature shift scenario, we use 3 datasets that are widely used in Domain Adaptation: AmazonReview (fetch raw data from this site), Digit5 (fetch raw data from this site), and DomainNet.
For the real-world (or IoT) scenario, we also introduce 3 naturally separated datasets: Omniglot (20 clients, 50 labels), HAR (Human Activity Recognition) (30 clients, 6 labels), PAMAP2 (9 clients, 12 labels). For the details of datasets and FL algorithms in IoT, please refer to my FL-IoT repo.
If you need another data set, just write another code to download it and then using the utils.

Install CUDA.
Install conda and activate conda.
conda env create -f env_cuda_latest.yaml # You may need to downgrade the torch using pip to match CUDA version
-
Create proper environments (see Environments).
-
Download this project to an appropriate location using git.
git clone https://github.com/TsingZ0/PFLlib.git
-
Build evaluation scenarios (see Datasets and scenarios (updating)).
-
Run evaluation:
cd ./system python main.py -data mnist -m cnn -algo FedAvg -gr 2000 -did 0 # using the MNIST dataset, the FedAvg algorithm, and the 4-layer CNN model
Or you can uncomment the lines you need in
./system/examples.sh
and run:cd ./system sh examples.sh
Note: The hyper-parameters have not been tuned for the algorithms. The values in ./system/examples.sh
are just examples. You need to tune the hyper-parameters by yourself.
If you need to simulate FL under practical situations, which includes client dropout, slow trainers, slow senders, and network TTL, you can set the following parameters to realize it.
-cdr
: The dropout rate for total clients. The selected clients will randomly drop at each training round.-tsr
and-ssr
: The rates for slow trainers and slow senders among all clients. Once a client was selected as "slow trainers", for example, it will always train slower than the original one. So does "slow senders".-tth
: The threshold for network TTL (ms).
It is easy to add new algorithms and datasets to this library.
-
To add a new dataset into this library, all you need to do is writing the download code and using the utils which is similar to
./dataset/generate_mnist.py
(you can also consider it as the template). -
To add a new algorithm, you can utilize the class Server and class Client, which are wrote in
./system/flcore/servers/serverbase.py
and./system/flcore/clients/clientbase.py
, respectively. -
To add a new model, just add it into
./system/flcore/trainmodel/models.py
. -
If you have a new optimizer while training, please add it into
./system/flcore/optimizers/fedoptimizer.py
-
The evaluation platform is also convenient for users to bulid a new platform for specific applications, such as our FL-IoT and HtFL.
If you are interested in the experimental results (e.g., the accuracy) of above algorithms, you can find some results in our accepted FL papers (i.e., FedALA, FedCP, GPFL, and DBE) listed as follows that also use this library. Please note that this developing project may not be able to reproduce the results on these papers, since some basic settings may change due to the requests of the community. For example, we previously set shuffle=False
in clientbase.py
