+# FS-TFP
+This is the offical repository of **FedDGCN**: A Scalable Federated Learning
 Framework for Traffic Flow Prediction.
 
 ![overview](./figures/overview.jpg)
 
-It is also a the traffic flow prediction extension based on FederatedScope.
+It is also a the traffic flow prediction extension based on [FederatedScope](https://github.com/alibaba/FederatedScope).
 
-NOTE:
+NOTE: This is an early version of **FedDGCN**. The full version will be updated after testing is completed.
 
+---
+
+# 1. Environment
+
+We run the experiment on a **Linux system**, i.e **Ubuntu 22.04**. It has not been tested on other systems yet.
+
+## Step 1. Create a Conda env
+
+We recommend using a **Conda** virtual environment. This project supports **Python 3.9** (recommended) and **Python 3.10**. 
+
+**WARNING: Python 3.11 and later versions are not compatible!**
+
+```
+conda create -n FedDGCN python=3.9
+conda activate FedDGCN
+```
+
+## Step 2. Install Pytorch
+
+Download the appropriate version of [PyTorch]( https://pytorch.org/get-started/locally/) based on your device.
+
+This project has been tested with **Torch 2.4.0 (recommended)** and **Torch 2.0.0** with **CUDA 12**. Compatibility with other versions is not guaranteed.
+
+## Step 3. Install FederatedScope 
+
+git clone this repository, and
+
+```
+cd FS-TFP
+pip install -e .
+```
+
+Additionally, you might need to install some extra packages to avoid annoying warnings.
+
+```
+pip install torch_geometric community rdkit
+```
+
+
+
+# 2. Run the Code
+
+## Step 1. Prepare the datasets
+
+You need to download the PeMS dataset from the **[STSGCN](https://github.com/Davidham3/STSGCN)** repository following README. After downloading, extract the dataset and place it in the `./data/trafficflow` directory at the root of the project.
+
+The directory structure of `./data/trafficflow` should be as follows:
+
+```
+FS-TFP\DATA\TRAFFICFLOW
+├─PeMS03
+├─PeMS04
+├─PeMS07
+└─PeMS08
+```
+
+## Step 2. Check your Setting
+
+We have placed the run scripts for the four datasets in the `./scripts/trafficflow_exp_scripts/` directory. 
+
+There are YAML files for four datasets: `{D3, D4, D7, D8}.yaml`.
+
+You can customize the parameters or use the presets we provide.
+
+Some key parameters include:
+
+```
+# Line 3: Adjust the GPU device to use (for multi-GPU machines)
+device: 0  
+
+# Line 8: Adjust the total number of training rounds
+total_round_num: <number_of_rounds>
+
+# Line 9: Adjust the number of clients based on your machine configuration
+client_num: <number_of_clients>
+
+# Line 65: Adjust the training loss function
+# Options: L1Loss, RMSE, MAPE
+criterion:
+  type: <loss_function>
+```
+
+**WARNING:** Processing the **PEMSD7** dataset may require more than **32GB** of memory. If your system lacks sufficient memory, it is recommended to increase the size of the swap partition.
+
+
+
+## Step 3. Run the experiments
+
+You can use the following command to run **FedDGCN** directly. It is recommended to create the corresponding run configuration in your IDE based on the command below:
+
+```
+# PEMSD3
+python federatedscope/main.py --cfg scripts/trafficflow_exp_scripts/D3.yaml
+# PEMSD4
+python federatedscope/main.py --cfg scripts/trafficflow_exp_scripts/D4.yaml
+# PEMSD7
+python federatedscope/main.py --cfg scripts/trafficflow_exp_scripts/D7.yaml
+# PEMSD8
+python federatedscope/main.py --cfg scripts/trafficflow_exp_scripts/D8.yaml
+```
+
+
+
+If you see the following output in your terminal, congratulations! You have successfully run the experiment:
+
+![image-20241121193843250](./figures/exp.png)
+
+
+
+# 3. Visualize the result
+
+The experiment logs will be placed in the **exp** folder. We have written a script, **global.py**, in the **exp** folder. You need to replace the previous logs with the new ones generated from the experiment. Once replaced, simply run the script to visualize the experiment results.
+
+```
+python exp/global.py
+```
+
+The script will generate a **baseline.jpg** file to visualize the logs. You are also free to modify the script to implement additional functionality as needed.
