| # 📡 **LWM: Large Wireless Model** | |
| **[🚀 Click here to try the Interactive Demo!](https://huggingface.co/spaces/sadjadalikhani/lwm-interactive-demo)** | |
| Welcome to **LWM** (Large Wireless Model) — a pre-trained model designed for processing and feature extraction from wireless communication datasets, particularly the **DeepMIMO** dataset. This guide provides step-by-step instructions to set up your environment, install the required packages, clone the repository, load data, and perform inference using LWM. | |
| --- | |
| ## 🛠 **How to Use** | |
| ### 1. **Install Conda** | |
| First, ensure that you have a package manager like **Conda** installed to manage your Python environments and packages. | |
| #### **Install Conda** | |
| You can install **Conda** via **Anaconda** or **Miniconda**. | |
| - **Anaconda** includes a comprehensive scientific package suite. Download it [here](https://www.anaconda.com/products/distribution). | |
| - **Miniconda** is a lightweight version that includes only Conda and Python. Download it [here](https://docs.conda.io/en/latest/miniconda.html). | |
| Once installed, you can use Conda to manage environments. | |
| --- | |
| ### 2. **Create a New Environment** | |
| After installing Conda (https://conda.io/projects/conda/en/latest/user-guide/install/index.html), follow these steps to create a new environment and install the required packages. | |
| #### **Step 1: Create a new environment** | |
| Create a new environment named `lwm_env`: | |
| ```bash | |
| conda create -n lwm_env | |
| ``` | |
| #### **Step 2: Activate the environment** | |
| Activate the environment: | |
| ```bash | |
| conda activate lwm_env | |
| ``` | |
| --- | |
| ### 3. **Install Required Packages** | |
| Once the environment is activated, install the necessary packages. | |
| #### **Install CUDA-enabled PyTorch** | |
| While inference runs efficiently on CPU, you may require a GPU for training downstream tasks. Follow the instructions below to install CUDA-enabled PyTorch. Be sure to adjust the `pytorch-cuda` version according to your system's specifications. | |
| ```bash | |
| conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia | |
| ``` | |
| > **Note:** If you encounter issues installing CUDA-enabled PyTorch, verify your CUDA version compatibility. It might also be due to conflicting installation attempts—try a fresh environment. | |
| #### **Install Other Required Packages via Conda Forge** | |
| ```bash | |
| conda install python numpy pandas matplotlib tqdm -c conda-forge | |
| ``` | |
| #### **Install DeepMIMOv3 with pip** | |
| ```bash | |
| pip install DeepMIMOv3 | |
| ``` | |
| --- | |
| ### 4. **Clone the Dataset Scenarios** | |
| The following functions will help you clone specific dataset scenarios from a repository: | |
| ```python | |
| import subprocess | |
| import os | |
| # Function to clone a specific dataset scenario folder | |
| def clone_dataset_scenario(scenario_name, repo_url, model_repo_dir="./LWM", scenarios_dir="scenarios"): | |
| # Create the scenarios directory if it doesn't exist | |
| scenarios_path = os.path.join(model_repo_dir, scenarios_dir) | |
| if not os.path.exists(scenarios_path): | |
| os.makedirs(scenarios_path) | |
| scenario_path = os.path.join(scenarios_path, scenario_name) | |
| # Initialize sparse checkout for the dataset repository | |
| if not os.path.exists(os.path.join(scenarios_path, ".git")): | |
| print(f"Initializing sparse checkout in {scenarios_path}...") | |
| subprocess.run(["git", "clone", "--sparse", repo_url, "."], cwd=scenarios_path, check=True) | |
| subprocess.run(["git", "sparse-checkout", "init", "--cone"], cwd=scenarios_path, check=True) | |
| subprocess.run(["git", "lfs", "install"], cwd=scenarios_path, check=True) # Install Git LFS if needed | |
| # Add the requested scenario folder to sparse checkout | |
| print(f"Adding {scenario_name} to sparse checkout...") | |
| subprocess.run(["git", "sparse-checkout", "add", scenario_name], cwd=scenarios_path, check=True) | |
| # Pull large files if needed (using Git LFS) | |
| subprocess.run(["git", "lfs", "pull"], cwd=scenarios_path, check=True) | |
| print(f"Successfully cloned {scenario_name} into {scenarios_path}.") | |
| ``` | |
| --- | |
| ### 5. **Clone the Model Repository** | |
| Now, clone the **LWM** model repository to your local system. | |
| ```bash | |
| # Step 1: Clone the model repository (if not already cloned) | |
| model_repo_url = "https://huggingface.co/sadjadalikhani/lwm" | |
| model_repo_dir = "./LWM" | |
| if not os.path.exists(model_repo_dir): | |
| print(f"Cloning model repository from {model_repo_url}...") | |
| subprocess.run(["git", "clone", model_repo_url, model_repo_dir], check=True) | |
| ``` | |
| --- | |
| ### 6. **Clone the Desired Dataset Scenarios** | |
| You can now clone specific scenarios from the DeepMIMO dataset, as detailed in the table below: | |
| 📊 **Dataset Overview** | |

| #### **Clone the Scenarios:** | |
| ```python | |
| dataset_repo_url = "https://huggingface.co/datasets/sadjadalikhani/lwm" # Base URL for dataset repo | |
| scenario_names = np.array([ | |
| "city_18_denver", "city_15_indianapolis", "city_19_oklahoma", | |
| "city_12_fortworth", "city_11_santaclara", "city_7_sandiego" | |
| ]) | |
| scenario_idxs = np.array([0, 1, 2, 3, 4, 5]) # Select the scenario indexes | |
| selected_scenario_names = scenario_names[scenario_idxs] | |
| # Clone the requested scenarios | |
| clone_dataset_scenarios(selected_scenario_names, dataset_repo_url, model_repo_dir) | |
| ``` | |
| --- | |
| ### 7. **Change the Working Directory to LWM** | |
| ```bash | |
| if os.path.exists(model_repo_dir): | |
| os.chdir(model_repo_dir) | |
| print(f"Changed working directory to {os.getcwd()}") | |
| else: | |
| print(f"Directory {model_repo_dir} does not exist. Please check if the repository is cloned properly.") | |
| ``` | |
| --- | |
| ### 8. **Tokenize and Load the Model** | |
| Now, tokenize the dataset and load the pre-trained LWM model. | |
| ```python | |
| from input_preprocess import tokenizer | |
| from lwm_model import lwm | |
| import torch | |
| preprocessed_chs = tokenizer( | |
| selected_scenario_names=selected_scenario_names, | |
| manual_data=None, | |
| gen_raw=True | |
| ) | |
| device = 'cuda' if torch.cuda.is_available() else 'cpu' | |
| print(f"Loading the LWM model on {device}...") | |
| model = lwm.from_pretrained(device=device) | |
| ``` | |
| --- | |
| ### 9. **Perform Inference** | |
| You can now perform inference on the preprocessed data using the LWM model. | |
| ```python | |
| from inference import lwm_inference, create_raw_dataset | |
| input_types = ['cls_emb', 'channel_emb', 'raw'] | |
| selected_input_type = input_types[0] | |
| if selected_input_type in ['cls_emb', 'channel_emb']: | |
| dataset = lwm_inference(preprocessed_chs, selected_input_type, model, device) | |
| else: | |
| dataset = create_raw_dataset(preprocessed_chs, device) | |
| ``` | |
