Add secure dependency scanning to Claude Desktop with Socket MCP, a one-click extension that keeps your coding conversations safe from malicious packages.
SignAvatar Library Installation Guide
Python 3.7+: Make sure Python 3.7 or above is installed. Verify installation: Open a terminal and run python --version. pip: Python's package installer, used for installing dependencies. Verify installation: Run pip --version. Network Connection: A stable internet connection is required to install dependencies and retrieve online gesture resources if using URL-based videos. 2. Installation Steps Step 1: Download the SignAvatar Library Obtain the SignAvatar library code package. Clone from a repository (if hosted on GitHub or similar platform) using: bash Copy code git clone https://github.com/username/signavatar.git Or, download the library files as a .zip and extract them to your desired directory. Step 2: Install Required Dependencies Navigate to the directory containing the library files and install dependencies listed in requirements.txt.
bash Copy code cd signavatar pip install -r requirements.txt Note: The requirements file should include necessary packages such as requests for HTTP requests, json for JSON handling, and any additional dependencies used by the library.
ASLLVD/ WLASL Dataset:
Download the ASLLVD dataset (ASLLVD_videos.csv) or WLASL dataset (WLASL_videos.json). Place the downloaded dataset in the signavatar directory. File Structure Example:
Copy code signavatar/ ├── ASLLVD_videos.csv ├── WLASL_videos.json ├── signavatar.py ├── requirements.txt 4. Testing the Library Installation Once installed, test the library to verify that it is functioning as expected.
Open a Python environment (terminal or IDE).
Run the following code to initialize SignAvatar and display gesture URLs.
python Copy code from signavatar import SignAvatar
avatar = SignAvatar(language="ASL", style={"color": "blue", "brightness": 0.8}, expression="happy")
print("Loaded gestures:", len(avatar.gestures)) # Expected output: number of gestures loaded
print("Video URL for 'hello':", avatar.get_video_url("hello")) If successful, you should see output showing the loaded gestures and a video URL for the specified sign.
Test Animation Rendering: Run the following code to test the sign() method for rendering animations:
python Copy code animation_sequence = avatar.sign("Hello how are you?") print("Generated Animation Sequence:") for animation in animation_sequence: print(animation) This should return an animation sequence based on the phrase.
Copy the signavatar directory to your project’s directory.
Import and use SignAvatar methods in your project’s Python files:
python Copy code from signavatar import SignAvatar
avatar = SignAvatar() avatar.sign("Sample text to animate.") 6. Troubleshooting Module Not Found: Ensure the signavatar.py file is in the project’s root directory or PYTHONPATH. Missing Dependencies: Re-run pip install -r requirements.txt to install dependencies. Error Loading Gesture File: Confirm that the dataset file (e.g., ASLLVD_videos.csv) is present and named correctly.
