Optimize DeOldify setup script for efficiency and user feedback This …
…commit introduces several optimizations and enhancements to the DeOldify setup script, focusing on improving efficiency, user feedback, and error handling. Key changes include the implementation of an immediate check to avoid re-downloading already existing models, the use of tqdm for enhanced download progress reporting, streamlined dependency checking and installation, and consolidated feedback messages for already downloaded models and satisfied dependencies. These improvements aim to enhance the script's performance, reduce unnecessary operations, and provide clearer, more concise feedback to users.
### Summary of Changes
1. **Directory Creation Optimization**:
- Utilized `os.makedirs(models_dir, exist_ok=True)` to ensure the creation of the models directory if it does not exist, with `exist_ok=True` to avoid raising an error if the directory already exists. This change optimizes the directory creation step by making it more concise and efficient.
2. **Download Function Enhancement**:
- Added a check at the beginning of the `download` function to immediately return `False` if the file already exists, thus avoiding unnecessary download attempts and network traffic. This optimization ensures that the script does not attempt to re-download models that have already been downloaded, saving time and resources.
3. **Download Progress Reporting**:
- Implemented the use of `tqdm` in the `download` function for better progress reporting. This enhancement provides a visual progress bar during model downloads, offering real-time feedback on download progress and improving the user experience.
4. **Simplified Dependency Checking**:
- The `check_and_install_dependencies` function was refined to iterate through the list of dependencies and check if each is installed, and if not, to install it. This process is streamlined by splitting each dependency into its name and version (if specified), simplifying the handling of version-specific dependencies.
5. **Consolidated Feedback for Dependencies and Models**:
- Modified both the `download_models` and `check_and_install_dependencies` functions to provide consolidated feedback. If all models are already downloaded or if all dependencies meet the version requirements, a single message is printed, reducing output clutter. This change enhances the script's usability by providing clear and concise feedback about the status of models and dependencies.
6. **Error Handling in Download Function**:
- Improved error handling in the `download` function to catch exceptions and print a failure message, aiding in troubleshooting and enhancing the robustness of the model download process.
