The key changes made in the updated installation script~:
Refactoring and Simplification: The updated script has been refactored for better readability and maintainability. Functions like get_installed_version and install_package are introduced to reduce code repetition and make the script more modular.
Version Checks and Updates:
The tensorrt package version has been updated from 9.0.1.post11.dev4 to 9.3.0.post12.dev1. This change indicates a significant version update, possibly including new features, bug fixes, and performance improvements.
The CUDA Deep Neural Network library (nvidia-cudnn-cu11) dependency has been replaced with nvidia-cudnn-cu12 in the updated script, suggesting a move to support newer CUDA versions (cu12 instead of cu11). However, there seems to be a discrepancy in the version handling (8.9.7.29 vs. 8.9.6.50) that might be a typo or an intentional downgrade for compatibility reasons.
Improved Package Management:
The updated script includes more sophisticated logic for managing package installations, including handling uninstallation of previous versions if needed, before installing a new version. This is especially evident in the handling of the tensorrt and nvidia-cudnn-cu12 packages.
The addition of no_cache_dir=True to all install_package calls to ensure the latest versions are fetched and to avoid potential conflicts with cached packages.
Simplified Dependency Handling:
The dependencies for ONNX Graph Surgeon and Polygraphy are handled more straightforwardly in the updated script, with specific versions for dependent packages like protobuf.
Error Handling and Robustness: The introduction of the get_installed_version function allows for more robust error handling by checking if a package is installed and obtaining its version before attempting to install or uninstall. This reduces the risk of errors during the installation process.
