# Environment Setup Specification
|
|
|
|
## ADDED Requirements
|
|
|
|
### Requirement: GPU Detection and CUDA Installation
|
|
The system SHALL automatically detect compatible GPU hardware during environment setup and install appropriate PaddlePaddle packages (GPU-enabled or CPU-only) based on hardware availability.
|
|
|
|
#### Scenario: GPU detected with CUDA support
|
|
- **WHEN** setup script runs on system with NVIDIA GPU and CUDA drivers
|
|
- **THEN** the script detects GPU using `nvidia-smi` command
|
|
- **AND** determines CUDA version from driver
|
|
- **AND** installs `paddlepaddle-gpu` with matching CUDA version
|
|
- **AND** verifies GPU availability through Python
|
|
- **AND** displays GPU information (device name, CUDA version, memory)
|
|
|
|
#### Scenario: No GPU detected
|
|
- **WHEN** setup script runs on system without compatible GPU
|
|
- **THEN** the script detects absence of GPU hardware
|
|
- **AND** installs CPU-only `paddlepaddle` package
|
|
- **AND** displays message that CPU mode will be used
|
|
- **AND** continues setup without errors
|
|
|
|
#### Scenario: GPU detected but no CUDA drivers
|
|
- **WHEN** setup script detects NVIDIA GPU but CUDA drivers are missing
|
|
- **THEN** the script displays warning about missing drivers
|
|
- **AND** provides installation instructions for CUDA drivers
|
|
- **AND** falls back to CPU-only installation
|
|
- **AND** suggests re-running setup after driver installation
|
|
|
|
#### Scenario: CUDA version mismatch
|
|
- **WHEN** detected CUDA version is not compatible with available PaddlePaddle packages
|
|
- **THEN** the script displays available CUDA versions
|
|
- **AND** installs closest compatible PaddlePaddle GPU package
|
|
- **AND** warns user about potential compatibility issues
|
|
- **AND** provides instructions to upgrade/downgrade CUDA if needed
|
|
|
|
#### Scenario: Manual CUDA version override
|
|
- **WHEN** user sets CUDA_VERSION environment variable before running setup
|
|
- **THEN** the script uses specified CUDA version instead of auto-detection
|
|
- **AND** installs corresponding PaddlePaddle GPU package
|
|
- **AND** skips automatic CUDA detection
|
|
- **AND** displays warning if specified version differs from detected version
|
|
|
|
### Requirement: GPU Verification
|
|
The system SHALL verify GPU functionality after installation and provide clear status reporting.
|
|
|
|
#### Scenario: Successful GPU setup verification
|
|
- **WHEN** PaddlePaddle GPU installation completes
|
|
- **THEN** the script runs GPU availability test using Python
|
|
- **AND** confirms CUDA devices are accessible
|
|
- **AND** displays GPU count, device names, and memory capacity
|
|
- **AND** marks GPU setup as successful
|
|
|
|
#### Scenario: GPU verification fails
|
|
- **WHEN** GPU verification test fails after installation
|
|
- **THEN** the script displays detailed error message
|
|
- **AND** provides troubleshooting steps
|
|
- **AND** suggests fallback to CPU mode
|
|
- **AND** does not fail entire setup process
|
|
|
|
### Requirement: Environment Configuration for GPU
|
|
The system SHALL create appropriate configuration settings for GPU usage in environment files.
|
|
|
|
#### Scenario: GPU-enabled configuration
|
|
- **WHEN** GPU is successfully detected and verified
|
|
- **THEN** the setup script adds GPU settings to `.env.local`
|
|
- **AND** sets `FORCE_CPU_MODE=false`
|
|
- **AND** sets detected `CUDA_VERSION`
|
|
- **AND** sets recommended `GPU_MEMORY_FRACTION` (e.g., 0.8)
|
|
- **AND** adds GPU-related comments and documentation
|
|
|
|
#### Scenario: CPU-only configuration
|
|
- **WHEN** no GPU is detected or verification fails
|
|
- **THEN** the setup script creates CPU-only configuration
|
|
- **AND** sets `FORCE_CPU_MODE=true`
|
|
- **AND** omits or comments out GPU-specific settings
|
|
- **AND** adds note about GPU requirements
