"""Unified launcher.
|
||
|
||
Examples:
|
||
python ocr.py data/images/手写01.png --device cpu
|
||
python ocr.py data/documents/sample.pdf --device cpu --pdf-mode hybrid
|
||
python ocr.py data/ --recursive --device cpu
|
||
python ocr.py benchmark --profile smoke --device cpu
|
||
python ocr.py verify --device gpu
|
||
|
||
The launcher deliberately executes the selected isolated uv project, so CPU
|
||
and GPU Paddle packages never share the same virtual environment.
