ppu-paddle-ocr/core/session-factory.d.ts

Lightweight, probably the fastest PaddleOCR SDK in TypeScript. Runs anywhere JavaScript runs: Node.js, Bun, Deno, mobile react-native, web browsers, and browser extensions. Docker & CLI supported. The official SDK is browser-only. Accurate text detection

 * Create an ORT session, retrying with a CPU/WASM-only provider list if the

 * Works around cases like `executionProviders: ["cuda", "cpu"]` on a host
 * without the CUDA runtime — ORT throws during session construction instead
 * of silently falling back to CPU. We catch that, log once, and retry with
 * whichever safe provider (`cpu` or `wasm`) was in the original list (or
 * default to `cpu` / `wasm` based on the ORT binding shape).
 *
 * Throws the original error if the provider list was already safe-only.
