Convert Pytorch pretrain -> TensoRT engine directly for CRAFT (Character-Region Awareness For Text detection)

• Convert CRAFT Text detection pretrain Pytorch model into TensorRT engine directly, without ONNX step between
  
• CRAFT: (forked from https://github.com/clovaai/CRAFT-pytorch) Official Pytorch implementation of CRAFT text detector | Paper | Pretrained Model | Supplementary
• Using torch2trt_dynamic from https://github.com/grimoire/torch2trt_dynamic (branch of https://github.com/NVIDIA-AI-IOT/torch2trt with dynamic shapes support)

Overview

Implementation of convenient converter from Pytorch to Tensor RT directly for CRAFT text detector. This repo is only about converting Pytorch model into Tensor RT. For Tensor RT inference, check out:

• Inference using Tensor RT standalone (https://github.com/k9ele7en/ONNX-TensorRT-Inference-CRAFT-pytorch)
• Advance inference pipeline using NVIDIA Triton Server (https://github.com/k9ele7en/triton-tensorrt-CRAFT-pytorch)

Getting started

1. Install dependencies

Requirements

$ pip install -r requirements.txt

Install ONNX, TensorRT

Check details at ./README_Env.md

2. Download the trained models
