# PPOCRv3 C++ multi-thread Deployment Example
|
|
|
|
This directory provides examples file `multi_thread_ocr.cc` to fast deploy PPOCRv3 on CPU/GPU and GPU accelerated by TensorRT.
|
|
|
|
Two steps before deployment
|
|
|
|
- 1. Software and hardware should meet the requirements. Please refer to [FastDeploy Environment Requirements](../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)
|
|
- 2. Download the precompiled deployment library and samples code according to your development environment. Refer to [FastDeploy Precompiled Library](../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)
|
|
|
|
Taking the PPOCRv3 inference on Linux as an example, the compilation test can be completed by executing the following command in this directory. FastDeploy version 0.7.0 or above (x.x.x>=0.7.0) is required to support this model.
|
|
|
|
```bash
|
|
mkdir build
|
|
cd build
|
|
# Download the FastDeploy precompiled library. Users can choose your appropriate version in the `FastDeploy Precompiled Library` mentioned above
|
|
wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-x.x.x.tgz
|
|
tar xvf fastdeploy-linux-x64-x.x.x.tgz
|
|
cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-x.x.x
