# Example of ERNIE 3.0 Models Python Deployment
|
||
|
||
Before deployment, two steps require confirmation.
|
||
|
||
- 1. Environment of software and hardware should meet the requirements. Please refer to [FastDeploy Environment Requirements](../../../../docs/en/build_and_install/download_prebuilt_libraries.md).
|
||
- 2. FastDeploy Python whl package should be installed. Please refer to [FastDeploy Python Installation](../../../../docs/en/build_and_install/download_prebuilt_libraries.md).
|
||
|
||
This directory provides deployment examples that seq_cls_inferve.py fast finish text classification tasks on CPU/GPU.
|
||
|
||
## Dependency Installation
|
||
|
||
The Python Predictor in this project uses AutoTokenizer provided by PaddleNLP to conduct word segmentation and fast_tokenizer to speed up word segmentation. Run the following command to install it.
|
||
|
||
```bash
|
||
pip install -r requirements.txt
|
||
```
|
||
|
||
|
||
## Text Classification Tasks
|
||
|
||
### A Quick Start
|
||
|
||
The following example shows how to employ FastDeploy library to complete Python predictive deployment of ERNIE 3.0 Medium model on [AFQMC Dataset](https://bj.bcebos.com/paddlenlp/datasets/afqmc_public.zip)of CLUE Benchmark for text classification tasks.
|
||
|
||
```bash
|
||
|
||
# Download the deployment example code
|
||
git clone https://github.com/PaddlePaddle/FastDeploy.git
|
||
cd FastDeploy/examples/text/ernie-3.0/python
|
||
|
||
# Download fine-tuned ERNIE 3.0 models for AFQMC dataset
|
||
wget https://bj.bcebos.com/fastdeploy/models/ernie-3.0/ernie-3.0-medium-zh-afqmc.tgz
|
||
tar xvfz ernie-3.0-medium-zh-afqmc.tgz
|
||
|
||
# CPU Inference
|
||
python seq_cls_infer.py --device cpu --model_dir ernie-3.0-medium-zh-afqmc
|
||
|
||
# GPU Inference
|
||
python seq_cls_infer.py --device gpu --model_dir ernie-3.0-medium-zh-afqmc
|
||
|
||
# KunlunXin XPU Inference
|
||
python seq_cls_infer.py --device kunlunxin --model_dir ernie-3.0-medium-zh-afqmc
|
||
|
||
```
|
||
The result returned after running is as follows:
|
||
|
||
|
||
```bash
|
||
[INFO] fastdeploy/runtime.cc(469)::Init Runtime initialized with Backend::ORT in Device::CPU.
|
||
Batch id:0, example id:0, sentence1:花呗收款额度限制, sentence2:收钱码，对花呗支付的金额有限制吗, label:1, similarity:0.5819
|
||
Batch id:1, example id:0, sentence1:花呗支持高铁票支付吗, sentence2:为什么友付宝不支持花呗付款, label:0, similarity:0.9979
|
||
```
|
||
|
||
### Parameter Description
|
||
|
||
`seq_cls_infer.py`supports more command-line arguments in addition to the preceding example. The following is a description of every command-line argument
|
||
|
||
| Parameter | Parameter Description |
|
||
|----------|--------------|
|
||
|--model_dir | Specify the directory where the model is to be deployed |
|
||
|--batch_size |Maximum measurable batch size, default 1|
|
||
|--max_length |Maximum sequence length, default 128|
|
||
|--device | Running devices, optional range: ['cpu', 'gpu'], default 'cpu' |
|
||
|--backend | Supported inference backend, optional range: ['onnx_runtime', 'paddle', 'openvino', 'tensorrt', 'paddle_tensorrt']，default 'onnx_runtime' |
|
||
|--use_fp16 | Whether to use FP16 mode for inference.Enabled when using tensorrt and paddle tensorrt backend, and default is False |
|
||
|--use_fast| Whether to use FastTokenizer to speed up the tokenization, and default is True|
