Before deployment, two steps require confirmation.
-
- Environment of software and hardware should meet the requirements. Please refer to FastDeploy Environment Requirements.
-
- FastDeploy Python whl package should be installed. Please refer to FastDeploy Python Installation.
This directory provides deployment examples that seq_cls_inferve.py fast finish text classification tasks on CPU/GPU.
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.
pip install -r requirements.txtThe following example shows how to employ FastDeploy library to complete Python predictive deployment of ERNIE 3.0 Medium model on AFQMC Datasetof CLUE Benchmark for text classification tasks.
# 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

# 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
