在Mod(O_O)elScope中本地啟動(dòng)項目并設置web API接口是中置一個(gè)常見(jiàn)的需求,無(wú)論是(shi)本地并設為了測試還是部署,本文將詳細介紹如何在ModelScope中??本地啟??動(dòng)項目并設置web API接口。啟動(dòng)
(圖片來(lái)源網(wǎng)絡(luò ),項目侵刪)1. 環(huán)境準備
你需要確保你的中置計算機上已??經(jīng)安裝了Python和pip,Python是本地并設用于編寫(xiě)和運行項目的編程語(yǔ)言,而pip是啟動(dòng)Python的包管理器,用于安裝和管理Python庫。??項目
2.(╬?益?) 創(chuàng )建項目
在你的中置計算機上創(chuàng )建一個(gè)新的文件夾,例如my_project,本地并設然后在該文件夾中創(chuàng )建一個(gè)名為requ??irements.txt的啟??動(dòng)文件,用于列出項目所需的項目所有Python庫。
mkdir my_projectcd my_projecttouch re??quirements.txt在requirements.txt文件中,中置你可以添加以下內容:
Flask==1.1.2gunicorn==20.0.4
這些是本地并設啟動(dòng)項目所需的兩個(gè)Python庫:Flask和gunicorn,Fl??ask是啟動(dòng)一個(gè)輕量級的Web服務(wù)器網(wǎng)關(guān)接口(WSGI)Web應用框架,而gunicorn是一個(gè)Python WSGI HTTP服務(wù)器。
接下來(lái),使用pip安裝這??些庫:
pip instal┐(′ー`)┌l(fā) r requirements.txt
3. 編寫(xiě)代碼
在my_project文件夾中創(chuàng )建一個(gè)名為app.py的文(wen)件,然(ran)后添加以下(xia)內容:
from flask import Flask, request, jsonifyimport numpy as npimport pandas as pdimport joblibapp = Flask(__name__)model = joblib.load('model.pkl')@app.route('/predict', methods=['POST'])def pr??edict(): data = request.get_js??on()['data'] prediction = model.predict(data) return jsonify({?? 'prediction': prediction.tolist()})if __??name__ == '__main__': app.run(host='0.0.0.0', port=5000)這段代碼創(chuàng )建了一個(gè)簡(jiǎn)單的Flask應用,其中包含一個(gè)名為/predict的API接口,當客戶(hù)端向該接口發(fā)送POST請求時(shí),應用將使用預先訓練好的模型對請求中的數據進(jìn)行預測,并將預測結果作為JS??ON響應返回給客戶(hù)端。
4. 啟動(dòng)項目
在命令行中,導航到my_project文件夾,然后運行以下命令以啟動(dòng)項目:
