Basic introductory guide for connecting Python and Baidu AI interface

Introduction:

With the rapid development of artificial intelligence technology, Baidu AI interface provides many powerful features and services. As a powerful and easy-to-learn programming language, Python is particularly convenient to interface with Baidu AI. This article will introduce some common Baidu AI interfaces and provide corresponding Python code examples to help readers get started quickly.

1. Baidu speech recognition interface:

The Baidu speech recognition interface can be used to convert speech into text to realize speech recognition function. First, we need to import Baidu AI’s SDK. You can use the Python SDK officially provided by Baidu AI. The following is a simple sample code:

import json import base64 import requests API_KEY = 'your_api_key' SECRET_KEY = 'your_secret_key' def get_access_token(): url = 'https://aip.baidubce.com/oauth/2.0/token' data = { 'grant_type': 'client_credentials', 'client_id': API_KEY, 'client_secret': SECRET_KEY } response = requests.post(url, data=data) result = json.loads(response.text) if 'access_token' in result: return result['access_token'] else: return None def speech_to_text(file_path): access_token = get_access_token() url = 'https://vop.baidu.com/pro_api' with open(file_path, 'rb') as f: speech_data = f.read() speech_base64 = base64.b64encode(speech_data).decode('utf-8') data = { 'dev_pid': 1536, 'format': 'pcm', 'rate': 16000, 'token': access_token, 'cuid': 'your_cuid', 'channel': 1, 'speech': speech_base64, 'len': len(speech_data) } headers = {'Content-Type': 'application/json'} response = requests.post(url, data=json.dumps(data), headers=headers) result = json.loads(response.text) if 'result' in result: return result['result'] else: return None file_path = 'path_to_your_audio_file' result = speech_to_text(file_path) print(result)

In the code, you first need to replace API_KEY and SECRET_KEY with your Baidu AI authentication information. Then, get the access token via theget_access_tokenfunction, and then use thespeech_to_textfunction to convert the audio file to text.

2. Baidu image recognition interface:

The Baidu image recognition interface can be used to identify objects, scenes, text, etc. in images. Similarly, we need to import Baidu AI's SDK and replace API_KEY and SECRET_KEY. The following is a simple sample code:

import requests import base64 import json API_KEY = 'your_api_key' SECRET_KEY = 'your_secret_key' def get_access_token(): url = 'https://aip.baidubce.com/oauth/2.0/token' data = { 'grant_type': 'client_credentials', 'client_id': API_KEY, 'client_secret': SECRET_KEY } response = requests.post(url, data=data) result = json.loads(response.text) if 'access_token' in result: return result['access_token'] else: return None def image_classify(file_path): access_token = get_access_token() url = 'https://aip.baidubce.com/rest/2.0/image-classify/v2/advanced_general' with open(file_path, 'rb') as f: image_data = f.read() image_base64 = base64.b64encode(image_data).decode('utf-8') data = { 'image': image_base64 } params = { 'access_token': access_token } headers = {'Content-Type': 'application/x-www-form-urlencoded'} response = requests.post(url, data=data, params=params, headers=headers) result = json.loads(response.text) if 'result' in result: return result['result'] else: return None file_path = 'path_to_your_image_file' result = image_classify(file_path) print(result)

Copy after login

In the code, API_KEY and SECRET_KEY also need to be replaced. Then, obtain the access token through theget_access_tokenfunction, and then use theimage_classifyfunction to identify objects in the image.

Conclusion:

This article introduces the basic introductory guide for connecting Python and Baidu AI interface, and provides sample code for speech recognition and image recognition. I hope readers can use these sample codes to get started quickly and further explore other functions and services of Baidu AI. By combining Baidu AI with Python, we can provide us with more convenient and powerful artificial intelligence applications.
