2. urllib下载数据配置
from urllib.error import URLError from urllib.request import ProxyHandler, build_opener 参数是字典，键名是协议类型，健值是代理 proxy_handler = ProxyHandler({
'http': "http://127.0.0.1:12333", 'https': "http://127.0.0.1:12333" }) # Opener已经设置好代理了 opener = build_opener(proxy_handler) try: response = opener.open('http://httpbin.org/get') # 运行结果是一个JSON print(response.read().decode('utf-8')) except URLError as e: print(e.reason) Torch.geometirc dowload.py数据下载实例：
