# 或者只拿取小图在原图中的坐标rectangle, 小图在原图中的大小result，confidence表示准确率
res = img.find_coord()
# [{'result': (539.0, 21.5), 'rectangle': ((524, 10), (524, 33), (554, 10), (554, 33)), 'confidence': 1.0}]

from long_utils.storage.config import SSconfig
from long_utils.storage.aliyun.oss import AliyumOss

access_key = 'xxx'
access_key_secret = 'xxx'
endpoint = 'https://oss-cn-shanghai.aliyuncs.com'

分片下载文件到本地

aliyun_client.multipart_upload_file(key='xxx.pth', local_file='xxx.pth')

如果需要知道下载进度,可以:

def progress_callback(block_size, total_size):
    print(f"正在下载: {block_size / total_size * 100:.2f}%")

aliyun_client.multipart_upload_file(key='xxx.pth', local_file='xxx.pth', progress_callback=progress_callback)

分片上传本地文件

aliyun_client.multipart_upload_file(key='xxx.pth', file='xxxx.pth')

如果需要知道上传进度,可以:

def progress_callback(block_size, total_size):
    print(f"正在上传: {block_size / total_size * 100:.2f}%")

aliyun_client.multipart_upload_file(key='xxx.pth', file='xxx.pth', progress_callback=progress_callback)
