No such file or directory: '\\uploads\\03.jpeg'
相對路徑：加點，或者直接絕對路徑(盡量使用絕對路徑，通過python的os模塊獲取當前文件絕對路徑)
os.path.dirname(os.path.abspath(__file__)) 返回的是文件的目錄
os.path.abspath(__file__)返回的是.py文件的絕對路徑，包含文件名，並且返回path規范化的絕對路徑
相對路徑
../表示源文件所在目錄的上一級目錄，../../表示源文件所在目錄的上上級目錄，以此類推。
同級目錄直接文件名可以直接引用
./下一級目錄

Both /tmp and /static/uploads/.., are absolute paths. And your code is looking in the / folder instead of looking in your project's folder. You should use the absolute path to point at your folder /path/to/your/project/static/uploads/.. or use a path relative to the code being executed such as ./static/uploads.
You can also use the following snippet to generate the absolute path:
from os.path import join, dirname, realpath UPLOADS_PATH = join(dirname(realpath(__file__)), 'static/uploads/..')
