unexpected end of data while downloading the pdparam for EDVRPredictor

[franva]

I am in Australia and would like to use Paddle as well. It seems that the downloading of the pdparam file always too slow and ends up without downloading the full file which is indicated by the progress bar: 81920/82300, which leads to the unexpected end of data.

Are we thinking of adding some CDN for overseas users to speed up the downloading?
I have enrolled in 2 classes and hopefully I could use it in my project.

How to reproduce:

import paddle
paddle.set_device('gpu')

from ppgan.apps import EDVRPredictor
sr = EDVRPredictor()

frame_path, video_path = sr.run("video/result/TheProfessor.mp4")

你可以试试手动将权重保存到 https://paddlegan.bj.bcebos.com/applications/edvr_infer_model.tar to /home/winstonfan/.cache/ppgan/edvr_infer_model.tar 这个位置，并解压
