Error in depth estimation data preparation

[Yijia-Xiao]

Hi,

Thanks for the great work!
I am trying to finetune the depth estimation model on some other datasets. But I encountered errors preparing the downloaded datasets when I tried to train on the depth dataset you provided. Below are error information.
Thank you!

$ python prepare_demon_train.py

  img = imageio.imread(img.tobytes())

Hi, thanks for reporting this issue.

You issue seems to be the version issue of imageio, you can downgrade imageio to 2.9.0 with pip install imageio=2.9.0.

BTW, I just updated the depth data downloading script, where a small issue is fixed. Please re-download the depth data using the latest commit, sorry for the inconvenience.

Hi @haofeixu,

Thank you for your reply. I will try it out.
