Questions on generating flow #26

Closed golddohyun closed 1 year ago

golddohyun commented 1 year ago

Thank you for your source code! I want to train your model by using Vimeo90k data. I tried to run the generate_flow.py but I've got these errors. On your code on run.py of liteflownet, I've realized that the 297th line on the run.py might have a problem. I accessed the link ("http://content.sniklaus.com/github/pytorch-liteflownet") where the error occurred directly, but the page of the link seems to have disappeared. When I tried the actual connection, only the phrase "no so much file or directory" came out.

and below is the error printed on my log.txt file!

To solve your problems, I suggest that:

  1. Comment out this line of code and umcomment this line of code in ./liteflownet/run.py.
  2. Download the pre-trained LiteFlowNet parameters in this link, and then put the file network-default.pth into the dir of ./liteflownet/network-default.pth.

It worked! thank you so much :)
