Can not reproduce the results of freeMatch about semi-supervised-learning

[qianlanwyd]

do you use pretrained vit? the results of paper are obtained using torchssl, it trained wide resnet from scratch.

error rate is 38%

Which config file are you using?

Hi, can you check the hyper-parameters in this file: https://drive.google.com/drive/folders/1oON5Vyjvb3vWxOQl7hdUl-eh0K-TEPPS.

The config file is slightly different from what we use for reporting the results.

Thanks for your response. I have checked the hyper-paprameter in my log. I found that clip_thresh was set to False in my log, which do not contain this arguments. However, I donot find clip_thresh in the config file. The following is my log

What's more, how many GPUs were used during the training process for this log? Will the number of GPUs have a significant impact on performance？

[weiliangwuw]

my result is 82.08,same as you ,but the results in paper the error rate is 36% the gap is too large what is the problem.

[weiliangwuw]

error rate is 38%

close as no one continues discussing, will re-open if it still has issues.
