logfile is not showing any runs for the test set. The plots also don't show anything for test set and accuracy.

When I run the code, I get the following output:

I have also attached my logfile with this. When I run the plot function, I get empty plots for everything apart from training loss. Please let me know where the issue might be. Thanks.

Hi @saharudra, this issue is probably due to a batch handling issue on the Multi GPU setup. You should be able to run the code by simply removing the condition (the entire line): https://github.com/mesnico/RelationNetworks-CLEVR/blob/b8e0e7af12408877c8a18d8f2802d88138605983/model.py#L196 This is not the most efficient solution; however, if that is the problem, I will fix it permanently as soon as possible using a better approach. Thanks!

Hi @mesnico, I will give this a try and let you know the outcome here. Thanks!
