Hi @asanakoy @pesser @crowsonkb @theRealSuperMario @to3i I am retraining the LDMs, but the samples are bad. I want to konw, is the number of
batch size
will affect the sample progress and quality? I usebatch size
=36 andgpus
=3, but you setbatch size

hello, have you solved your problem about bad reproduced results? And i also account this problem when i trained ldm on CelebAHQ dataset.
hello,how to obtain these experimental analysis graphs above?
hello,how to obtain these experimental analysis graphs above?
In your logs there should be a folder named testtube, and inside (whichever version) there should be a tf folder containing an event file, refer to that event file with command like "tensorboard --logdir=tf", make sure you have tensorboard installed beforehand. Hope this works for you as well :)
