loss value

[BIG-PIE-MILK-COW]

Does anyone have trained text-conditional model? What about the loss value? I have trained the model on laion-art dataset, and the loss value finally decrease to around 0.1. Is it normal? Here are the sampled pictures.

[TheFusion21]

I've trained a model with about 13k pairs with 10k steps for each Unet and with a final loss of about 0.009 and get quiet the good text to image alignment

What cond_scale are you producing your samples with?

Try lower values... That said, text conditioning has seemed finicky in my experience.

Ok, thanks for your suggestion.

[BIG-PIE-MILK-COW]

Which dataset did you use? I guess that laion-art is too large, so I want to train on a smaller dataset

[deepglugs]

I'm training on danbooru-figures which is almost 900k images.

Do you have a model trained now? I would like to ask you about the specific value of the Unet parameter. The results I get so far are not good.The images I've gotten so far are rather blurry. @TheFusion21

This is my configuration. Unet 1 should optimaly have 512 in dim but I had to reduce it for memory reasons.

Thanks!

I still have a question, should I train Unet1, Unet2, and Unet3 separately or update the parameters of all three networks in one step?

[TheFusion21]

You can't train them together in one step

[QinSY123]

All right. Thanks!

@TheFusion21 Sorry to bother you again, but could you send me the checkpoint.pt of your training? I have sent an email to your email address.

Can't do it is trained on private data

@TheFusion21 When I use the command "imagen --model" to generate an image, it gives me the error "Command 'imagen' not found". Have you encountered the same problem?
