help with training

[y-x-c]

Thanks for the awesome code! I am training my own model right now and have a few questions:

• currently I am using 100k (out of around 1.8m) images from CelebAMask-HQ, ffhq and vggface to train the model. did you use the full set to train your model?
• I didn't see large improvement for most losses anymore (160k steps trained, 4gpus x 12images/batch); is this normal? should I just continue training for more steps?
• I also checked the validation results, and the reconstruction is not good.
• I noticed shuffle for the training dataloader is not set to True, did you use the same setting?

Thanks!

Hi! You did very fast training!

1. Yes, I used full-set dataset. I don't know about IJB-C dataset. The distribution of dataset can influence to your model.

2. In the paper, they trained for 500K steps. I trained for over 500K. In my eye, your losses are getting down for attribute_loss but unstable for Rec and ID loss. In my case, the two losses are more stable and lower at the same steps.

3. shuffle option in training dataloader should be True. It is clearly my mistake while publishing.

Thanks for your reply.

1. I just corrected the description, I am using the same datasets (CelebAMask-HQ, ffhq and vggface) as well.

• So in your case, each step has 64 images; and let's say there are 1.5m images in those three datasets, so you trained for around 4 epochs (= 64 * 500000 / 1500000 / 5 ) in total?
• In my case, each step only has 48 images, so maybe that's why the two losses are higher at the same steps.
• I found the Rec loss is going much lower in the third epoch, and the results are much better than before. I will continue my current training and see what's going on.

3. Thanks for the clarification, I also changed to True during my training.

• I trained with 32 batch size, it is the same as the paper. (Two V100 32G GPUs, 16 batch size for each)

• Training GAN is very unstable. If your loss is going down, I think it works well.

Hi, did you change the coefficients of different loss terms? I found my training unstable with the coeffs provided by the author...

it means that you have used 'dp' instead of 'ddp'? since in 'ddp' mode the whole batch is not devided between GPUs.

@y-x-c Hi, have you got the satisfying result? I trained just with FFHQ and CelebA-HQ datasets about 90 thousand images. The result is bad just like below.

[princessmittens]

By 4 epoch's you mean 26...

I am about two weeks into training at about the halfway mark. I noticed that some of the results on the colab show some image artifacts. Is that present in all final results? Did you manage to fix that with more training?

@princessmittens I am also working on this paper and I have some questions about this implementation. May I have your email address?

@usingcolor I am near the end of training and these are my results. I have trained on 8 gpu's with 32 gig ram and a 21 batch size/ per gpu. The results have been pretty bad so far. I tried my best to recreate the exact parameters with all 3 datasets (~1.3 million images after processing) and have trained for about 2-3 weeks. With my current batch size and according to the results, I'm at the 79% mark in reference to 500k.

@y-x-c -Have you been able to recreate better results? Is it worth continuing?

This has cost a lot of money/time Any input would be great.

@hanikh Not sure how much I can help you considering my results but my email is <>

Hello, anyone here got good result?

[princessmittens]

No-I have talked to @hanikh. I don't think anyone has been able to recreate the results as of yet.

[aesanchezgh]

I have better results than this, princessmittens, can you leave your e-mail and I will reach out to you?

No-I have talked to @hanikh. I don't think anyone has been able to recreate the results as of yet.
