Is there anyone success to train this model? #34
Comments
The reconstruction images are like solid image. |
Can you show the reconstruction images after training? |
@bridenmj How much epochs do you use? Are you working on the ImageNet Pretrain? |
Yes I'm working on ImageNet pretraining, It passed 12000 steps. The output image looks always the same. So, I tried LFQ in my own autoencoder, the training works well. It looks like there is something wrong in magvit2 model architecture. |
Actually I reimplement the model structure to align with the magvit2 paper. But I find that the LFQ Loss is negative and the recon loss will get converage easily with or without GAN. The reconstructed images are vague but not the solid color. What about you? @Jihun999 |
Ok, I will reimplement the model first. Thank you for your comment. |
Hey, is it possible to share the code modification for model architecture alignment? Thanks a lot! |
someone i know has trained it successfully. |
wow, could i know who did it. |
@RobertLuo1 @Jihun999 @lucidrains If you successfully trained this model, would you like to share the pretrained weights and the modified model code? |
Hello there, I tried with only MSE and then also the other losses, and also with/without attend_space layers. All work but I did not try to tune hyperparameters.. |
thank you for sharing this Marina! I'll see if I can find the bug, and worse comes to worse, can always rewrite the training code in pytorch lightning |
I tried to train this model few days. However, the reconstruction results always abnormal. If there is anyone success to train this model, can you tell me some tips for training?
