Hi,
if you are not using the pretrained backbone, please set ‘lr’ and ‘lr_backbone’ the same
I changed my config file as below:
trainset_3d: ['Human36M', 'MuCo']
trainset_2d: ['MSCOCO', 'MPII']
testset: 'PW3D'
lr_dec_epoch: [30]
end_epoch: 40
lr: 0.0005
lr_backbone: 0.0005
lr_dec_factor: 10
# modify batch size
train_batch_size: 128
test_batch_size: 128
However, the results were still weird.
Hi,
Yes, the results seem weird.
Are you evaluating on 3DPW-Crowd?
How can you train that fast? I don’t remember exactly, but it took about more than 12hours to train for 6epochs. You are training for 40epochs with half batch size. 2days are not enough.
Wow, I didn't know that RTX 3090 is that better than RTX 2080 ti.
I thought you were testing on 3DPW-Crowd, since you are using 3dpw_crowd.yml
My training command is python train.py --amp --gpu 0 --cfg ../assets/yaml/3dpw_crowd.yml
Can you share your full code via github repo? Some information is confusing. Increasing errors seem really weird.
So sorry that I pasted the wrong command.
My training command is python train.py --amp --gpu 0 --cfg ../assets/yaml/3dpw.yml
This is my full code: https://github.com/mimiliaogo/3DCrowdNet-Mimi
Thank you so much!
Thanks for sharing the code. I can't find a critical bug...
Here are a few suggestions.
Could you try testing with the test.py
? Due to the evaluation per epoch, there could be unintentional overwriting in the testing data during the process.
Could you visualize the training data? Visualize GT joints and meshes on the image. There could be corruption during downloading. And is there any change in MPII.py
code?
Could you train with this config info and see the result? It shouldn't take long. It's to see which dataset is causing the increasing error.

Hi, I tried your conifg as 3., the results seem normal.
So maybe the problem is from training data. I will try to visualize them. BTW, there is no change in MPII.py code.
@hongsukchoi, when I train your model with Human3.6M and MuCo respectively, both of them will have increasing errors.
I visualize the GT keypoints and joints, and the results seem normal (maybe a little inaccurate, but mostly right).
However, I still don't know why these two datasets will lead to increasing errors...
Hi, I tried to reproduce table 8 without pre-trained ResNet-50 weights of xiao2018simple. My training command is
python train.py --amp --gpu 0 --cfg ../assets/yaml/3dpw_crowd.yml
and the config file is :However, I got very strange results on 3dpw as below (I evaluate every epoch):
Do you have any idea about this? Thank you!
