Pretrained model loss stuck around a point? how many epochs to train model?

[mukeshnarendran7]

How many epochs was the Transpose hA4 pre-trained model fine-tuned on the MPII dataset to get to the benchmarks in the paper?
I am using: the following parameters similar to the paper. but on a dataset with 10K images here
model_tp = torch.hub.load('yangsenius/TransPose:main',
'tph_a4_256x192',
pretrained=True)
model_tp.final_layer = torch.nn.Sequential(torch.nn.Conv2d(96, 18, kernel_size=1))

#Load parameters
model = model_tp.to(device)
pretrain_part = [param for name, param in model.named_parameters()if 'final_layer' not in name]
optimizer = torch.optim.Adam([ {'params': pretrain_part, 'lr':1e-5 },
{'params': model.final_layer.parameters(), 'lr': 1e-4}])
criterion = torch.nn.MSELoss(reduction="mean")

Any suggestion to improve would be helpful this situation. Thanks
I am training trying to fine-tune it but the loss doesn't decrease:

May I ask what is the reason for this

[adnantariq18]

I m getting -1.000 in all .. can anyone tell the reason ..

因为你需要把人体检测框标出来。他这个模型实际上是把人体检测框标出来之后才开始用Transformer进行关键点检测的。
