i read the code,find dataset=Mpiigaze(testlabelpathombined,args.gazeMpiimage_dir, transformations, True, fold) give 5 paramters ,but class Mpiigaze(Dataset):
def init(self, pathorg, root, transform, train, angle,fold=0): accept 6 paramters ,is there any bug?

when i guess angel=180,the train also meet other bug:
Traceback (most recent call last):
File "train.py", line 299, in
{'params': get_ignored_params(model, args.arch), 'lr': 0},
TypeError: get_ignored_params() takes 1 positional argument but 2 were given

hi @zpz915 , have you succeeded training the model. I am also facing the same issue.

[forlayo]

Same issue here, any solutions ?

[yakhyo]

@forlayo , I succeeded training Gaze360 and going to release it soon and adding mobilenet new backbone as well.

I tried to download the dataset but it seems like the dataset is too big, can anyone split the dataset for me around 5gb so I can download it?

[yakhyo]

@tiamo405 , MPIIFaceGaze is relatively smaller than Gaze360.

I have identified and resolved issues in the code, and understand why using the Gaze360 dataset can result in successful training while using the MPIIFaceGaze dataset reports errors. This is because MPIIFaceGaze data processing lacks an angle parameter, and all data with angles less than 0 degrees are filtered out.

我已经识别并解决了代码中的问题，并了解了为什么使用 Gaze360 数据集可以成功训练，而使用 MPIIFaceGaze 数据集报告错误。这是因为 MPIIFaceGaze 数据处理缺少 angle 参数，所有角度小于 0 度的数据都会被过滤掉。

Hello, so how did you solve the problem, just delete the parameter or add the code to handle the angle parameter?

[yakhyo]

@NuoZ , i resolved the problem and reproduced some of the results.

您好，那么您是怎么解决问题的，只是删除参数还是添加代码来处理 angle 参数呢？
like this dataset=Mpiigaze(testlabelpathombined,args.gazeMpiimage_dir, transformations, True,180, fold)

Sorry. This is my first pull request, so I was a bit clumsy. Please feel free to look at my commit.
