VIT input size transform 224 to another

[Chaoran-F]

Dear author, I saw in your code said "Vit model input can transform 224 to another, we use linear", but I do not know how to use it. I tried to use 384*384 as my input size directly, but it shows me a tensor cannot match issues, so I have to resize my input data, but there are same issues when I detect my test data, so can I know how to use transform 224 to another, or I just need to add a linear layer before I input my datasets?

Thanks
