The model can be loaded using: |
|
``` |
|
from huggingface_hub import hf_hub_download |
|
import torch |
|
|
|
# Specify the repository and the filename of the model you want to load |
|
repo_id = "FinalProj5190/ImageToGPSproject_new_vit" # Replace with your repo name |
|
filename = "resnet_gps_regressor_complete.pth" |
|
|
|
model_path = hf_hub_download(repo_id=repo_id, filename=filename) |
|
|
|
# Load the model using torch |
|
model_test = torch.load(model_path) |
|
model_test.eval() # Set the model to evaluation mode |
|
``` |
|
|
|
The model implementation is here: |
|
``` |
|
class MultiModalModel(nn.Module): |
|
def __init__(self, num_classes=2): |
|
super(MultiModalModel, self).__init__() |
|
self.vit = ViTModel.from_pretrained('google/vit-base-patch16-224-in21k') |
|
|
|
# Replace for regression instead of classification |
|
self.regression_head = nn.Sequential( |
|
nn.Linear(self.vit.config.hidden_size, 512), |
|
nn.ReLU(), |
|
nn.Linear(512, num_classes) |
|
) |
|
|
|
def forward(self, x): |
|
outputs = self.vit(pixel_values=x) |
|
# Take the last hidden state (CLS token embedding) |
|
cls_output = outputs.last_hidden_state[:, 0, :] |
|
# Pass through the regression head |
|
gps_coordinates = self.regression_head(cls_output) |
|
return gps_coordinates |
