Load trained model and predict an image

hi,
I need load trained model and then want to predict output by testing an image. I have used the inception_v3 pre-trained model as a transfer learning model.
please list essential steps for load a model and predict an image.

model_ft = models.inception_v3(pretrained=True)
model_ft.aux_logits=False

i have saved model;
torch.save(model_ft.state_dict(),'PATH\model.pt')
so whats next?
