How to use pretrained model for prediction?

Hello there,
I have a pretrained model for Image Colorization using captions. The model was trained using the image, a caption and the features extracted using ResNet101. I have that model saved as .pth.tar file. I want to predict the output for an image, how can I load that model and use it for prediction?
Please help.


the common way would be this.

model = TheModelClass(*args, **kwargs)
