ImageClassification fails to load custom ResNet50 model with ".pt" file

Environment Details;

• OS: Windows 11
• Python Version: 3.12
• ImageAI Version: 3.0.3
• PyTorch Version: 2.5.1+cu118

Problem Description; When attempting to load a custom-trained ResNet50 model using ImageAI's ImageClassification, the model fails to load with the error: "Classification failed: Model not yet loaded. You need to call '.loadModel()' before performing image classification"

Reproduction Steps;

1. Initialize ImageClassification
2. Set model path using setModelPath()
3. Set model type using setModelTypeAsResNet50()
4. Call loadModel()

Code Snippet;

from imageai.Classification import ImageClassification

classifier = ImageClassification()
classifier.setModelPath("path/to/model.pt")
classifier.setModelTypeAsResNet50()
classifier.loadModel()  # Fails here

Additional Context; Model trained using custom dataset Model saved as '.pt' file Attempting to use for image classification

Questions; Does ImageAI support loading custom-trained models? Are there specific model export requirements?
