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

[KaleBats123]

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?
