What is inside your brm.7z file (e.g., images, CSVs, or R model files)?

Resize or normalize the extracted files to match the input requirements of your chosen model.

Use a pre-trained Convolutional Neural Network (CNN) like ResNet50 . You can load the model in TensorFlow or PyTorch, remove the final "head" (the classification layer), and run the predict method on your images to get high-dimensional feature vectors.
