How is features_train.pth generated for generate_cost_matrix?

[agrichron]

Description

In the generate_cost_matrix.py script, the file features_train.pth is used as input data. However, the repository does not provide specific instructions or scripts on how this file is generated. To better understand and use this code, I would appreciate it if you could provide the following information:

What does the features_train.pth file contain?
    Does this file contain feature representations from a model? If so, which model is used?
    What is the structure of the file? (e.g., tensor shape, data type, etc.)
How is the features_train.pth file generated?
    Is there a specific script or tool used to generate this file?
    If it is generated by extracting features from a model, could you provide the relevant code or steps?
Are there sample data or pre-trained models available?
    If generating features_train.pth requires a specific model or dataset, could you provide the relevant resources or guidance?

Steps to Reproduce
Run the generate_cost_matrix.py script.
The script attempts to load the features_train.pth file, but the file does not exist or is not provided.

Expected Behavior
Provide detailed steps or a script to generate the features_train.pth file.
If possible, provide sample data or pre-trained models to facilitate reproduction.
Additional Information

I have already tried the following:
    Searched the repository for relevant scripts but could not find any code to generate features_train.pth.
    Checked the documentation but did not find any related instructions.

Thank you for your help! If there’s anything else I need to clarify, please let me know.
