Cannot have the model.py file after training my lstm model over sst2 datatset without adversarial training

[SkyWarrior123]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Run following command textattack ...
2. Run following code ...
3. See error

Expected behavior
There should be a module.py file generated after training lstm over sst2 dataset using the command below

textattack train --model lstm --dataset sst2 --epochs 20 --early-stopping-epochs 3

Screenshots or Traceback
While trying to attack my best_trained model using the command below

textattack attack --model-from-file ./outputs/2024-11-28-11-41-55-920215/best_model/model.py \
--dataset-from-huggingface sst2 \
--attack-recipe deepwordbug \
--log-to-txt results_deepwordbug.txt

System Information (please complete the following information):

• OS: MacOs
• Library versions (e.g. torch==1.7.0, transformers==3.3.0)
• Textattack version

Additional context
I am trying to reproduce the textattack paper's adversarial training figure the image is attached below

Can someone please help me to reproduce the above figure I would be very grateful to learn and understand why it is or not reproducible

Does the file at outputs/2024-11-28-11-41-55-920215/best_model/model.py exist? The screenshot you've shared shows best_model as a directory, and not a Python module.
