How to only load model weights for the evalaution script?

🤗Accelerate

from accelerate import Accelerator
import torch

accelerator = Accelerator(project_dir="my/save/path")

my_scheduler = torch.optim.lr_scheduler.StepLR(my_optimizer, step_size=1, gamma=0.99)
my_model, my_optimizer, my_training_dataloader = accelerator.prepare(my_model, my_optimizer, my_training_dataloader)

# Register the LR scheduler
accelerator.register_for_checkpointing(my_scheduler)

# Save the starting state
accelerator.save_state()

device = accelerator.device
my_model.to(device)

# Perform training
for epoch in range(num_epochs):
    for batch in my_training_dataloader:
        my_optimizer.zero_grad()
        inputs, targets = batch
        inputs = inputs.to(device)
        targets = targets.to(device)
        outputs = my_model(inputs)
        loss = my_loss_function(outputs, targets)
        accelerator.backward(loss)
        my_optimizer.step()
    my_scheduler.step()

# Restore previous state
accelerator.load_state("my/save/path/checkpointing/checkpoint_0")```

> If I need to just load the model weights in the evaluation script or load 
the weights in training framework which does not use accelerate, how can i do that?

Can anyone provide suggestions?
