How to Use the Model

import torch
import torchvision.models as models
import requests
from PIL import Image
from torchvision import transforms
import io
import torch.nn.functional as F

# Load the model architecture (Alexnet)
model = models.alexnet(weights=models.AlexNet_Weights.DEFAULT)
in_features = model.classifier[6].in_features
model.classifier[6] = nn.Linear(in_features, num_classes)

# Load the saved model weights

model_weights_path = './alexnet_jajanan_tradisional_classifier.pth'
model.load_state_dict(torch.load(model_weights_path))

# Put the model in evaluation mode
model.eval()

# URL of the image you want to classify
# image_url = 'https://thumbs.dreamstime.com/z/grontol-jagung-white-background-traditional-snacks-indonesia-boiled-shelled-corn-sprinkled-grated-coconut-176198473.jpg' # grontol

    img = Image.open(io.BytesIO(response.content))
 else:

class_to_label = {0: 'grontol', 1: 'lanting', 2: 'lumpia', 3: 'putu ayu', 4: 'serabi solo', 5: 'wajik'}

with torch.no_grad():

# Get the predicted class label
probabilities = F.softmax(output, dim=1)
# Get the predicted class and its confidence

# Print the predicted class
