Code snippet to visualise the position of the box

import matplotlib.image as img
import matplotlib.pyplot as plt
from datasets import load_dataset
from matplotlib.patches import Rectangle

# Load dataset
ds_name = "SaulLu/Caltech-101"
ds_config = "without_background_category"

ds_without = load_dataset(ds_name, ds_config, use_auth_token=True)

# Extract information for the sample we want to show
index = 100
sample = ds_without["train"][index]
box_coord = sample["annotation"]["box_coord"][0]
img_path = sample["image"].filename

# Create plot
# define Matplotlib figure and axis
fig, ax = plt.subplots()

# plot figure
image = img.imread(img_path)
ax.imshow(image)

# add rectangle to plot
ax.add_patch(
    Rectangle((box_coord[2], box_coord[0]), box_coord[3] - box_coord[2], box_coord[1] - box_coord[0], fill=None)
)

# display plot
plt.show()
