Can't convert the np.ndarray of type numpy.obi

my code is as follows"import xml.etree.ElementTree as ET
from pathlib import Path
from collections import defaultdict
from fastai.vision.all import *
import numpy as np
import torch
from yolov5 import YOLOv5

Define the paths to the dataset and annotations

dataset_path = Path(‘C:/Users/nirma/OneDrive/Documents/studies/CarbonArray’)
images_path = dataset_path / ‘Images’
annotations_path = dataset_path / ‘Annotations’

Function to get annotations

def get_annotations(image_path, annotations_path):
try:
annotation_file = annotations_path / (image_path.stem + ‘.xml’)
tree = ET.parse(annotation_file)
root = tree.getroot()

    bboxes = []
    labels = []
    
    for obj in root.findall('object'):
        bbox = obj.find('bndbox')
        bndbox = [float(bbox.find(tag).text) for tag in ['xmin', 'ymin', 'xmax', 'ymax']]
        label = obj.find('name').text  # Ensure that this matches the actual tag in your XML files
        bboxes.append(bndbox)
        labels.append(label)

    # Convert to numpy arrays with explicit types
    if len(bboxes) > 0:
        bboxes = np.array(bboxes, dtype=np.float32)
    else:
        bboxes = np.zeros((0, 4), dtype=np.float32)

    if len(labels) > 0:
        labels = np.array(labels, dtype=str)
    else:
        labels = np.array([], dtype=str)

    print(f"Image: {image_path}")
    print(f"Bounding boxes: {bboxes} (type: {bboxes.dtype})")
    print(f"Labels: {labels} (type: {labels.dtype})")

    return bboxes, labels
except Exception as e:
    print(f"Error parsing annotations for {image_path}: {e}")
    return np.zeros((0, 4), dtype=np.float32), np.array([], dtype=str)

Function to classify tree size based on pixel count

def get_tree_size_from_bbox(bbox):
width = bbox[2] - bbox[0]
height = bbox[3] - bbox[1]
area = width * height
if area < 1000:
return ‘small’
elif area < 5000:
return ‘medium’
else:
return ‘big’

Verify paths

print(f"Images path: {images_path}“)
print(f"Annotations path: {annotations_path}”)
print(f"Image files: {list(images_path.glob(‘*’))}")

Load your dataset using Fastai

def get_y(o):
bboxes, labels = get_annotations(o, annotations_path)
print(f"Annotations for {o}: bboxes={bboxes}, labels={labels}")
return bboxes, labels

Convert bounding boxes and labels to appropriate types within the DataBlock definition

def bbox_label_transform(o):
bboxes, labels = get_y(o)
print(f"Before conversion - Bounding boxes: {bboxes} (type: {type(bboxes)})“)
print(f"Before conversion - Labels: {labels} (type: {type(labels)})”)

bboxes = np.array(bboxes, dtype=np.float32)
labels = np.array(labels, dtype=str)

print(f"After conversion - Bounding boxes: {bboxes} (type: {bboxes.dtype})")
print(f"After conversion - Labels: {labels} (type: {labels.dtype})")

return bboxes, labels

Debug: Print the structure and types of the transformed data

def debug_transformed_data(o):
bboxes, labels = bbox_label_transform(o)
print(f"Transformed Bounding boxes: {bboxes} (type: {bboxes.dtype})“)
print(f"Transformed Labels: {labels} (type: {labels.dtype})”)
