关于json_to_dataset时出现 module ‘labelme.utils’ has no attribute ‘draw_label问题解决’
相信肯定很多朋友遇到过这种问题:
AttributeError: module ' labelme. utils' has no attribute ' draw label'
终端显示模块utils缺少属性draw_label.
其实呢,这个问题我弄了两天都没有解决,最后我决定放弃这个函数。
之后怎么办呢,相信出现这种问题时大家都是从别人博客里copy过json_to_dataset这个文件的代码的。既然别人的代码修改时避不开draw_label,我选择回到最开始。
直接修改label的json_to_dataset文件初始代码
你可能会说,以前的代码已经没了,不要紧,在终端卸掉labelme再重新安装就好了。
以下是我修改的代码:
import argparse
import base64
import json
import os
import os.path as osp
import imgviz
import PIL.Image
from labelme.logger import logger
from labelme import utils
import cv2
from math import *
import numpy as np
import random
def main():
list_path = os.listdir('F:/zkx') # 这是我的路径,替换成自己的就好
for i in range(0, len(list_path)):
logger.warning('This script is aimed to demonstrate how to convert the'
'JSON file to a single image dataset, and not to handle'
'multiple JSON files to generate a real-use dataset.')
parser = argparse.ArgumentParser()
parser.add_argument('--json_file')
parser.add_argument('-o', '--out', default=None)
args = parser.parse_args()
json_file = 'F:/zkx/' + list_path[i] # 这是我的路径,替换成自己的就好
print(list_path[i])
if args.out is None:
out_dir = osp.basename(json_file).replace('.', '_') # 返回文件名
out_dir = osp.join(osp.dirname(json_file), out_dir) # 把目录和文件名合成一个路径
else:
out_dir = args.out
if not osp.exists(out_dir):
os.mkdir(out_dir) # 用于以数字权限模式创建目录
data = json.load(open(json_file))
imageData = data.get('imageData')
if not imageData:
imagePath = os.path.join(os.path.dirname(json_file), data['imagePath']) # os.path.dirname返回文件路径
with open(imagePath, 'rb') as f:
imageData = f.read()
imageData = base64.b64encode(imageData).decode('utf-8')
img = utils.img_b64_to_arr(imageData)
label_name_to_value = {'_background_': 0}
for shape in sorted(data['shapes'], key=lambda x: x['label']):
label_name = shape['label']
if label_name in label_name_to_value:
label_value = label_name_to_value[label_name]
else:
label_value = len(label_name_to_value)
label_name_to_value[label_name] = label_value
lbl, _ = utils.shapes_to_label(
img.shape, data['shapes'], label_name_to_value
)
label_names = [None] * (max(label_name_to_value.values()) + 1)
for name, value in label_name_to_value.items():
label_names[value] = name
lbl_viz = imgviz.label2rgb(
label=lbl, img=imgviz.asgray(img), label_names=label_names, loc='rb'
)
PIL.Image.fromarray(img).save(osp.join(out_dir, 'img.png'))
utils.lblsave(osp.join(out_dir, 'label.png'), lbl)
PIL.Image.fromarray(lbl_viz).save(osp.join(out_dir, 'label_viz.png'))
with open(osp.join(out_dir, 'label_names.txt'), 'w') as f:
for lbl_name in label_names:
f.write(lbl_name + '\n')
logger.info('Saved to: {}'.format(out_dir))
x = out_dir+'\\label.png'
if __name__ == '__main__':
main()
执行的脚本,结果如下:
每个文件夹内包含的文件如下:
