我曾尝试克隆coco API以从coco数据集中下载特定的类，但当我在Google Colaboratory中运行代码时，它给出了这个错误：name 'coco' is not defined。
!git clone https://github.com/philferriere/cocoapi
#display COCO categories
cats = coco.loadCats(coco.getCatIds())
nms=[cat['name'] for cat in cats]
print('COCO categories: \n{}\n'.format(' '.join(nms)))
# get all images containing given categories (I'm selecting the "bird")
catIds = coco.getCatIds(catNms=['bird']);
imgIds = coco.getImgIds(catIds=catIds);回答 1

我认为这来自于https://github.com/philferriere/cocoapi/blob/master/PythonAPI/demos/pycocoDemo.ipynb中的示例
并且您需要复制更多的行：
from pycocotools.coco import COCO
# ... skipped some lines here
# initialize COCO api for instance annotations
coco=COCO(annFile)
cats = coco.loadCats(coco.getCatIds())
nms=[cat['name'] for cat in cats]
print('COCO categories: \n{}\n'.format(' '.join(nms)))
# get all images containing given categories (I'm selecting the "bird")
catIds = coco.getCatIds(catNms=['bird']);
imgIds = coco.getImgIds(catIds=catIds);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
