ValueError when use det only / 单独执行检测时报错 ValueError
问题
使用 PaddleOCR 单独执行检测时，报错 ValueError
import numpy as np
from paddleocr import PaddleOCR
ppocr = PaddleOCR(lang='ch', use_angle_cls=False,)
image: np.ndarray = ...
results = ppocr.ocr(image, det=True, rec=False, cls=False)
print(results)
报错如下：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\ProgramData\conda\envs\gsds\Lib\site-packages\paddleocr\paddleocr.py", line 674, in ocr
if not dt_boxes:
^^^^^^^^
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
出错位置
其中，dt_boxes 数据示例
dt_boxes = np.array([[
[ 515., 4.],
[1127., 4.],
[1127., 41.],
[ 515., 41.]
]], dtype=np.float32)
print(f'{dt_boxes.all()=}')
print(f'{dt_boxes.any()=}')
dt_boxes.all()=True
dt_boxes.any()=True
临时解决方案
~if not dt_boxes: 改为 if not dt_boxes.all():~
更正：dt_boxes 为 None 时会报错
if not dt_boxes: 改为 if dt_boxes is None or not dt_boxes.all():

dygraph 分支好像也是有类似的问题
paddleocr --image_dir ./doc/imgs/11.jpg --use_angle_cls False --use_gpu false --det True --rec False
