報錯如下：
Traceback (most recent call last):
File "E:/dell/Documents/PycharmProjects/color/search.py", line 31, in <module>
features = cd.describe(query)
File "E:\dell\Documents\PycharmProjects\color\pyimagesearch\colordescriptor.py", line 13, in describe
image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
cv2.error: OpenCV(4.1.0) C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'
到底如何改呢？
