的{{1}}进行读取，然后将图像从float32转换为uint8以接受然后，theCanny检测器cv2.imshow()使用了cv.IMREAD_LOAD_GDAL，此后我想显示/绘制图像，但是它显示了有关尺寸的错误，它显示：
图片数据的形状无效（4975、1、2）
cv2.Canny()显示的错误是：
cv2.houghlines()
问题是使用image = cv.imread(path,cv.IMREAD_LOAD_GDAL)
convert = np.uint8(image)
ed = cv.Canny(arr,50,200)
line = cv.houghlines(ed,1,np.pi / 180,240)
plt.imshow(line)
后，它将图像从2D更改为3D：（736，1109）'uint8'变为（4975，1，2）'float32'
