輸出數組img的佈局與cv :: Mat不兼容（步驟[ndims-1]！= elemsize或步驟[1]！= elemsize * nchannels）

Question

我得到這個錯誤： 輸出數組img的佈局是與CV ::墊（！步驟[爲ndims-1] =可達elemsize或步驟[1] =可達elemsize * nchannels）不相容 運行下面的代碼時：

I1 = cv2.imread('library1.jpg'); 
I2 = cv2.imread('library2.jpg'); 
# Load matching points 
matches = np.loadtxt('library_matches.txt'); 
img = np.hstack((I1, I2)) 
# Plot corresponding points 
radius = 2 
thickness = 2 
for m in matches: 
    # draw the keypoints 
    pt1 = (int(m[0]), int(m[1])) 
    pt2 = (int(m[2] + I1.shape[1]), int(m[3])) 
    lineColor = cv2.cv.CV_RGB(255, 0, 0) 
    ptColor = cv2.cv.CV_RGB(0, 255, 0) 
    cv2.circle(img, pt1, radius, ptColor, thickness) 
    cv2.line(img, pt1, pt2, lineColor, thickness) 
    cv2.circle(img, pt2, radius, ptColor, thickness) 
cv2.imshow("Matches", img) 

該代碼可用於兩個獲得相應的特徵來自不同視圖的類似圖像。 請幫忙嗎？

改變這一行：

img = np.hstack((I1, I2))

到：

img = np.array(np.hstack((I1, I2)))
