Question

每当我运行底部文件时，我都会收到此错误。奇怪的是，当我通过终端运行它时，它运行良好。但是，当我通过基于Web的IDE运行它时，出现错误。


import cv2
import sys

num_down = 2       # number of downsampling steps
num_bilateral = 7  # number of bilateral filtering steps

img_rgb = cv2.imread(sys.argv[1])

# downsample image using Gaussian pyramid
# We use _ in range because we don't care about the actual index
img_color = img_rgb
for _ in range(num_down):
    img_color = cv2.pyrDown(img_color)

# repeatedly apply small bilateral filter instead of applying one large filter
for _ in range(num_bilateral):
    img_color = cv2.bilateralFilter(img_color, d=9, sigmaColor=9, sigmaSpace=7)

# upsample image to original size
for _ in range(num_down):
    img_color = cv2.pyrUp(img_color)

img_gray = cv2.cvtColor(img_rgb, cv2.COLOR_RGB2GRAY)
img_blur = cv2.medianBlur(img_gray, 7)

# detect and enhance edges
img_edge = cv2.adaptiveThreshold(img_blur, 255,
                                 cv2.ADAPTIVE_THRESH_MEAN_C,
                                 cv2.THRESH_BINARY,
                                 blockSize=9,
                                 C=2)


# convert back to color, bit-AND with color image
img_edge2 = cv2.cvtColor(img_edge, cv2.COLOR_GRAY2RGB)
img_cartoon = cv2.bitwise_and(img_color, img_edge2)

# save
cv2.imwrite(sys.argv[2], img_cartoon)

回溯（最近一次通话最近）：文件“ blur.py”，第36行，在 img_cartoon = cv2.bitwise_and（img_color，img_edge2）cv2.error：OpenCV（4.1.0）/io/opencv/modules/core/src/arithm.cpp:229：错误：（-209：输入参数的大小不匹配）操作都不是 'array op array'（其中数组具有相同的大小和类型），也不函数'binary_op'中的'array op scalar'或'scalar op array'

错误：（-209：输入参数的大小不匹配）
