Question

我正在尝试使用opencv渲染图像。

这是代码

from matplotlib import pyplot as plt
import cv2

img = cv2.imread('xwdsh.png')
plt.imshow(img)
plt.show()

这段代码在jupyter中运行良好，但在Python CLI模式下导致以下错误。

$ /Users/jay/anaconda3/envs/tf/bin/pythonw /afs/afs.sxl/cv.dl/face_detection_image.py
Traceback (most recent call last):
  File "/afs/afs.sxl/cv.dl/face_detection_image.py", line 5, in <module>
    plt.imshow(img)

    raise TypeError("Image data cannot be converted to float")
TypeError: Image data cannot be converted to float

用实际路径替换完整/路径，例如/afs/afs.sxl/cv.dl/xwdsh.png

img = cv2.imread('full/path/xwdsh.png')
plt.imshow(img)
plt.show()

python中的opencv错误：无法将图像数据转换为float
