python opencv 无法读取文件, 在cv2.imshow() 函数报错
cv2.error: OpenCV(3.4.1) C:\Miniconda3\conda-bld\opencv-suite_1533128839831\work\modules\highgui\src\window.cpp:356: error: (-215) size.width>0 && size.height>0 in function cv::imshow
解决 检查路径是否有错,如果有路径有 \ (特别是windows) 可以考虑在括号后引用路径“”前加入r,cv2.imread(r"xxx:\xxx\xxx\xxx.xxx") r后的字符串不转义\ 。或者 路径有中文。
# Name Version Build Channel

opencv 3.4.1 py37h6fd60c2_3 defaults
py-opencv 3.4.1 py37h1b0d24d_3 defaults
3.4.1 版本 还不支持中文也是 @#¥%&*( PIL skimage 等库也是可以考虑替代cv2
启动pyhon报错

在用户根目录,windows在C:\Users\xxx 下,有个.python_history 文件,可用记事本打开 使一些历史, 删除这个文件,就没有报错了
