读取 jpeg2000.cpp:104: error: (-213:The function/feature is not implemented) imgcodecs:

一、opencv 读取jpeg2000 图片使报错：

_jpeg2000.cpp:104: error: (-213:The function/feature is not implemented) imgcodecs: Jasper (JPEG-2000) codec is disabled. You can enable it via 'OPENCV_IO_ENABLE_JASPER' option

二、解决办法：

from os import environ
environ["OPENCV_IO_ENABLE_JASPER"] = "true"
import cv2 as cv

！！！ 如果实在不行，pip  uninstall opencv-python  后再重新安装下，再按照上述操作。 亲测可解决问题。
