AttributeError: module 'cv2' has no attribute 'show'

根据引用中的错误信息，"AttributeError: module 'cv2' has no attribute 'show'"，这个错误表明在cv2模块中没有名为'show'的属性。通常情况下，cv2模块提供了'show'函数来显示图像，但是在这个特定的环境中，这个函数可能不存在。

解决这个问题的方法是尝试安装不同版本的opencv-contrib-python-headless。根据引用中的建议，可以尝试安装版本为4.2.0.32的opencv-contrib-python-headless。可以使用以下命令来安装：

pip install opencv-contrib-python-headless==4.2.0.32

另外，还需要确保之前安装的opencv相关包已经被清除干净。你可以卸载之前的opencv相关包，然后再安装opencv-contrib-python-headless。

总结一下，解决"AttributeError: module 'cv2' has no attribute 'show'"的方法是：
1. 尝试安装不同版本的opencv-contrib-python-headless，例如4.2.0.32。
2. 确保之前安装的opencv相关包已经被清除干净。
3. 安装完新的opencv-contrib-python-headless后，重新运行代码，看是否能够解决问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
