【问题描述】：
我正在检查 LLFF 的 github 代码：https://github.com/Fyusion/LLFF，非刚性 NeRF：https://github.com/facebookresearch/nonrigid_nerf 并按照建议的步骤安装要求。在运行预处理文件时，该文件通过 SfM 使用 COLMAP 从图像返回姿势。在远程服务器中执行预处理时出现以下错误。谁能帮我解决这个问题？
python preprocess.py——输入数据/example_sequence1/
Need to run COLMAP
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, webgl, xcb.
