Colab run error

Hi, I really appreciate your work, and your tutorial video is clear and helpful! However, I had an issue running colab, the error message is as follows. Could anyone help me with it? Thanks a lot!

> /content/LLFF
Need to run COLMAP
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.

Start with imgs2poses.py and the traceback path llff/poses/colmap_wrapper.py, then reproduce the reported feature_extractor command in Colab. Trace why that command exits with the displayed X display error; done means the pose-generation run completes successfully without the reported failure.
