[Bug Fix] fix csViewer crashes with pyqt 1.15+

[simonwu53]

Description

When I tried to run the viewer for the dataset, the script immediately crashed when loading any image after selecting the city and annotation type. So I posted this update in case others also want to run the visualizer.

Command

CITYSCAPES_DATASET=/Volumes/Storage/Datasets/Cityscapes csViewer
