Creating a GUI for Point Cloud visualisation

[khablt96]

It doesn't like this.

Error:
PCD has no fields

And it reports this info about the point clouds.

Error:
Invoked with: [[PointCloud with 1771 points., PointCloud with 9311 points., PointCloud with 3400 points., PointCloud with 0 points., PointCloud with 307200 points.]

So maybe it doesn't run because this doesn't have any points.

my_img4= o3d.io.read_point_cloud("u.pcd")

Thanks , i remove the u.pcd, the PCD Error Message is disappeared. but the other Error still there
