After using source /path/to/Open3D-ML/set_open3d_ml_root.sh I got this error when trying to test the integration of MyModel

@YoushaaMurhij @ismarintan98 I cannot reproduce this error, Could you let me know the output of following lines of code? I wonder if you have the latest version of Open3D installed.

import open3d as o3d
print(dir(o3d.ml.contrib))

[sanskar107]

This is fixed with the latest release.
