error running the the test_plane.py

[opalai]

I ran the 'tests/test_plane.py ' but got the following error:

>>> python tests/test_plane.py  
RPly: Unable to open file

You should move dataset folder to the same folder you run the tests. The error states that you cannot find the "caixa.ply" file.
Please, verify if you have the file from this folder

Hi,
I'm having the same issue. The file is in the same folder.

import open3d as o3d
print(o3d.__version__)  # '0.17.0'

cloud = o3d.io.read_point_cloud("aaa.ply")

[Open3D WARNING] Read PLY failed: unable to read file: aaa.ply RPly: Aborted by user
