Installed open3d lib but the library is not loading

Question

I am in the process of setting up my m1 pro max laptop. I have downloaded python, and I am installing all the required libs through pip. I am having problems installing open 3d lib.

When I run this:

import sys
print(sys.version)

import platform
print(platform.platform())

import numpy as np
import open3d as o3d


print("Load a ply point cloud, print it, and render it")
pcd = o3d.io.read_point_cloud("data/bun315.ply")
print(pcd)
print(np.asarray(pcd.points))
o3d.visualization.draw_geometries([pcd])

I get this error:

3.9.1 (v3.9.1:1e5d33e9b9, Dec  7 2020, 12:44:01)

I have searched up the error but nothing has worked. Not sure why its trying homebrew, I downloaded it to see try some things but ended up removing it from my laptop. When trying to install the open 3d lib I have had no issues with intel and m2 air laptop, but for some reason its not working on this laptop.

Answer 1

brew install libomp solves the problem.
