“conda install -c open3d-admin open3d” → not found

[cwreynolds]

I want to use Open3D from Python. I've never touched Open3D, I know a bit of Python, my experience with Anaconda is “used it once, got it working, never touched it again.” I found https://anaconda.org/open3d-admin/open3d which suggestes: conda install -c open3d-admin open3d. On my macOS 12.6.3 M1 laptop, I did:

conda create -n open3d_2023 python=3.10
conda activate open3d_2023
conda install -c open3d-admin open3d

The install got “not found” while mentioning that current channels include https://conda.anaconda.org/open3d-admin/osx-arm64

How should I proceed? The Open3D instructions on GitHub suggest pip install open3d. I do not understand the interaction between conda and the older(?)/underlying(?) pip. Can I just run the pip command while the conda environment is active?

Hoping that the virtual environment would contain any fallout, I decided to just try it. The pip worked, but the installation test code snippet (from https://github.com/isl-org/Open3D) failed.

pip install open3d

WOT!? Nevermind, problem solved. Sorry for the “talking to myself” posts. Taking a moment to read the error above, realizing that it was looking for something called libomp, looked it up, did a:

brew install libomp

Then everything Just Worked. Was able to run all three suggested tests: Verify installation, Python API, and Open3D CLI.

Thanks for Open3D. It looks amazing!

as of now, the last version of open3d-admin open3d on any x64 system is 0.15.1,
and it depends on python 3.8.

I was unable to find conda package of later versions, that able to be installed on python 3.10,
so I am not sure how you manage it.

I am trying to use open3d in linux. I don't think, python-3.10 is compatible with open3d deps. So, I did this and it worked fine,

conda create -n open3d_env python=3.8
conda activate open3d_env
conda install -c open3d-admin open3d

Also, ensure that the open3d-admin channel is correctly configured in your Conda channels,

conda config --show channels
conda config --add channels open3d-admin
