UnsatisfiableError while installing open3d with conda

Question

I'm trying to install open3d into my conda environment. This is what I did:

conda create --name env python=3.9 -y
conda activate env
conda install -c open3d-admin open3d

But the last command fails with this output:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

Works with Conda Forge

Not documented, but seems like their packages are built with the conda-forge channel prioritized. So, instead try:

conda create -n env -c conda-forge -c open3d-admin python=3.9 open3d

or use YAML:

so-open3d.yaml

name: so-open3d
channels:
  - conda-forge
  - open3d-admin
  - nodefaults
dependencies:
  - python=3.9
  - open3d

with

conda env create -n env -f so-open3d.yaml
