使用 conda 安装 open3d 时出现 UnsatisfiableError

Question

我正在尝试将 open3d 安装到我的 conda 环境中。这就是我所做的：

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

但是最后一个命令失败并显示以下输出：

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.

Answer 1

与 Conda Forge 合作

没有记录，但似乎他们的软件包是按照优先顺序构建的

conda-forge

通道。所以，请尝试：

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

或使用 YAML：

so-open3d.yaml

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

与

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

Answer 2

我也有同样的问题。我按照merv的回答做了，结果成功了。至少，直到我在 Python 中导入 open3d 之前，我都会收到此错误：“[警告]自 Open3D 0.15 起，不推荐通过 conda 安装 Open3D。请通过以下方式重新安装 Open3D：

pip install open3d -U

。”

Open3D 似乎不应该与 conda 一起安装。
