无法在 Python 中导入 shapely.geometry [英] Cannot import shapely.geometry in Python

问题描述

我正在尝试从 IPython 笔记本中的 shapely.geometry 导入多点.

I am trying to import Multipoint from shapely.geometry in IPython notebook.

当我执行from shapely.geometry import MultiPoint"时，出现错误No module named shapely.geometry".

When I do "from shapely.geometry import MultiPoint", I get the error "No module named shapely.geometry".

所以，我尝试执行!pip install --upgrade shapely"，为此我得到了错误

So, I tried doing "!pip install --upgrade shapely", for this I get the error

Running setup.py (path:/tmp/pip-build-NyZFjW/shapely/setup.py) egg_info for package shapely
Failed `CDLL(libgeos_c.so.1)`

我需要找到使用 DBSCAN 算法形成的每个集群的集群质心.只有解决了这个问题，才能做到这一点.

I need to find my cluster centroids of each cluster that's formed using DBSCAN Algorithm. That can be done only if this issue is resolved.

任何帮助将不胜感激.

推荐答案

我在您的输出中发现了这个 OSError:

I had this OSError that I found in your output:

Could not find library geos_c or load any of its variants ['libgeos_c.so.1', 'libgeos_c.so']

要解决我安装了 lib-geos 的问题，请运行:

To solve that I installed the lib-geos, by running:

$ sudo apt-get install libgeos-dev
