使用Anaconda安装OSMnx [英] Installing OSMnx with Anaconda

问题描述

我正在尝试按照此处概述的步骤在我的计算机上以Python 3安装osmnx软件包

I am trying to install the osmnx package in Python 3 on my computer, following the steps outlined here https://geoffboeing.com/2017/02/python-getting-started/. The steps are:

1. 下载miniconda，路径为C:\Anaconda.我正在使用大学计算机，因此无法执行此操作.但是，Anaconda已安装在这些计算机上，路径为C:\Program Files \Anaconda3.
2. 在Anaconda提示中，我尝试了conda update -n base conda.但是，这没有完成，因为我没有对目标环境具有写权限"(C:\Program Files \Anaconda3).
3. 假设conda是最新的，我忽略了此错误. conda config --prepend channels conda-forge运行良好.
4. conda create -n ox -c conda-forge osmnx jupyterlab和conda activate ox运行良好.在安装的Anaconda Navigator>环境> ox>中列出了OSMnx和jupyterlab.
5. 在牛环境中，我运行了jupyter lab，但这产生了以下错误.很抱歉给我这么大的报价，但我不知道该怎么解释:

1. Download miniconda, with the path C:\Anaconda. I am unable to do this as I am using university computers. However, Anaconda is already installed on those computers, with the path C:\Program Files \Anaconda3.
2. Within the Anaconda Prompt, I tried conda update -n base conda. However, this does not go through because I do not 'have write permission to the target environment' (C:\Program Files \Anaconda3).
3. I ignored this error, assuming conda was up to date. conda config --prepend channels conda-forge ran fine.
4. conda create -n ox -c conda-forge osmnx jupyterlab and conda activate ox ran fine. OSMnx and jupyterlab are listed in Anaconda Navigator>Environments>ox>installed.
5. In the ox environment, I ran jupyter lab, but this gave the following error. I'm sorry for this huge quote, but I don't know how to interpret any of this:

(ox) C:\Users\bm17652>jupyter lab

    raise NotImplementedError
NotImplementedError

当我尝试从Anaconda Navigator打开Jupyter Lab并运行import osmnx as ox时，出现错误没有名为'osmnx'的模块".

When I try to open Jupyter Lab from Anaconda Navigator and run import osmnx as ox, I get the error "No module named 'osmnx'".

在我看来，Jupyter Lab似乎安装不正确，或与osmnx的连接不正确. 发生这些错误是因为:

To me, it seems like Jupyter Lab is not installed properly, or does not have the proper connections with osmnx. Are these errors occurring because:

• 我没有更新conda吗?
• 我正在从与Anaconda所在的目录(C:\Program Files \Anaconda3)不同的目录(C:\Users\bm17652)中运行代码吗?
• 我应该将Anaconda下载到其他路径吗?

• I haven't updated conda?
• I am running the code from a different directory (C:\Users\bm17652) than where Anaconda is (C:\Program Files \Anaconda3)?
• Should I download Anaconda to another path?

推荐答案

我遇到了类似的问题.解决方案是创建一个为OSMnx指定的新的完整环境.可以使用

I ran into a similar problem. The solution is to create a new full environment specified for OSMnx. This can be done using

conda config --prepend channels conda-forge
conda create -n ox --strict-channel-priority osmnx

然后您必须使用以下方法激活该环境:

you then have to activate that environment using:

(base) C:\Users\User>conda activate ox

之后，您可以运行:

(ox) C:\Users\User>python
>>> import osmnx as ox
>>>

测试安装是否成功
