无法在R中导入 pandas [英] Not able to import pandas in R

问题描述

我从R/shiny调用一个python脚本为:

I am calling a python script from R/shiny as:

system("python /Users/Downloads/Untitled3.py EMEA regulatory '10% productivity saves SOW'")

它不能导入熊猫.

但是当我从终端直接调用脚本时:

But when I straight call the script from the terminal as:

python /Users/Downloads/Untitled3.py EMEA regulatory '10% productivity saves SOW'

它能够导入熊猫.我猜python中有一些版本问题.我安装了蟒蛇.谁能帮助我纠正问题.

It is able to import pandas. I guess some version issue in python.I have anaconda installed. Can anyone of you please help me in rectifying the issue.

尽管不是必需的，但脚本的起始位置为:

Although not required as, script starts as:

import pandas as pd 
import numpy as np
import sys

from difflib import SequenceMatcher
##### More code#########

推荐答案

问题

您拥有默认的系统python，然后还有anaconda发行版.

You have the default system python and then the anaconda distribution as well.

仅运行从R运行的命令将调用默认系统python，该系统没有必需的软件包.

Merely running the command that you are running from R calls the default system python that doesn't have the required packages.

修复

假设您在/Users/<username>/anaconda/bin/python(这是默认的Mac安装文件夹)中安装了anaconda，

Assuming you have anaconda installed at /Users/<username>/anaconda/bin/python (that's the default mac installation folder),

您应运行的R命令是​​-

the R command that you should run is -

system("/Users/<username>/anaconda/bin/python /Users/Downloads/Untitled3.py EMEA regulatory '10% productivity saves SOW'")

这可确保您明确使用anaconda的python二进制文件，这些文件将在pandas和安装在其中的其他相关库中使用.

This ensures that you are explicitly using anaconda's python binaries which will pick up on the pandas and other relevant libraries installed there.
