使用 Reticulate 从 R 导入 Python package（熊猫）

Question

Context: I was using Python on Atom IDE and installing/importing packages is working normally. Now I would like to work with Python on Rstudio through Reticulate package.

Problem: I'm not able to import Pandas on Rstudio even though a can Import numpy and math. The error is "ModuleNotFoundError: No module named 'pandas'".

i) Python 3.8.5 installed (32 bit) ii) pip3 21.1.2 installed iii) Reticulate 1.2.0 installed iv) Pandas is already installed (~\AppData\Local\Programs\Python\Python38-32\Lib\site-packages)

Answer 1

What does your code block look like for instantiating reticulate?

Here is mine; you should get into the habit of using environments as they will ensure all your packages are there and exactly the version you want.

# load python
library(reticulate)
use_python('C:/Users/Andrew/Anaconda3/')
use_condaenv(condaenv='my_ml', required=TRUE)
library(knitr)

Answer 2

You could have many Python environments.

Check reticulate::py_module_available("pandas") .

And, if neccesary, reticulate::py_install("pandas") .
