Kai,
Just FYI, this is mainly an R mailing list and although there ware ways to
combine python with R (or sort of alone) within environments like RSTUDIO, this
may not be an optimal place to discuss this. You are discussing what is no
longer really "R markdown" and more just plain "markdown" that supports many
languages in many environments and you are using one called flexdashboard.
I had a similar problem for a while because I had an amazing number of copies
of python installed on my machine in various ways including directly and within
Anaconda and several other ways. Each may have kept copies of modules like
numpy in a different place. Unfortunately, when running python from RSTUDIO, it
was looking in a place that did not have it and when I used "pip" to get the
latest copy, it insisted I already had it!
So I eventually uninstalled all versions I could find and reinstalled just one
version and then got the numpy and pandas modules installed under that version.
Oh, I also replaced/updated RSTUDIO. Things work fine for now.
Some people may advise you on how to determine which version of python you are
calling, or change it, and how to download numpy to the place it is expected,
or change some environmental variable to point to it or any number of other
solutions. Some like virtual environments, for example.
The bottom line is your setup does not have numpy installed as far as the
software is concerned even if it is installed somewhere on your machine. When
you get things aligned, you will be fine.

Subject: [R] Problem to run python code in r markdown
Hi Team,I'm trying to run python in R markdown (flexdashboard). The code is
below:
try Python=============
```{r, include=FALSE, echo=TRUE}library(reticulate)py_install("numpy")
use_condaenv("base")
```
```{python}import numpy as np```
I got error message below:
Error in py_call_impl(callable, dots$args, dots$keywords) :
ModuleNotFoundError: No module named 'numpy'Calls: <Anonymous> ...
py_capture_output -> force -> <Anonymous> -> py_call_implIn addition: There
were 26 warnings (use warnings() to see them)Execution halted
Based on message, the python can not find numpy package. But I'm sure I
installed the package. I don't know how to fix the problem. please help Thank
you,Kai
