Hi guys,
Has anyone tried to run python chunk codes inside a flexdashboard framework?
I keep getting this error "TypeError: float() argument must be a string or a number, not 'list'"
For example, the first chunk in R get some input
dateInput("startdate_r", "Start Date:", value = "2019-02-29")
dateInput("enddate_r", "End Date:", value = "2019-04-29")
and the second chunk in python tries to read it
#Something like that
print("hello")
Hi,
do you have a real minimal reprex you tried ?
It would help see what you are trying to do.
To interface R and python, you should look at
And how it works with Rmarkdown
https://rstudio.github.io/reticulate/articles/r_markdown.html
From your small piece of code, I understand you are trying to use flexdashboad with Shiny, right ?
This could be a little difference I guess - hence an important precision.
Yes, I am basically trying to use the flexdashboard with shiny to create a simple interactive dashboard using all the exploratory analysis and modeling that I have done in Python. As I stated above, flexdashboard with shiny currently does not support any python code inside the markdown template however if you were to switch the template from flexdashboard to an html_document format, it would work. I was wondering if there was a way around that.

title: "Test"
runtime: shiny
output:
flexdashboard::flex_dashboard:
orientation: columns
vertical_layout: fill

```{r setup, include=FALSE}
library(flexdashboard)
library(reticulate)
library(dplyr)
library(shiny)
library(shinydashboard)
library(reticulate)
```
```{r}
dateInput("startdate_r", "Start Date:", value = "2012-02-29")
dateInput("enddate_r", "End Date:", value = "2012-04-29")
```
Column
-------
```{python}
print("hello")
```
Thanks for the reproductible example. I can reproduce the error. For now I don't know where it comes from but there is indeed something going on...
There is an open issue related to your problem I think
@lyansaud can you specify your OS and you Python version ?
