error when using reticulate in Rmarkdown

[HediaTnani]

Hi,

I'm having this error Error in py_call_impl(callable, dots$args, dots$keywords) : TypeError: use() got an unexpected keyword argument 'warn' when running this code in Rmarkdown

#Import packages
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
df = pd.read_table('../../data.txt',sep='\t',header=(0))
df.describe()

I'm running this chunk before:

library(reticulate)
use_python("/usr/bin/python")

How to solve this error message please?

This is an issue that should be fixed in the development version of reticulate -- can you try upgrading with:

remotes::install_github("rstudio/reticulate")

Hi,
I had the same issue and the upgrade with the development fixed it.
Thank you

Even though After installing the Latest version of Reticulate, the error still apperars

This most likely depends on the version of matplotlib that is installed. This is where we call use():

reticulate/R/knitr-engine.R

Lines 396 to 400 in e7a3111

	version <- numeric_version(matplotlib$`__version__`)
	if (version < "3.3.0")
	matplotlib$use("agg", warn = FALSE, force = TRUE)
	else
	matplotlib$use("agg", force = TRUE)

@BhuvaneshMurugan, what version of matplotlib do you have installed? Does updating to the latest version resolve things?

Hi @pvsundar the error message you're seeing is a little different, and likely unrelated to the original issue (which is fixed already). Can you please open a new issue, ideally with a minimal reproducible example that generates the error?
