[R-pkg-devel] How to solve this error while running python script in R environment?

When I am creating the R package based on the python script, I am getting the below error while checking the package.


* checking examples ... [60s] ERROR
Running examples in 'transformerForecasting-Ex.R' failed
The error most likely occurred in:

base::assign(".ptime", proc.time(), pos = "CheckExEnv")
### Name: TRANSFORMER
### Title: Transformer Model for Time Series Forecasting
### Aliases: TRANSFORMER

### ** Examples

data(S_P_500_Close_data)
df <- S_P_500_Close_data
result <- TRANSFORMER(df = S_P_500_Close_data, study_variable = "Price")
