The Handle is invalid error using source_python() from R Reticulate package

I've saved two files in the same folder. One is an R Script containing the reticulate function source_python(), the other file is the Python Script I want to source.

When I run the R script I get an error message which can be specifically attributed to import bcpandas. If I comment this line out - then it sources pandas, glob, os, pyodbc, numpy, subprocess just fine.

From what I've read - it could be that this is a problem with where my packages are saved. I used the default destination for saving my python packages when downloading using the function py_install(“bcpandas”)


I used the same function, without arguments this morning to download numpy py_install(“numpy”) - I've checked and numpy sits in this folder, alongside bcpandas.

Any ideas where I could be going wrong or what I could investigate next to try and solve the issue?

Thanks in advance :slight_smile:
