Keyerror \\'details' while importing arulespy

Hi!

I have successfully installed this library, but, when I try to import it in jupyter notebook inside visual studio code environment, I get the following error:

KeyError: '\details'

When I look for the error message, it redirects me to the init.py file.

I have successfully installed arules and arulesViz library in my Python and R environments.

Could someone see if I have omitted something? Maybe it is related to jupyter notebook?

Thanks in advance!!

Hmmm. Looks like there is some problem with the documentation system in rpy2. It seems like the R manual page in ruleExporer() has no details section which results in the issue. I will work on fixing this.

A little research shows that this issue was fixed in rpy2 Release 3.5.3 (see https://rpy2.github.io/doc/latest/html/changes.html). Please update to the latest version or rpy2.

The latest version of arulespy enforces now the correct version of rpy2.
