Error: package or namespace load failed for ‘xgboost’:

[wilfriedguiblet]

Hello,

After installing Quadron and its libraries as described in the manual, I get the following message when running the software:

Error: package or namespace load failed for ‘xgboost’:
package ‘xgboost’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version

I am on MacOS 10.15 and my R version is 3.6.1.

How can I resolve this?

Thank you
