When I use this code “
$LoadAddOns = {“FeynArts”};
«FeynCalc`”
the FeynHepers can not work.

When I use this code “
$LoadAddOns = {“FeynHepers”};
«FeynCalc`”
the FeynArts can not work.

“$LoadAddOns = {“FeynHepers”}” and “$LoadAddOns = {“FeynArts”}” can not work at the same time.

so, I want to know how can i use FeynArts and FeynHelpers at the same time.
