Hi all,
I'm trying to work with xact on Fedora release 33 but face with a problem:
The line of
Block[{Print}, << xAct`xTras`]
leads to hanging the Mathematica!
Also
<< xAct`xTras`
leads to
Package xAct`xPerm` version 1.2.3, {2015,8,23}
CopyRight (C) 2003-2020, Jose M. Martin-Garcia, under the General Public License.
Connecting to external linux executable...
Sometimes, I face with the following errors:
PermDeg::undef
xAct`xTensor`Dagger::unknown
Could someone please explain to me what the error comes from?
Many thanks and best wishes,
Alireza
