arma::fill:value

[MattJean]

" ‘value’ is not a member of ‘arma::fill’; did you mean ‘nlohmann::detail::parse_event_t::value’?
97 | prod[to]=arma::Mat(1,1, arma::fill::value(value));
| ^~~~~"

I would replace line 97 of tensor_tree.h by something like

"
prod[to] = arma::Mat(1, 1);
prod[to](0, 0) = value;
"

since arma::fill::value is not valid in some versions
