Julia 中 Tensors.jl 掉用 Vec 有个很奇怪的事情：

julia> using Tensors

julia> Vec{2}([1,3])
2-element Tensor{1,2,Int64,2}:
 1
 3

julia> Vec{2,Int}([1,3])
ERROR: MethodError: no method matching Tensor{1,2,Int64,2}(::Array{Int64,1})
Closest candidates are:
  Tensor{1,2,Int64,2}(::Tuple{Vararg{T,N}} where T where N) where {order, dim, T, M} at /Users/yczhang/.julia/packages/Tensors/EOKLk/src/Tensors.jl:65
  Tensor{1,2,Int64,2}(::Function) where {order, dim, T, M} at /Users/yczhang/.julia/packages/Tensors/EOKLk/src/Tensors.jl:66
Stacktrace:
