Full name of NNVM, TVM

I wonder the full name of NNVM, TVM?
Neural Network Vxxx Mxxx
and
Tensor Vxxx Mxxx

Does it mean “virtual machine”?

I guess so. See this post for details

NNVM (Neural Network Virtual Machine) for computation graphs and TVM (Tensor Virtual Machine) for tensor operators.

indeed, it does refer to virtual machine, in LLVM fashion
