RISC-V has standardized a series of standard extensions beyond the integer base instructions which can be implemented or omitted as desired depending on the design goals (e.g. energy/area/performance/storage goals).

May be ml2cpp already generates code that a smart compiler can vectorize automatically with SIMD instructions. This is also true for all hardware architectures.
ml2cpp only generated source code, is not responsible of the environment this code will be compiled/used in. PERIOD.
ML2CPP can generate specific C++ code with RISC-V extensions allowing all scikit-learn, pytorch, caret ML models to be deployable natively on this platform.
RISC-V extensions have the advantage to be non-proprietary.
This is a place holder for following the recent efforts on designing RISC-V specific extensions for AI/ML.
No public hardware is available yet.
Sifive Intelligence X280 CPU is an interesting start point. https://www.sifive.com/blog/introduction-to-the-sifive-intelligence-x280
