Hi, do any one use tensorflow lite on risc-v platform?
I use both python tflite_runtime and c++ tensorflow lite environment on risc-v platform to do image detecting, however it shows that the performance is really bad.
as the table shows below, I use default param to do benchmark(tensorflow-r2.5\tensorflow\lite\tools\benchmark)

in order to find whether software matters more to the result, I also compare the coremark scores on U540 and Raspberry 3B， it turns that coremark score gap is not that big as inference benchmark time(both cpu freq 1GHz).
