[VTA]VTA simulator install

Hello everyone, I am a newbie to learn TVM, and I am installing VTA according to the tutorial recently. Since I don’t have PYNQ on hand, I decided to install the VTA simulator first. When running the 2D convolution program test_benchmark_topi_conv2d.py, an error is reported: ImportError: cannot import name’program_fpga’ from’vta’ (unknown location). So ,what’s the problem and how to fix it ?

Did u manage to get a work-around for this one?
