VTA simulation example AssertionError Error

I export path following the VTA installation instruction and run " python <tvm root>/vta/tests/python/integration/test_benchmark_topi_conv2d.py" to make a test. However, I received an error as:

Traceback (most recent call last):

It seems that I dont have the libvta_fsim file.
Can anyone help?
Thanks!

It appears that the simulation library wasn’t built properly. Does your config.cmake have set(USE_VTA_FSIM ON)? And once you built TVM, can you find under build the libvta_fsim.dylib/so file?

Was this issue ever resolved? I’m running into the same problem during my installation.
