Hi, I am using the Pynq Z2 board with the latest image (v3.0.1) and trying to follow the VTA setup: https://tvm.apache.org/docs/topic/vta/install.html
I am using the latest TVM release v0.15.0 on PYNQ-Z2 side and release v0.14.0 on PC (Linux Ubuntu 22.04)
The build process completed successfully but the Test program after running the following step is throwing error (Logs below the following 2 lines). I ran:
On Pynq: sudo ./apps/vta_rpc/start_rpc_server.sh
On PC: python MTP2/tvm/vta/tests/python/pynq/test_program_rpc.py
The logs are as below
On Pynq Z2:
xilinx@pynq:~/tvm$ sudo ./apps/vta_rpc/start_rpc_server.sh # pw is 'xilinx'
