Thank for your reply.
But when I run the model:
rlib = tvm.runtime.module.load_module(dso_path)
ctx = tvm.cpu()
rt_mod = graph_executor.GraphModule(rlib['default'](ctx))
The net is not use nuc_fpga_conv2d, I don’t see the nuc_fpga_conv2d() 's output “Calling From nuc_fpga_conv2d”,It still use nn.conv2d .
