According to the issue I specified above and my experience, I think it is unclear about how to create a Relay module. For example, the tutorial uses a simple API to get the Relay module:
mod, params = relay.testing.resnet.get_workload(num_layers=n_layer, batch_size=batch_size, dtype=dtype)
On the other hand, if users want to build their own network, they may need to write the code like follows:
out1 = relay.nn.conv2d(...)
out2 = relay.nn.dense(out1, ...)
mod = relay.Module.from_expr(out2)
mod = relay.transform.InferType()(mod)
Note that this may not the only way to create a module, so I would suggest having a tutorial about this part. It may not necessary to be in the Relay with AutoTVM tutorial since this tutorial is supposed to focus on tuning. Maybe we could add it here or even make a new one talking about how to build a Relay module from scratch and make a reference link?
