Questions
#1

hello!

i’m fresh user of TVM.

I have a question after watching the tutorial below. https://docs.tvm.ai/tutorials/dev/low_level_custom_pass.html

when i using tvm.lower function to see lowered code before codegen to a specific target machine, i wonder how to map the lowered code to each layer.

for example

If I write the code above and use tvm.lower, the lowered code is shown below.

This code seems to have no name information associated with the topi.nn.conv2d layer. How does TVM map names from the lowered code to each network layer?

I want to modify only the conv2d layer using the add_lower_pass option like above tutorial. Do you have any examples related to this or solution??
