… named data map Pull Request resolved: #9153 We serialize tensors into the named data map, and return the output in preprocess result. Allowing for XNNPACK to share tensors with the same name (instead of duplicating). A key change here is with fused tensors. For BN and Convolution Fusion, we fuse the conv weights and bias with the BN parameters creating new tensors. We then create get_attr nodes for these new parameters. Due to the graph.fx interpreter in export pass base, the new names we create for these new tensors are lost each time. As a result, at the end we introduce a new pass to preserve the names we created. This seems a little hacky for now, but is the only way to preserve the new fused names.
