creates a fx graph of the buffers generated by lowering
with this patch you can run e.g.
python benchmarks/torchbench.py --training --devices=cuda --inductor-dump --isolate -k hf_Bertto dump the forward and backward graphs of compute-buffers of hf_Bert. The resulting svg file will be in torchbenchmark/.
If you want to run it for other graphs, change the model_name in compile_fx so the dumped file matches the model name.
Also the dumping is quite slow, so for large models like hf_Bert, you would want to change the number of layers to a small number.
