Pytorch Model Exporting Issue: MLIR Verification Failed

[saienduri]

With the latest torch (2.4) and iree-turbine, we are seeing this MLIR verification failure come up for a lot of our models during the export stage (aot.export).

Instructions to reproduce this error:

Follow setup instructions here including the "Turbine Mode" instructions: https://github.com/nod-ai/SHARK-TestSuite/blob/main/e2eshark/README.md.

Then, run the following command from the SHARK-TestSuite/e2eshark directory (example to only run bert model). Change --tests flag based on the model you want to test:

HF_TOKEN=<your_hf_token> python3.11 ./run.py \
          -r ./test-turbine \
          --report \
          --cachedir ~/huggingface_cache \
          --mode turbine \
          -g models \
          --postprocess \
          -v \
          --tests pytorch/models/bert-large-uncased

You can find the debug artifacts in SHARK-TestSuite/e2eshark/test-turbine/pytorch/models/<model_name>
Here you can find the model-run.log file for example which will describe the error in more detail. You can also find the mlir generated for the model that failed verification in /tmp/turbine_module_builder_error.mlir

Is there any update on this? I also need help with this error.
