node matching error while using NNCF with Transformers-LT (fairseq)

[sharathns93]

Seeing a node matching error (logs attached) while using NNCF with a Transformer model based on the fairseq implementation:
error_logs_nncf.txt

Steps to replicate the issue:

1. git clone https://github.com/mit-han-lab/hardware-aware-transformers.git

2. cd hardware-aware-transformers

3. pip install --editable .

4. pip install -U torch==1.9.1

5. pip install nncf

6. bash configs/wmt14.en-de/get_preprocessed.sh

7. git apply nncf_diff.txt
   (nncf_diff.txt)

8. python train.py --configs=configs/wmt14.en-de/subtransformer/HAT_wmt14ende_raspberrypi@3.5s_bleu@25.8.yml --sub-configs=configs/wmt14.en-de/subtransformer/common.yml --validate-subtransformer --cpu

Could reproduce the original issue and it seems to be fixed in #1600. However, after that I experience another failure:

@vshampor , is it still valid? If yes, any idea about the second failure?

[vshampor]

Still reproduces as of today with the second failure, investigating.
