RuntimeError: Missing key(s) in state_dict: "encoder.embeddings.position_ids"

Hi,

I'm trying to get results from the DPR reader, but when I run the following command, I get this error.

command:
python train_extractive_reader.py
prediction_results_file=/home/nnishika/dprout/dpr_reader_on_stqa_decomps.json
eval_top_docs=10
dev_files=/home/nnishika/dprout/dpr_on_stqa_decomps.json
model_file=/home/nnishika/DPR/dpr/downloads/checkpoint/reader/nq-single/hf-bert-base.cp
train.dev_batch_size=80
passages_per_question_predict=100
encoder.sequence_length=350

error:
RuntimeError: Missing key(s) in state_dict: "encoder.embeddings.position_ids"

My model file is a reader checkpoint, so I'm not sure why this is happening. I tried with with this command too using a provided dev file (instead of the one I made) if you want to try reproducing this error.

python3 train_extractive_reader.py
prediction_results_file=junk.out
eval_top_docs=10
dev_files=/home/nnishika/DPR/dpr/downloads/data/retriever_results/nq/single-adv-hn/test.json
model_file=/home/nnishika/DPR/dpr/downloads/checkpoint/reader/nq-single/hf-bert-base.cp
train.dev_batch_size=8
passages_per_question_predict=100
encoder.sequence_length=350

Let me know if you get this error on your end too.

Thank you
