How to run the demo code?

[CopyNinja1999]

Hi, I've downloaded the code and pretrained file as instructed in my Win10 system. My files under the path looks like:
data/ LICENSE pair-bert-train_wiki-val_wiki-5-1.pth.tar pretrain/ readme.md fewshot_re_kit/ models/ paper/ pretrain.tar train_demo.py
But when I am running the given demo command, it gives me such error:
`$ python train_demo.py --trainN 5 --N 5 --K 1 --Q 1 --model pair --encoder bert --pair --hidden_size 768 --val_step 1000 --batch_size 4 --fp16
5-way-1-shot Few-Shot Relation Classification
model: pair
encoder: bert
max_length: 128
Some weights of the model checkpoint at bert-base-uncased were not used when initializing BertForSequenceClassification: ['cls.predictions.transform.dense.weight', 'cls.seq_relationship.bias', 'cls.predictions.bias', 'cls.predictions.transform.LayerNorm.bias', 'cls.predictions.decoder.weight', 'cls.predictions.transform.dense.bias', 'cls.predictions.transform.LayerNorm.weight', 'cls.seq_relationship.weight']

• This IS expected if you are initializing BertForSequenceClassification from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
• This IS NOT expected if you are initializing BertForSequenceClassification from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).
  Some weights of BertForSequenceClassification were not initialized from the model checkpoint at bert-base-uncased and are newly initialized: ['classifier.bias', 'classifier.weight']
  You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.

  AssertionError`
  What should I do to avoid the error?

Use vals instead of tests:
copy val_.json to test_.json
