code: def patch_transformers(log_incompatible=False):
      """
      Patches transformers version > 4.x to work with code that
      was written for version < 4.x. Specifically, before you
      could do something like `from transformers.modeling_bert import x`
      but this was moved to
      `from transformers.models.bert.modeling_bert import x`
      in newer versions. This functions fixes this discrepancy by adding
      these modules back to path.
  
      Another thing this function fixes is the conflict with local
      datasets folder vs huggingface datasets library in loading
      of transformers > 4.x version. To achieve this we modify sys.path
      to look for local folder at the last in path resolver. This is
      reverted back to original behavior at the end of the function.
