Hi,

the conversion script for ConvBERT throws the following error message when using it:

Traceback (most recent call last):
  File "convert_convbert_original_tf1_checkpoint_to_pytorch.py", line 19, in <module>
    from ...utils import logging
ImportError: attempted relative import with no known parent package

I fixed that error, as well as using the correct name for the configuration file argument.

Additionally, I just found that the configuration files from the YituTech organization for ConvBERT from aren't correct, because they use:

"model_type": "conv_bert",

instead of:

"model_type": "convbert",

(This currently results in a KeyError: 'conv_bert' error).
