how to load checkpoint?
i download the model from bert, it only has model.ckpt.data，model.ckpt.meta and model.ckpt.index, i donnot which to load, what is checkpoint file for convert.py?
Converting TensorFlow checkpoint from ../dataset/bert/uncased_L-12_H-768_A-12/bert_model

I tried using the `export_checkpoint.py` file in ALBERT and sent that into the `convert_tf_checkpoint_to_pytorch` command and there was no error. However the resulting `pytorch.bin` output was unusable :\<|||||>@dan-hu-spring do you mind opening a new issue with your issue, so that we may take a look?
