请问bert预训练模型是下载的哪个，我下载的 https://storage.googleapis.com/bert_models/2018_11_03/chinese_L-12_H-768_A-12.zip这个，checkpoint加载bert_model.ckpt.data-00000-of-00001文件，会报错

chinese_L-12_H-768_A-12/bert_model.ckpt.data-00000-of-00001: Data loss: not an sstable (bad magic number): perhaps your file is in a different file format and you need to use a different restore operator? 会报这个错
