file is too short to be an sstable

[eliaaaa]

Dear author, I made slight changes to your code to adapt to Python3 and TensorFlow2. But I encountered this issue when I run the CUB experiment:
"./replicate_results_iclr19.sh CUB 1 1 "
I have attached the error log for your reference. Could you please help me with that?

Traceback (most recent call last):

During handling of the above exception, another exception occurred:
