Failed to run train.py

[sgcts]

When I tried to run python train.py -s ~/workspace/tandt_db/tandt/truck, I meet two errors:

Optimizing

    return struct.unpack(endian_character + format_char_sequence, data)

During handling of the above exception, another exception occurred:

How to deal with it?

Train or truck? Do you convert both?

Train or truck? Do you convert both?

I trained the Train, but I have solved my problem. The reason is that my data have some problem because of the bad internet when I downloaded them, and I have re-downloaded those data. Thanks for your help.
