AttributeError: 'NoneType' object has no attribute 'block_index'

I'm very interested in this work of yours and am trying to run the code. But when the command PYTHONPATH="$PWD" python simlarity/zeroshot_reassembly.py is executed at the end, an error is always reported. The reason for my analysis was that I could not get the best model in the prescribed rounds, but I increased the number of trials to a larger value and still could not find the best model. I wonder how the author views this issue?
