Hi, when i am running code, something was wrong:
File "E:/Code/TriDNR/TriDNR-master/demo1.py", line 37, in main
raw_walks, netwalks = net.getdeepwalks(directory, number_walks=20, walk_length=8)

File "E:\Code\TriDNR\TriDNR-master\networkutils.py", line 94, in getdeepwalks
G = graph.load_adjacencylist(dir+'/adjedges.txt')

File "C:\Users\darling\Anaconda3\lib\site-packages\deepwalk\graph.py", line 224, in load_adjacencylist
total = 0

File "C:\Users\darling\Anaconda3\lib\concurrent\futures\process.py", line 366, in _chain_from_iterable_of_lists
for element in iterable:

File "C:\Users\darling\Anaconda3\lib\concurrent\futures_base.py", line 586, in result_iterator
yield fs.pop().result()

File "C:\Users\darling\Anaconda3\lib\concurrent\futures_base.py", line 432, in result
return self.__get_result()

File "C:\Users\darling\Anaconda3\lib\concurrent\futures_base.py", line 384, in __get_result
raise self._exception

BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending.

I can't find reason about this, So can you help me?
