joblib backend问题

Preprocess transition probs... [Parallel(n_jobs=30)]: Using backend MultiprocessingBackend with 30 concurrent workers. multiprocessing.pool.RemoteTraceback: """ Traceback (most recent call last): File "/home/ubuntu/anaconda3/lib/python3.7/multiprocessing/pool.py", line 121, in worker result = (True, func(*args, *kwds)) File "/home/ubuntu/anaconda3/lib/python3.7/site-packages/joblib/_parallel_backends.py", line 567, in call return self.func(args, **kwargs) File "/home/ubuntu/anaconda3/lib/python3.7/site-packages/joblib/parallel.py", line 225, in call for func, args, kwargs in self.items] File "/home/ubuntu/anaconda3/lib/python3.7/site-packages/joblib/parallel.py", line 225, in for func, args, kwargs in self.items] File "/home/ubuntu/anaconda3/lib/python3.7/site-packages/ge/walker.py", line 88, in _simulate_walks walk_length=walk_length, start_node=v)) File "/home/ubuntu/anaconda3/lib/python3.7/site-packages/ge/walker.py", line 56, in node2vec_walk next_node = cur_nbrs[alias_sample(alias_edges[edge][0], KeyError: (9836, 7324) """

The above exception was the direct cause of the following exception:

我是下载之后把joblib的backend改成multiprocessing，但其实不管是默认的还是其他的，都会报错说keyerror是random一个数据点。我用的是http://socialcomputing.asu.edu/datasets/BlogCatalog3 这个数据集，不管是stru2vec还是node2vec都会遇到这样问题。请教

2. TypeError: unsupported operand type(s) for +: 'int' and 'str' 在stru2vec中会遇到gensim报这个问题（同样的数据），也请教一下

那里有个print函数，把这个int值换成str（）就行了eg：int i =5， print('值：'+str(i)) 话说key error这个，请问您解决了么，我也有这个问题。

同样的问题，请问解决了吗

KeyError问题+1，不过提示稍微有一点不同

I was able to fix this, it was happening for non-directed graphs. Pull request here: https://github.com/shenweichen/GraphEmbedding/pull/40
