python-Levenshtein AttributeError: module 'Levenshtein' has no attribute 'distance'

python-Levenshtein AttributeError: module 'Levenshtein' has no attribute 'distance'

今天咋运行程序的时候，出现了下面的错误：

[1/1000][15050/15056] Loss = 85.33192443847656[1/1000][15051/15056] Loss = 85.493408203125[1/1000][15052/15056] Loss = 78.12874603271484[1/1000][15053/15056] Loss = 86.8485107421875[1/1000][15054/15056] Loss = 81.8629150390625[1/1000][15055/15056] Loss = 136.6531219482422decoding0it [00:01, ?it/s]Traceback (most recent call last): File "train.py", line 117, in train(model) File "train.py", line 70, in train cer = eval(model, dev_dataloader) File "train.py", line 103, in eval cer += decoder.cer(trans, ref) / float(len(ref)) File "/home/eric/Documents/SpeechRecognition_MASR/decoder.py", line 58, in cer return Lev.distance(s1, s2)AttributeError: module 'Levenshtein' has no attribute 'distance'

然后发现自己已经装了Levenshtein。

解决方法

pip install python-Levenshtein==0.11.2

我原来的版本是0.12，降了一下版本，然后就不报错了。

测试代码为：

import Levenshtein as levlev.distance('Levenshtein', 'Lenvinsten')

如果正常输出为4的话，说明是正常的。
