string= “machine learning”.split() doc_vector = model.infer_vector(string) out= model.docvecs.most_similar([doc_vector]) I’m not sure 100% since I’m using a more recent release, but I think that the issue is connected to the fact that the most_similar function is expecting a string mapped in the feature space and not the raw string. 2 solved Gensim example, TypeError:between str and … Read more
Writing into the heap beyond a valid malloc’ed location results in undefined behavior. It may or may not result in a seg fault. Depends on what is in the heap location and how it is used by the rest of the program. Your program may not fail at all. But it does corrupt the heap … Read more

The problem is indeed here. char instring[2]; Now let’s think about this line. gets(instring); Let’s say you type 10 and hit enter. What will go into instring is three bytes. 1 0 A terminating null. instring can only hold two bytes, but gets will shove (at least) three in anyway. That extra byte will overflow … Read more
You probably need to turn on warnings in your compiler. The function f returns a bool (not an int as declared) and does not do so unless the number of divisors of x is equal to two. This are fairly trivial mistakes that any decent C++ compiler should warn you about. Do not ignore warnings. … Read more
