About python hmmlearn

Enter the code for this site from above and

X,Z=model.sample(10)

I ran .

>>>X
array([0.75706838, -0.1280334],
       [ 10.3137587 ,  10.59635189],
...

However, if you run it in your environment,

 [[10.72456536 10.72456536]
 [  0.79450025   0.79450025]
...

As shown in , the two values are the same.
Obviously, I think the results of the site's execution are correct, but why are the two values the same?

The python version is 3.6.5, and the hmmlearn version is 0.2.0.
If you know the cause, please reply.
