Cannot use sklearn?

[zwdnet]

I install the sklearn lib using "pip3 install sklearn",then I import sklearn in the python3,there were many errors like this:
ImportError: cannot import name 'SemLock'
......
ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

I found that maybe we must mount /dev/shm first then install python.

Could you please solve this problem? Or dose the Aid Learning not support sklearn? Thank you!

because of the aid learning don't need root privileges...so it cannot support the command:
mount /dev/shm so the SemLock is not supported....
but in the aidlearning support sklearn for python2.7 now..but not sklearn for python3.6...in the next version ,I will added it....thank u for for the testing..
