how to use hailopython ?

Hi there. I met a bug when I followed the tutorial to use hailopython. How can I solve this problem ? The first picture is the process from tappas_3.30.0_user_guide.pdf, page 110.


And the second picture is the bug from my operation.

It shows:

Fatal Python error: init_threadstate: thread state already initialized
Python runtime state: initialized
