About sswitch_runtime

[Eternity-Wang]

I meet this problem when I run the sentence "sudo python3 l2_learning_controller.py s1 cpu"
The problem：

Traceback (most recent call last):
File "/home/wly/p4-learning/exercises/04-L2_Learning/thrift/l2_learning_controller.py", line 4, in
from p4utils.utils.sswitch_thrift_API import SimpleSwitchThriftAPI
File "/home/wly/p4-utils/p4utils/utils/sswitch_thrift_API.py", line 34, in
from sswitch_runtime import SimpleSwitch
ModuleNotFoundError: No module named 'sswitch_runtime'

How can I fix it in a right way? Thanks.
