scripts/test_streamspot.py >>>node_num = int(p.stdout.readline())
error:
Traceback (most recent call last):
File "test_streamspot.py", line 246, in

File "test_streamspot.py", line 208, in main
node_num = int(p.stdout.readline())
ValueError: invalid literal for int() with base 10: b''

Why does this error occur and how to solve this problem?
