when i run the file run.sh, error occurs as follow:
Traceback (most recent call last):
File “compute_detector.py”, line 43, in

i have tried to install flufl.lock use "pip3 install flufl.lock",but it doesn't work. what should i do with this error?

I believe the code is intended to run in Python2, and the shebang also specifies that.
For flufl.lock, they stopped supporting python2 in recent versions, so you'll have to install the latest Python2 version through specifying the version number in pip.
