When I run the code, there is a question error

[zhitiankai]

When I ran the code, I encountered the following error.

/work4/zhitiankai/anaconda3/envs/py35milsed/lib/python3.5/site-packages/six.py in raise_from(value=RuntimeError('Failed to execute rubberband. Please verify that rubberband-cli is installed.',), from_value=FileNotFoundError(2, "No such file or directory: 'rubberband'"))

RuntimeError: Failed to execute rubberband. Please verify that rubberband-cli is installed.

Can you tell me what the problem is? My environment is based on py35 milsed.yml Configured.
thanks.

The error message says it all: you need to install rubberband-cli. https://breakfastquay.com/rubberband/
