The following wont run, how do I fix the errors at the bottom ? I’m trying to test the perimeter dectection.

cat testz.py  
import zymkey  
import time

zymkey.client.clear\_perimeter\_detect\_info()  
while True:  
print(zymkey.client.get\_perimeter\_detect\_info())  
time.sleep(1)

* * *

sudo pip install zymkey  
Requirement already satisfied: zymkey in /usr/local/lib/python2.7/dist-packages

Requirement already satisfied: PyYAML\>=3 in /usr/local/lib/python2.7/dist-packages (from cmdline\>=0.1.8-\>zymkey)

“zymkey” is an old deprecated library. The new library is called “zku”.

You must uninstall “zymkey” and install “zku” for things to work. BTW, if you had installed using our installer script, zku would have automatically installed. Any reason for not using the installer script?

I did use the install script about2 months ago. The example I found for testing the perimeter didn’t reference zku

Do you have an example zku test script for the perimeter ? I’m thinking it will work

Thanks

The API is the same in zku.
