Thanks for reporting this error. Can you provide the version of the Python sliderule package you are using?

import sliderule
print(sliderule.__version__)

[linxiong100]

the version is 1.4.6 when I am using pip install. It is not latest version by default.
I upgrade to version 4.7.1.
now it is working!
thanks!
