@monroews The code referenced in the error seems to be from release v0.0.14. Are you sure that you are running code from version v0.0.15? You can use pip show aguaclara to check and, if the version is outdated, pip install aguaclara --upgrade to upgrade it.

I ran the pip show aguaclara command and I am using v0.0.15.

Problem solved! It turned out that the virtual environment linked to Hydrogen had version 13 of the aguaclara package. from aguaclara.play import * worked perfectly after upgrading to version 15.

@HannahSi thanks for figuring this out. I meant to take a look at it a while back but work has been very very busy recently. Feel free to keep assigning me things if you want me to take a look though!

[HannahSi]

@fletchapin No problem, I understand you're very busy! It turned out to be much easier to solve in person (in front of Monroe's computer). But thank you for keeping this on your mind, and I'll continue to keep you in the loop in the future!
