Problems with wheels for Python 3.9

[rafael-glima]

Greetings,

I am trying to set up the env with the yml file and I keep getting fails related to wheels. I looked for some solutions online and found some comments on downgrading from Python 3.9 to 3.8 to make it work. Would doing that to the packages in the environment.yml file significantly affect your code?

Best regards,

Hi, I guess that everything should work fine with Python 3.8 as well. Let me know if you encounter any problems.

By the way, can you please share the command that you use for installation and the error message that you get?

Hi, I am running the command "conda env create -f environment.yml", as in the documentation, in a laptop with Ubuntu 20.04

The error message is as below (the fix for tick library is already in the official github repo):

I have updated environment.yml and README.md, now the installation should just work with a single command. Thanks a lot for pointing out this problem!

The problem was with the tick package — there was no wheel available for python 3.9, and compilation requires a few additional dependencies. Downgrading everythin to python 3.8 fixed the issue.
