I see that you've linked to here from an issue in a fork of Aesara (i.e. pytensor); just so you know, these Pythological and Aesara projects are not associated with that fork and/or those developers.

[brandonwillard]

I can't reproduce this issue locally, so I created #25 to update some things in the project and to help determine if this issue has anything to do with our local setups.

[brandonwillard]

Again, it looks like your environment may be the cause of those issues.

[yurivict]

But what's wrong with the environment?
Virtually all python packages build fine in this environment.

How exactly is the environment being constructed? Can you provide a MWE?
