Sounds like an installation issue on your end. How did you install?

[yurivict]

It is installed using the FreeBSD port system.

[ricardoV94]

I am not sure what that is. Even if it's not a solution can you try to pip install to confirm it's an installation issue and not a problem with your system.

I am pretty sure it would work with pip install, that's why I ask.

pip install can install packages, but it doesn't seem to be able to run tests.

etuples seems to be broken. The error is the same as pythological/etuples#24

[ricardoV94]

The test files aren't bundled with the pip package. Could you explain what you're trying to do exactly?

We have little resources to support alternative forms of installation. Our tests are designed for developers and they can be run if you clone the repo and install all dev requirements.

You can check the exact steps we use in the CI:

pytensor/.github/workflows/test.yml

Could you explain what you're trying to do exactly?

I am trying to make sure that the package runs after it was installed. Tests serve this purpose. I do this as part of maintaining/updating of the FreeBSD port.

If tests fail for whatever reason, this installation is faulty.

Maybe Python doesn't have such ability at the pip level, but the FreeBSD ports framework does support and encourage to run tests as part of the port update process.

I am trying to figure out what is wrong in this case.

[ricardoV94]

It might help if you could provide reproducible installation steps because I have no idea how you're trying to install.

Having said that, keep in mind there's little interest in our side in supporting alternative forms of installation other than pip and conda due to limited developer resources.

Our supported installation venues don't ship tests, because those are very thorough development oriented tests (it would take hours to run them locally). If you want a quick smoke test, then running the README might be good enough.

Have you tried to do this with pip installed PyTensor already?

PS: I am going to close your other issue because they all seem related to the unnoficial way you're trying to install the package.
