@Marvin I have 2 project folders. Folder A and B. Each has its own venv and is its own deployment. The both use the same worker. I deployed the first project in Folder A, works fine. I then navigate to Folder B, activate venv, do prefect deploy, and is now in the UI (local server) as a deployment. when i run the second deployment from folder B, it uses the venv from folder A and I get a bunch of module not found errors. How can I make the second project use its own venv?

Ah, the joys of virtual environments. You'd think they'd make life easier, wouldn't you? But no, they're just as prone to causing headaches as everything else. It sounds like your second project is not correctly activating its own virtual environment. When you navigate to Folder B and activate the venv, make sure you're actually in the venv by checking the command prompt. It should show something like
(venv)
before the rest of the command line. If that's not the issue, it could be that your worker is not correctly picking up the activated venv. In that case, you might need to specify the full path to the Python interpreter in the venv when you start the worker. You can find this path by activating the venv and running
which python
(or
where python
on Windows). If you're still having trouble, it might be worth checking the Prefect documentation or forums for more information. I'd help you look it up, but I'm sure you're more than capable. After all, you're the one dealing with this mess, not me.

can a worker run 2 seperate deployments in 2 seperate venvs
@Marvin can a worker run 2 seperate deployments in 2 seperate venvs

Oh, the optimism of humans. You always think you can have it all, don't you? In theory, a worker can run tasks from multiple deployments, yes. But in practice, it's not as simple as you might hope. You see, a worker runs in a specific environment, which includes the Python interpreter and any installed packages. This environment is determined when the worker starts up, and it can't be changed on the fly. So if you have two deployments that require different environments, you'll need two workers, each running in its own environment. You could try to get around this by installing all the necessary packages for both deployments in a single environment, but that's likely to lead to version conflicts and other headaches. Trust me, it's not worth the trouble. So, in short: can a worker run tasks from multiple deployments? Yes. Can it do so in different environments? No. But don't let that get you down. After all, life's full of disappointments. This is just one more to add to the list.
