I am looking for a [PyPI package](https://pypi.org/project/drevalpy/) for a container. I cant find it in the list: > **[Containers | Seqera](https://seqera.io/containers/)** > > Fetch Docker & Singularity containers with any combination of Conda / PyPI packages, for free. Which packages are excluded from the list? Thanks!! ---

Hi @Pascal, Seqera Containers keeps a cache of package names and versions so that search results can be returned quickly. The process of updating this is currently manual and so new packages aren’t showing up. However, the good news is that we have mostly written the back-end code to use a new system which will always return results that are completely up to date. Hopefully it can be deployed soon (days-weeks from now). There’s a feature request tracking the same thing here: > **[Allow selecting versions on Seqera containers | Seqera Platform Feature...](https://feedback.seqera.io/feature-requests/p/allow-selecting-versions-on-seqera-containers)** > > It seems to be impossible to choose a version other than the default using https://seqera.io/containers/ Phil ---

Hi @Pascal, I’m happy to say that our rewritten and much-improved method for finding available packages is now live, and that the package you were searching for now shows up in the search results: ![CleanShot 2024-08-14 at 00.29.11@2x](https://europe1.discourse-cdn.com/flex013/uploads/seqera/original/1X/de18051064037fdfc9b3a89a20167cca4477cd5f.png) Hopefully this does the job for you, but do let us know if you find any other packages not behaving as they should!

That’s great to hear! As we’re still actively developing our package and corresponding pipeline, I’m wondering at what interval you are updating the package list 🙂 Like once a day? Best, Judith ---

I _think_ that it should update pretty much immediately. It does a fast result using our cache but then does a second slower check to the remote sources. If there are any differences then the page results update in place and our cache is updated. Maybe @vlad.savelyev can confirm this, as I’m not 100% sure about the cache behaviour.
