strling-outliers.py: Incompatibility with newer Pandas version #119

Open ryanmcggg opened 4 months ago

ryanmcggg commented 4 months ago

Hello It looks like the strling-outliers.py script uses a Pandas indexing functionality that is no longer supported. I currently have Pandas 2.0.3, which I believe conda installed automatically following the strling instructions. It looks like you will have to re-write the pandas indexing to keep up to date. In the meantime, can you tell me which version of pandas you are using so that I can downgrade? Thanks! Error log below:

Convert to a numpy array before indexing instead.

Hi all,

I am having the same issue and would love to know which version of pandas to use. It seems to be a conflict with statsmodel, there are a few workarounds here, including downgrading to pandas 1.5.3 which I have not tried. I also noted seaborn and matplotlib are being installed by conda which reportedly cause the same issue, if they are not needed could they be removed from the conda package? This issue was also reported on the nf pipeline page here

Thanks 🙂 Gavin

Confirming I downgraded pandas from 2.2.0 to 1.5.3 and the error became a warning. Could you please check if this is ok, and if so, update the docker image? Thank you 🙂

The downgrade to Pandas 1.5.3 did work for me also. Thanks Gavin! It would be a good idea to update the script to keep up with the latest Pandas requirements though. Thanks, Ryan

Thank you both for catching the source of the issue! I'll work on updating to work with the latest version of Pandas.
