MIKEIO 1.6.3 is not working with the Pandas 2.1.3

[mohm-dhi]

Installing mikeio 1.6.3 now install pandas 2.1.3 as it dependency which is not compatible with mikeio. We should fix the pandas version to be less than 2. I tested this on a new environment that only had mikeio installed. Using mikeio 1.4.1 and Pandas 1.5.3 the problem solved but I need newer version of mikeio.

import mikeio

ds = mikeio.read("input/file.dfs2") print(ds)

to add to the above: installing mikeio 1.6.2 with pandas 2.1.3 works without problem 💯 why 1.6.3 is not working then !

Strange, I haven't seen any tests failing from the main branch related to pandas 2.1.3

Hi @mohm-dhi I don't see this issue, can you provide a failing test, that shows when it fails?

$ pip list|grep -e pandas -e mikeio
mikeio                        1.6.3
pandas                        2.1.3

I explained and showed you the way I tested it. I just created a new environment using python 3.10 and only pip install mikeio, then I run that simple code to read dfs2 files and show the results.

I tested that on docker too and same results. if you want I can quickly show you on a team call.

Well it is bedtime in Europe😴

Is this by any chance related to #620 or how come it is only relevant for Dfs2?

[mohm-dhi]

we can chat tomorrow. I did not test on other data type but will do.

[mohm-dhi]

I checked dfsu and it is working, I checked another dfs2 file and that works too. Strange, this Dfs2 that has problem supposed to be the standard dsf2 file that I download from MIKE Cloud. So probably an issue with this file.

[mohm-dhi]

I think you are right, it is related to that issue in the PR 620, it is only one time step in the file and that is the output when reading it using mikeio 1.6.2.
