MedRawIO wrapper no longer works with dhn_med_py >= 2.0.x

[loicferreira]

Hello, this issue is related to this ticket

Describe the bug
The MedRawIO wrapper no longer works with the latest versions of dhn-med-py (>= 2.0.x).
It used to work correctly with dhn-med-py<=1.1.3, but the API changed in the 2.0.x release series (end of 2024 / early 2025, see PyPI history
).
As a result, the wrapper now fails when trying to load .medd folder.

To Reproduce
data is available in the related ticket (ephy_testing_data/med).
Install dhn-med-py>=2.0.0

from neo import io
folder_medd = "data_test.medd"
sess = io.MedIO(folder_medd,password="if_needed")

Environment:
OS: Windows
Python version: 3.12.10
Neo version: 0.14.2
NumPy version: 2.3.3
dhn-med-py version: 2.0.x (2.0.6 for my test)

Additional context
I noticed this issue when trying to open a .medd folder on macOS with Python 3.12.10. Older versions of dhn-med-py (<2.0.0) are incompatible with this Python version, which makes using the versions 2.0.x mandatory.
I’m not personally blocked by this issue, but I thought it might be useful for maintainers to be aware of the incompatibility in case updating the wrapper is of interest.

Thanks for reporting this!

@dancrepeau could you take a look at the issue?

We were told that they are trying to update their reader for numpy > 2.0 and that after that they would help us update our neo reader as the dhn-med-py library has api level changes that will make our reader incompatible when they are done updating. Just so everyone is on the loop for where we are at on this reader. We are not currently testing for this reader until the package is fully stable.
