Creating a Dfs3 object fails

[watermain]

mikeio version 0.7.0 (tried the pip-installed one and also the current state in main) No problem on 0.6.4. Tried with a dfs3 file from mshe output and also with one created in MZ shell, error is the same.

code to reproduce:

import mikeio
dfsPath = r"C:\Users\uha\Documents\MIKE Zero Projects\MIKE_SHE\Karup_Basic\Karup_basic.she - Result Files HOT\Karup_basic_3DUZ.dfs3"
dfs3File = mikeio.dfs3.Dfs3(dfsPath)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\uha\OneDrive - DHI\DHIGitHub\mikeio\mikeio\dfs3.py", line 20, in __init__

@watermain can you confirm that the problem has been fixed and it works for you using mikeio 0.7.2? Thanks

Hi Jespers, works when installing the mikecore dev version! thanks - Uwe

Hi Uwe, I have now added mikecore>=0.1.2 to MIKE IO requirements. Hence it should now also work if you update MIKE IO :-)
