Hi Amelie, Thanks for the report! I think I have a fix for you. I've just issued this pull request: https://github.com/yt-project/yt/pull/4815 If you're able to pull it and test, have a go, but otherwise, you can make the changes (which are small and self-contained) yourself to: /home/wkal2/ENTER/envs/ml/lib/python3.9/site-packages/yt/frontends/athena/data_structures.py If it works for you, please report on the pull request and we can have it included -- or update to fix it. -Matt On Sat, Feb 10, 2024 at 7:54 PM A.

Dear yt Dev Team,

Hope this email finds you well! I am writing to seek assistance regarding an issue I encountered while attempting to load vtk files. Specifically, I am trying to extract data from vtk files generated by athena simulations using the ds.load function. However, the code returned the following error message,

Traceback (most recent call last):

File "/home/wkal2/rds/hpc-work/project/code/plot.py", line 13, in <module>

ds = yt.load(vtk_filename,parameters=parameters)

self.domain_dimensions[2] = np.int32(1)

ValueError: assignment destination is read-only

I would greatly appreciate any insights you can provide on what might be causing this issue with the code. For your reference, I am using yt version 4.3.0. Thank you for your attention and I look forward to hearing from you!

Best regards,
