Import Error: Cannot import name 'getitem_dataclass'

[sambaPython24]

Hey, thank you for that library and your work. When I try to run the examples, I get the following error:

ImportError: cannot import name 'getitem_dataclass' from 'phiml.math._magic_ops' (.../python3.11/site-packages/phiml/math/_magic_ops.py)

That looks like a version conflict. Could you upgrade the phiml library to 1.11 and send the full stack trace?

@holl-
Thank you for your answer:

The following minimal example yields

import phiml
print("phiml version: ",phiml.__version__)

from phi.flow import Box,Sphere,batch,union,geom,plot

gives the output

1.11.0

If we look at the relevant file in the phiml github repository, I indeed don't find a method getitem_dataclass availab

[sambaPython24]

I tried with some of the versions of the package (versions = "1.11.0, 1.10.2, 1.10.1, 1.10.0, 1.9.3, 1.9.2, 1.9.1, 1.9.0, 1.8.0, 1.7.5, 1.7.4, 1.7.3, 1.7.2, 1.7.1, 1.7.0.post1, 1.7.0, 1.6.0, 1.5.1, 1.5.0, 1.4.0, 1.3.1, 1.3.0, 1.2.1, 1.2.0, 1.1.0, 1.0.4, 1.0.3, 1.0.2, 1.0.1, 1.0.0"), but it is not available in any of them and the same error is coming.

Could that be an import error and you actually wanted to use the following
"""
from _dataclasses.py import getitem
"""
as this is the only method that appears to be close to the error.

Okay, I'll look into it. In the meantime, this should work

pip uninstall phiflow
pip install git+https://github.com/tum-pbs/PhiFlow@develop
pip uninstall phiml
pip install git+https://github.com/tum-pbs/PhiML@develop
