Okay that’s interesting
Okay can you upgrade kedro viz to the latest version
the toposort issue was fixed here https://github.com/kedro-org/kedro-viz/pull/1819
t
For python 3.8, i guess 7.1.0 is the maximum supported version
d
ah is that a hard requirement?
you’ve only got 5 months till it’s EOL? https://devguide.python.org/versions/
t
Yeah its an already working project which i am onboarded recently
j
Did you check
pip list | grep toposort
Have tired installing toposort manually
pip install toposort
and re run it.
t
@Jitendra Gundaniya that fixed the issue, thanks a ton 1000

@Jitendra Gundaniya it’s only going to be a problem for 5 months but you could release with this?
Copy code
toposort; python_version == '3.8.*'
j
Thanks @datajoely I will chat with @Rashida Kanchwala on this.

Is it a Python version problem? I think this is because Kedro drop
toposort
recently,
kedro-viz
assume
toposort
from
kedro
but it should actually put it in the requirements if
toposort
is imported inside viz codebase

hi team, we have already done this. and it was released in kedro-viz 9.0.1; however Kedro-viz dropped support for Python 3.8 recently. So you can't download the latest kedro-viz if you are on Python 3.8
