Hi team! I tried Experiment tracking in Kedro-Viz tutorial, and I can not open experiment tracking screen in

Access run data and compare runs

step. (Data fetching does not seem to be working and nothing is displayed.) error message(

kedro_viz\api\graphql\serializers.py

, line 46)

run_command=run_blob.get("cli", {}).get("command_path"),
AttributeError: 'str' object has no attribute 'get'

The environment and version are follows.

OS: windows
IDE: pycharm
venv: pyenv
python: 3.9.10
kedro: 0.18.5
kedro-viz: 0.5.3

The error log seems to indicate that the

run_blob

perse is not working. Actually I checked with degugger and

run_blob.get("cli", {})

was recognized as str, not dict. Is this a problem specific to my environment?

Hi @tomohiko kato and thank you for this very helpful and clear report and already getting started debugging on it! This looks to me like quite a bad bug but it’s very strange that no one has spotted it before because the code there has not changed for a while 🤔 As you say,

run_blob["cli"]

is giving a serialised string version of the dictionary rather than the dictionary itself. @Jannic Holzer do you have capacity to take a quick look at this? At a glance calls to

format_run

don’t even seem to be consistent about whether

run_blob

itself should be a str or a dict (as above, it should be a dictionary). I’m surprised mypy didn’t pick up on that 😕

@Jannic Holzer @Antony Milne -- I am getting the same error since yesterday. Maybe it's to do with the strawberry release.

Hmm yes, good thinking!

@tomohiko kato - are you trying to save the tracking data to a cloud storage like s3 or is it in on your local machine.

Also would be great if you could show the output of

pip show strawberry-graphql

🙂

Hey @Antony Milne I'll try to take a quick look today 🙂

Thank you for your quick reply! @Rashida Kanchwala

I'm trying to save it on my local machine.(I am following the tutorial step.) @Antony Milne

Also would be great if you could show the output of pip show strawberry-graphql 🙂

Here it is.

@tomohiko kato - this is a bug and we are working on releasing a fix for it soon.

For the time being though, it should all work fine with kedro 0.18.4. So I would recommend: • do

pip uninstall kedro && pip install kedro==0.18.4

to downgrade • assuming you’re just following a tutorial and don’t have any run information that you care about, delete your

data/session_store.db

file • you can keep the rest of the project as it is All should then work as per the tutorial 🙂

@Antony Milne @Rashida Kanchwala

All should then work as per the tutorial 🙂

I can see the experiment tracking page! Thank you for fixing the problem and developing a great product!

Thanks for letting us know @tomohiko kato and for your very helpful debugging! Have fun with kedro
