Are you upgrading from an older version of FiftyOne? Can you try uninstalling first and then reinstalling?

pip uninstall fiftyone fiftyone-brain fiftyone-db
pip install --upgrade fiftyone

Alternatively, can you try creating a fresh virtual environment?

I'm unable to reproduce this from a fresh virtual environment, eg:

conda create -n tmp python=3.9
conda activate tmp
pip install --upgrade fiftyone ipython
ipython

import fiftyone as fo
import fiftyone.zoo as foz

dataset = foz.load_zoo_dataset("quickstart")
session = fo.launch_app(dataset)

[KuenstlicheIntelligenz]

Ive upgraded, yes. Reinstalling didnt help. (ive just executed your code)

Fresh environment worked. A little bit unsatisfying, because if i install my old env again, it could be the same? But at least for now this solves my problem.

[KuenstlicheIntelligenz]

Unfortunately i dont know from which version i upgraded. I tried a few other minor versions e.g. 0.16.1 but they all had the same error.

0.15.1 is just stuck in "Pixelating" so is 0.14.4.

[Rusteam]

hi there, also stuck at pixelating after starting up the app: fiftyone app launch. No logs in a terminal.

system info:

• MacOS Monterrey (M1 chip)
• fiftyone=0.16.6 (pip installed)
• python=3.10.4

I am trying to reproduce yet. Still investigating.

For any upgrade/downgrade issues when using the App, I always recommend clearing the browser cache.

[Rusteam]

Surprisingly, the home page loaded after some idle time. It's working now for me :).

[brimoor]

If you encounter this again, I think the solution may just be to do a hard reload (Ctrl + Shift + R in Chrome, for example), or just to be extra safe, an "Empty Cache and Hard Reload" (in Chrome: open dev tools and then right-click the refresh icon)

[Rusteam]

Thanks I'll try clearing cache if it happens again. (I've tried with ctrl + shift + R, it didn't work)

[KuenstlicheIntelligenz]

For me clearing the cache didnt help. Tested Firefox and Chrome.

[benjaminpkane]

@KuenstlicheIntelligenz It looks like this error is coming from a network request. If you can share the response data from the network tab in dev tools, I can probably find the issue.

[KuenstlicheIntelligenz]

@benjaminpkane

Not sure exactly what you need. I'll just guess.

[benjaminpkane]

Perfect, thanks. The server is returning a 415 from /graphql, which I haven't seen before. It is odd because the request has the Content-Type header defined

Can you share your versions of hypercorn, starlette and strawberry-graphql?

pip list | grep "hypercorn"
pip list | grep "starlette"
pip list | grep "strawberry-graphql"

[KuenstlicheIntelligenz]

Hey, sorry for the late reply, was ill...

hypercorn                      0.14.2
sse-starlette                  0.10.3
starlette                      0.16.0
strawberry-graphql             0.96.0
